text: In vitro work revealed that excitatory synaptic inputs to hippocampal inhibitory
interneurons could undergo Hebbian, associative, or non-associative plasticity.
Both behavioral and learning-dependent reorganization of these connections has
also been demonstrated by measuring spike transmission probabilities in pyramidal
cell-interneuron spike cross-correlations that indicate monosynaptic connections.
Here we investigated the activity-dependent modification of these connections
during exploratory behavior in rats by optogenetically inhibiting pyramidal cell
and interneuron subpopulations. Light application and associated firing alteration
of pyramidal and interneuron populations led to lasting changes in pyramidal-interneuron
connection weights as indicated by spike transmission changes. Spike transmission
alterations were predicted by the light-mediated changes in the number of pre-
and postsynaptic spike pairing events and by firing rate changes of interneurons
but not pyramidal cells. This work demonstrates the presence of activity-dependent
associative and non-associative reorganization of pyramidal-interneuron connections
triggered by the optogenetic modification of the firing rate and spike synchrony
of cells.

text: Hippocampal activity patterns representing movement trajectories are reactivated
in immobility and sleep periods, a process associated with memory recall, consolidation,
and decision making. It is thought that only fixed, behaviorally relevant patterns
can be reactivated, which are stored across hippocampal synaptic connections.
To test whether some generalized rules govern reactivation, we examined trajectory
reactivation following non-stereotypical exploration of familiar open-field environments.
We found that random trajectories of varying lengths and timescales were reactivated,
resembling that of Brownian motion of particles. The animals’ behavioral trajectory
did not follow Brownian diffusion demonstrating that the exact behavioral experience
is not reactivated. Therefore, hippocampal circuits are able to generate random
trajectories of any recently active map by following diffusion dynamics. This
ability of hippocampal circuits to generate representations of all behavioral
outcome combinations, experienced or not, may underlie a wide variety of hippocampal-dependent
cognitive functions such as learning, generalization, and planning.

text: Hippocampus is needed for both spatial working and reference memories. Here,
using a radial eight-arm maze, we examined how the combined demand on these memories
influenced CA1 place cell assemblies while reference memories were partially updated.
This was contrasted with control tasks requiring only working memory or the update
of reference memory. Reference memory update led to the reward-directed place
field shifts at newly rewarded arms and to the gradual strengthening of firing
in passes between newly rewarded arms but not between those passes that included
a familiar-rewarded arm. At the maze center, transient network synchronization
periods preferentially replayed trajectories of the next chosen arm in reference
memory tasks but the previously visited arm in the working memory task. Hence,
reference memory demand was uniquely associated with a gradual, goal novelty-related
reorganization of place cell assemblies and with trajectory replay that reflected
the animal's decision of which arm to visit next.

text: Grid cells with their rigid hexagonal firing fields are thought to provide
an invariant metric to the hippocampal cognitive map, yet environmental geometrical
features have recently been shown to distort the grid structure. Given that the
hippocampal role goes beyond space, we tested the influence of nonspatial information
on the grid organization. We trained rats to daily learn three new reward locations
on a cheeseboard maze while recording from the medial entorhinal cortex and the
hippocampal CA1 region. Many grid fields moved toward goal location, leading to
long-lasting deformations of the entorhinal map. Therefore, distortions in the
grid structure contribute to goal representation during both learning and recall,
which demonstrates that grid cells participate in mnemonic coding and do not merely
provide a simple metric of space.

text: The hippocampus is thought to initiate systems-wide mnemonic processes through
the reactivation of previously acquired spatial and episodic memory traces, which
can recruit the entorhinal cortex as a first stage of memory redistribution to
other brain areas. Hippocampal reactivation occurs during sharp wave-ripples,
in which synchronous network firing encodes sequences of places.We investigated
the coordination of this replay by recording assembly activity simultaneously
in the CA1 region of the hippocampus and superficial layers of the medial entorhinal
cortex. We found that entorhinal cell assemblies can replay trajectories independently
of the hippocampus and sharp wave-ripples. This suggests that the hippocampus
is not the sole initiator of spatial and episodic memory trace reactivation. Memory
systems involved in these processes may include nonhierarchical, parallel components.

text: During hippocampal sharp wave/ripple (SWR) events, previously occurring, sensory
inputdriven neuronal firing patterns are replayed. Such replay is thought to be
important for plasticity- related processes and consolidation of memory traces.
It has previously been shown that the electrical stimulation-induced disruption
of SWR events interferes with learning in rodents in different experimental paradigms.
On the other hand, the cognitive map theory posits that the plastic changes of
the firing of hippocampal place cells constitute the electrophysiological counterpart
of the spatial learning, observable at the behavioral level. Therefore, we tested
whether intact SWR events occurring during the sleep/rest session after the first
exploration of a novel environment are needed for the stabilization of the CA1
code, which process requires plasticity. We found that the newly-formed representation
in the CA1 has the same level of stability with optogenetic SWR blockade as with
a control manipulation that delivered the same amount of light into the brain.
Therefore our results suggest that at least in the case of passive exploratory
behavior, SWR-related plasticity is dispensable for the stability of CA1 ensembles.

text: Hippocampal neurons encode a cognitive map of space. These maps are thought
to be updated during learning and in response to changes in the environment through
activity-dependent synaptic plasticity. Here we examine how changes in activity
influence spatial coding in rats using halorhodopsin-mediated, spatially selective
optogenetic silencing. Halorhoposin stimulation leads to light-induced suppression
in many place cells and interneurons; some place cells increase their firing through
disinhibition, whereas some show no effect. We find that place fields of the unaffected
subpopulation remain stable. On the other hand, place fields of suppressed place
cells were unstable, showing remapping across sessions before and after optogenetic
inhibition. Disinhibited place cells had stable maps but sustained an elevated
firing rate. These findings suggest that place representation in the hippocampus
is constantly governed by activity-dependent processes, and that disinhibition
may provide a mechanism for rate remapping.

