text: "Recent work emphasizes that the maximum entropy principle provides a bridge
between statistical mechanics models for collective behavior in neural networks
and experiments on networks of real neurons. Most of this work has focused on
capturing the measured correlations among pairs of neurons. Here we suggest an
alternative, constructing models that are consistent with the distribution of
global network activity, i.e. the probability that K out of N cells in the network
generate action potentials in the same small time bin. The inverse problem that
we need to solve in constructing the model is analytically tractable, and provides
a natural 'thermodynamics' for the network in the limit of large N. We analyze
the responses of neurons in a small patch of the retina to naturalistic stimuli,
and find that the implied thermodynamics is very close to an unusual critical
point, in which the entropy (in proper units) is exactly equal to the energy.

text: The number of possible activity patterns in a population of neurons grows
exponentially with the size of the population. Typical experiments explore only
a tiny fraction of the large space of possible activity patterns in the case of
populations with more than 10 or 20 neurons. It is thus impossible, in this undersampled
regime, to estimate the probabilities with which most of the activity patterns
occur. As a result, the corresponding entropy - which is a measure of the computational
power of the neural population - cannot be estimated directly. We propose a simple
scheme for estimating the entropy in the undersampled regime, which bounds its
value from both below and above. The lower bound is the usual 'naive' entropy
of the experimental frequencies. The upper bound results from a hybrid approximation
of the entropy which makes use of the naive estimate, a maximum entropy fit, and
a coverage adjustment. We apply our simple scheme to artificial data, in order
to check their accuracy; we also compare its performance to those of several previously
defined entropy estimators. We then apply it to actual measurements of neural
activity in populations with up to 100 cells. Finally, we discuss the similarities
and differences between the proposed simple estimation scheme and various earlier
methods. © 2013 IOP Publishing Ltd and SISSA Medialab srl.

text: In the vibrant field of optogenetics, optics and genetic targeting are combined
to commandeer cellular functions, such as the neuronal action potential, by optically
stimulating light-sensitive ion channels expressed in the cell membrane. One broadly
applicable manifestation of this approach are covalently attached photochromic
tethered ligands (PTLs) that allow activating ligand-gated ion channels with outstanding
spatial and temporal resolution. Here, we describe all steps towards the successful
development and application of PTL-gated ion channels in cell lines and primary
cells. The basis for these experiments forms a combination of molecular modeling,
genetic engineering, cell culture, and electrophysiology. The light-gated glutamate
receptor (LiGluR), which consists of the PTL-functionalized GluK2 receptor, serves
as a model.

text: 'In the hippocampus, cell assemblies forming mnemonic representations of space
are thought to arise as a result of changes in functional connections of pyramidal
cells. We have found that CA1 interneuron circuits are also reconfigured during
goal-oriented spatial learning through modification of inputs from pyramidal cells.
As learning progressed, new pyramidal assemblies expressed in theta cycles alternated
with previously established ones, and eventually overtook them. The firing patterns
of interneurons developed a relationship to new, learning-related assemblies:
some interneurons associated their activity with new pyramidal assemblies while
some others dissociated from them. These firing associations were explained by
changes in the weight of monosynaptic inputs received by interneurons from new
pyramidal assemblies, as these predicted the associational changes. Spatial learning
thus engages circuit modifications in the hippocampus that incorporate a redistribution
of inhibitory activity that might assist in the segregation of competing pyramidal
cell assembly patterns in space and time.'

text: Genomic imprinting leads to preferred expression of either the maternal or
paternal alleles of a subset of genes. Imprinting is essential for mammalian development,
and its deregulation causes many diseases. However, the functional relevance of
imprinting at the cellular level is poorly understood for most imprinted genes.
We used mosaic analysis with double markers (MADM) in mice to create uniparental
disomies (UPDs) and to visualize imprinting effects with single-cell resolution.
Although chromosome 12 UPD did not produce detectable phenotypes, chromosome 7
UPD caused highly significant paternal growth dominance in the liver and lung,
but not in the brain or heart. A single gene on chromosome 7, encoding the secreted
insulin-like growth factor 2 (IGF2), accounts for most of the paternal dominance
effect. Mosaic analyses implied additional imprinted loci on chromosome 7 acting
cell autonomously to transmit the IGF2 signal. Our study reveals chromosome- and
cell-type specificity of genomic imprinting effects.

text: 'G protein–coupled receptors (GPCRs), the largest family of membrane signaling
proteins, respond to neurotransmitters, hormones and small environmental molecules.
The neuronal function of many GPCRs has been difficult to resolve because of an
inability to gate them with subtype specificity, spatial precision, speed and
reversibility. To address this, we developed an approach for opto-chemical engineering
of native GPCRs. We applied this to the metabotropic glutamate receptors (mGluRs)
to generate light-agonized and light-antagonized mGluRs (LimGluRs). The light-agonized
LimGluR2, on which we focused, was fast, bistable and supported multiple rounds
of on/off switching. Light gated two of the primary neuronal functions of mGluR2:
suppression of excitability and inhibition of neurotransmitter release. We found
that the light-antagonized tool LimGluR2-block was able to manipulate negative
feedback of synaptically released glutamate on transmitter release. We generalized
the optical control to two additional family members: mGluR3 and mGluR6. This
system worked in rodent brain slices and in zebrafish in vivo, where we found
that mGluR2 modulated the threshold for escape behavior. These light-gated mGluRs
pave the way for determining the roles of mGluRs in synaptic plasticity, memory
and disease.'

text: Given a continuous function f:X-R on a topological space, we consider the
preimages of intervals and their homology groups and show how to read the ranks
of these groups from the extended persistence diagram of f. In addition, we quantify
the robustness of the homology classes under perturbations of f using well groups,
and we show how to read the ranks of these groups from the same extended persistence
diagram. The special case X=R3 has ramifications in the fields of medical imaging
and scientific visualization.

text: Neural populations encode information about their stimulus in a collective
fashion, by joint activity patterns of spiking and silence. A full account of
this mapping from stimulus to neural activity is given by the conditional probability
distribution over neural codewords given the sensory input. For large populations,
direct sampling of these distributions is impossible, and so we must rely on constructing
appropriate models. We show here that in a population of 100 retinal ganglion
cells in the salamander retina responding to temporal white-noise stimuli, dependencies
between cells play an important encoding role. We introduce the stimulus-dependent
maximum entropy (SDME) model—a minimal extension of the canonical linear-nonlinear
model of a single neuron, to a pairwise-coupled neural population. We find that
the SDME model gives a more accurate account of single cell responses and in particular
significantly outperforms uncoupled models in reproducing the distributions of
population codewords emitted in response to a stimulus. We show how the SDME model,
in conjunction with static maximum entropy models of population vocabulary, can
be used to estimate information-theoretic quantities like average surprise and
information transmission in a neural population.

text: Motile cilia perform crucial functions during embryonic development and throughout
adult life. Development of organs containing motile cilia involves regulation
of cilia formation (ciliogenesis) and formation of a luminal space (lumenogenesis)
in which cilia generate fluid flows. Control of ciliogenesis and lumenogenesis
is not yet fully understood, and it remains unclear whether these processes are
coupled. In the zebrafish embryo, lethal giant larvae 2 (lgl2) is expressed prominently
in ciliated organs. Lgl proteins are involved in establishing cell polarity and
have been implicated in vesicle trafficking. Here, we identified a role for Lgl2
in development of ciliated epithelia in Kupffer's vesicle, which directs left-right
asymmetry of the embryo; the otic vesicles, which give rise to the inner ear;
and the pronephric ducts of the kidney. Using Kupffer's vesicle as a model ciliated
organ, we found that depletion of Lgl2 disrupted lumen formation and reduced cilia
number and length. Immunofluorescence and time-lapse imaging of Kupffer's vesicle
morphogenesis in Lgl2-deficient embryos suggested cell adhesion defects and revealed
loss of the adherens junction component E-cadherin at lateral membranes. Genetic
interaction experiments indicate that Lgl2 interacts with Rab11a to regulate E-cadherin
and mediate lumen formation that is uncoupled from cilia formation. These results
uncover new roles and interactions for Lgl2 that are crucial for both lumenogenesis
and ciliogenesis and indicate that these processes are genetically separable in
zebrafish.

text: We consider a two-parameter family of piecewise linear maps in which the moduli
of the two slopes take different values. We provide numerical evidence of the
existence of some parameter regions in which the Lyapunov exponent and the topological
entropy remain constant. Analytical proof of this phenomenon is also given for
certain cases. Surprisingly however, the systems with that property are not conjugate
as we prove by using kneading theory.

text: 'Premise of the study: To reach favorable conditions for photosynthesis, seedlings
grow upward when deprived of light upon underground germination. To direct their
growth, they use their negative gravitropic capacity. Negative gravitropism is
under tight control of multiple hormones. • Methods: By counting the number of
standing plants in a population or by real time monitoring of the reorientation
of gravistimulated seedlings of Arabidopsis thaliana, we evaluated the negative
gravitropism of ethylene or brassinosteroid (BR) treated plants. Meta-analysis
of transcriptomic data on AUX / IAA genes was gathered, and subsequent mutant
analysis was performed. • Key results: Ethylene and BR have opposite effects in
regulating shoot gravitropism. Lack of BR enhances gravitropic reorientation in
2-d-old seedlings, whereas ethylene does not. Lack of ethylene signaling results
in enhanced BR sensitivity. Ethylene and BRs regulate overlapping sets of AUX
/ IAA genes. BRs regulate a wider range of auxin signaling components than ethylene.
• Conclusions: Upward growth in seedlings depends strongly on the internal hormonal
balance. Endogenous ethylene stimulates, whereas BRs reduce negative gravitropism
in a manner that depends on the function of different, yet overlapping sets of
auxin signaling components.'

text: Plant architecture is influenced by the polar, cell-to-cell transport of auxin
that is primarily provided and regulated by plasma membrane efflux catalysts of
the PIN-FORMED and B family of ABC transporter (ABCB) classes. The latter were
shown to require the functionality of the FK506 binding protein42 TWISTED DWARF1
(TWD1), although underlying mechanisms are unclear. By genetic manipulation of
TWD1 expression, we show here that TWD1 affects shootward root auxin reflux and,
thus, downstream developmental traits, such as epidermal twisting and gravitropism
of the root. Using immunological assays, we demonstrate a predominant lateral,
mainly outward-facing, plasma membrane location for TWD1 in the root epidermis
characterized by the lateral marker ABC transporter G36/PLEIOTROPIC DRUG-RESISTANCE8/PENETRATION3.
At these epidermal plasma membrane domains, TWD1 colocalizes with nonpolar ABCB1.
In planta bioluminescence resonance energy transfer analysis was used to verify
specific ABC transporter B1 (ABCB1)-TWD1 interaction. Our data support a model
in which TWD1 promotes lateral ABCB-mediated auxin efflux via protein-protein
interaction at the plasma membrane, minimizing reflux from the root apoplast into
the cytoplasm.

text: Lateral root (LR) formation is initiated when pericycle cells accumulate auxin,
thereby acquiring founder cell (FC) status and triggering asymmetric cell divisions,
giving rise to a new primordium. How this auxin maximum in pericycle cells builds
up and remains focused is not understood. We report that the endodermis plays
an active role in the regulation of auxin accumulation and is instructive for
FCs to progress during the LR initiation (LRI) phase. We describe the functional
importance of a PIN3 (PIN-formed) auxin efflux carrier-dependent hormone reflux
pathway between overlaying endodermal and pericycle FCs. Disrupting this reflux
pathway causes dramatic defects in the progress of FCs towards the next initiation
phase. Our data identify an unexpected regulatory function for the endodermis
in LRI as part of the fine-tuning mechanism that appears to act as a check point
in LR organogenesis after FCs are specified.

text: Gravitropic bending of plant organs is mediated by an asymmetric signaling
of the plant hormone auxin between the upper and lower side of the respective
organ. Here, we show that also another plant hormone, gibberellic acid (GA), shows
asymmetric action during gravitropic responses. Immunodetection using an antibody
against GA and monitoring GA signaling output by downstream degradation of DELLA
proteins revealed an asymmetric GA distribution and response with the maximum
at the lower side of gravistimulated roots. Genetic or pharmacological manipulation
of GA levels or response affects gravity-mediated auxin redistribution and root
bending response. The higher GA levels at the lower side of the root correlate
with increased amounts of PIN-FORMED2 (PIN2) auxin transporter at the plasma membrane.
The observed increase in PIN2 stability is caused by a specific GA effect on trafficking
of PIN proteins to lytic vacuoles that presumably occurs downstream of brefeldin
A-sensitive endosomes. Our results suggest that asymmetric auxin distribution
instructive for gravity-induced differential growth is consolidated by the asymmetric
action of GA that stabilizes the PIN-dependent auxin stream along the lower side
of gravistimulated roots.

text: The puzzle piece-shaped Arabidopsis leaf pavement cells (PCs) with interdigitated
lobes and indents is a good model system to investigate the mechanisms that coordinate
cell polarity and shape formation within a tissue. Auxin has been shown to coordinate
the interdigitation by activating ROP GTPase-dependent signaling pathways. To
identify additional components or mechanisms, we screened for mutants with abnormal
PC morphogenesis and found that cytokinin signaling regulates the PC interdigitation
pattern. Reduction in cytokinin accumulation and defects in cytokinin signaling
(such as in ARR7-over-expressing lines, the ahk3cre1 cytokinin receptor mutant,
and the ahp12345 cytokinin signaling mutant) enhanced PC interdigitation, whereas
over-production of cytokinin and over-activation of cytokinin signaling in an
ARR20 over-expression line delayed or abolished PC interdigitation throughout
the cotyledon. Genetic and biochemical analyses suggest that cytokinin signaling
acts upstream of ROPs to suppress the formation of interdigitated pattern. Our
results provide novel mechanistic understanding of the pathways controlling PC
shape and uncover a new role for cytokinin signaling in cell morphogenesis.

text: We focus on the realizability problem of Message Sequence Graphs (MSG), i.e.
the problem whether a given MSG specification is correctly distributable among
parallel components communicating via messages. This fundamental problem of MSG
is known to be undecidable. We introduce a well motivated restricted class of
MSG, so called controllable-choice MSG, and show that all its models are realizable
and moreover it is decidable whether a given MSG model is a member of this class.
In more detail, this class of MSG specifications admits a deadlock-free realization
by overloading existing messages with additional bounded control data. We also
show that the presented class is the largest known subclass of MSG that allows
for deadlock-free realization.

text: 'Root system growth and development is highly plastic and is influenced by
the surrounding environment. Roots frequently grow in heterogeneous environments
that include interactions from neighboring plants and physical impediments in
the rhizosphere. To investigate how planting density and physical objects affect
root system growth, we grew rice in a transparent gel system in close proximity
with another plant or a physical object. Root systems were imaged and reconstructed
in three dimensions. Root-root interaction strength was calculated using quantitative
metrics that characterize the extent towhich the reconstructed root systems overlap
each other. Surprisingly, we found the overlap of root systems of the same genotype
was significantly higher than that of root systems of different genotypes. Root
systems of the same genotype tended to grow toward each other but those of different
genotypes appeared to avoid each other. Shoot separation experiments excluded
the possibility of aerial interactions, suggesting root communication. Staggered
plantings indicated that interactions likely occur at root tips in close proximity.
Recognition of obstacles also occurred through root tips, but through physical
contact in a size-dependent manner. These results indicate that root systems use
two different forms of communication to recognize objects and alter root architecture:
root-root recognition, possibly mediated through root exudates, and root-object
recognition mediated by physical contact at the root tips. This finding suggests
that root tips act as local sensors that integrate rhizosphere information into
global root architectural changes.'

text: ' We introduce the M-modes problem for graphical models: predicting the M
label configurations of highest probability that are at the same time local maxima
of the probability landscape. M-modes have multiple possible applications: because
they are intrinsically diverse, they provide a principled alternative to non-maximum
suppression techniques for structured prediction, they can act as codebook vectors
for quantizing the configuration space, or they can form component centers for
mixture model approximation. We present two algorithms for solving the M-modes
problem. The first algorithm solves the problem in polynomial time when the underlying
graphical model is a simple chain. The second algorithm solves the problem for
junction chains. In synthetic and real dataset, we demonstrate how M-modes can
improve the performance of prediction. We also use the generated modes as a tool
to understand the topography of the probability distribution of configurations,
for example with relation to the training set size and amount of noise in the
data. '