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: The hippocampus is an important brain circuit for spatial memory and the spatially
selective spiking of hippocampal neuronal assemblies is thought to provide a mnemonic
representation of space. We found that remembering newly learnt goal locations
required NMDA receptorĝ€"dependent stabilization and enhanced reactivation
of goal-related hippocampal assemblies. During spatial learning, place-related
firing patterns in the CA1, but not CA3, region of the rat hippocampus were reorganized
to represent new goal locations. Such reorganization did not occur when goals
were marked by visual cues. The stabilization and successful retrieval of these
newly acquired CA1 representations of behaviorally relevant places was NMDAR dependent
and necessary for subsequent memory retention performance. Goal-related assembly
patterns associated with sharp wave/ripple network oscillations, during both learning
and subsequent rest periods, predicted memory performance. Together, these results
suggest that the reorganization and reactivation of assembly firing patterns in
the hippocampus represent the formation and expression of new spatial memory traces.

text: Episodic and spatial memories each involve the encoding of complex associations
in hippocampal neuronal circuits. Such memory traces could be stabilised from
short- to long-term forms by consolidation processes involving the 'reactivation'
of the original network firing patterns during sleep and rest. Waking experience
can be replayed in many different brain areas, but an important role for the hippocampus
lies in the organisation of the 'reactivation' process. Emerging evidence suggests
that sharp wave/ripple (SWR) events in the hippocampus could coordinate the reactivation
of memory traces and direct their reinstatement in cortical circuits. Although
the mechanisms remain uncertain, there is a growing consensus that such SWR-directed
reactivation of brain-wide memory traces could underlie memory consolidation.

text: The hippocampus is thought to be involved in episodic memory formation by
reactivating traces of waking experience during sleep. Indeed, the joint firing
of spatially tuned pyramidal cells encoding nearby places recur during sleep.
We found that the sleep cofiring of rat CA1 pyramidal cells encoding similar places
increased relative to the sleep session before exploration. This cofiring increase
depended on the number of times that cells fired together with short latencies
( < 50 ms) during exploration, and was strongest between cells representing
the most visited places. This is indicative of a Hebbian learning rule in which
changes in firing associations between cells are determined by the number of waking
coincident firing events. In contrast, cells encoding different locations reduced
their cofiring in proportion to the number of times that they fired independently.
Together these data indicate that reactivated patterns are shaped by both positive
and negative changes in cofiring, which are determined by recent behavior.

text: 'Hippocampal place cells that fire together within the same cycle of theta
oscillations represent the sequence of positions (movement trajectory) that a
rat traverses on a linear track. Furthermore, it has been suggested that the encoding
of these and other types of temporal memory sequences is organized by gamma oscillations
nested within theta oscillations. Here, we examined whether gamma-related firing
of place cells permits such discrete temporal coding. We found that gamma-modulated
CA1 pyramidal cells separated into two classes on the basis of gamma firing phases
during waking theta periods. These groups also differed in terms of their spike
waveforms, firing rates, and burst firing tendency. During gamma oscillations
one group''s firing became restricted to theta phases associated with the highest
gamma power. Consequently, on the linear track, cells in this group often failed
to fire early in theta-phase precession (as the rat entered the place field) if
gamma oscillations were present. The second group fired throughout the theta cycle
during gamma oscillations, and maintained gamma-modulated firing at different
stages of theta-phase precession. Our results suggest that the two different pyramidal
cell classes may support different types of population codes within a theta cycle:
one in which spike sequences representing movement trajectories occur across subsequent
gamma cycles nested within each theta cycle, and another in which firing in synchronized
gamma discharges without temporal sequences encode a representation of location.
We propose that gamma oscillations during theta-phase precession organize the
mnemonic recall of population patterns representing places and movement paths.'

text: On the linear track, the recent firing sequences of CA1 place cells recur
during sharp wave/ripple patterns (SWRs) in a reverse temporal order [Foster &
Wilson (2006) Nature, 440, 680-683]. We have found similar reverse-order reactivation
during SWRs in open-field exploration where the firing sequence of cells varied
before each SWR. Both the onset times and the firing patterns of cells showed
a tendency for reversed sequences during SWRs. These effects were observed for
SWRs that occurred during exploration, but not for those during longer immobility
periods. Additionally, reverse reactivation was stronger when it was preceded
by higher speed (> 5 cm/s) run periods. The trend for reverse-order SWR reactivation
was not significantly different in familiar and novel environments, even though
SWR-associated firing rates of both pyramidal cells and interneurons were reduced
in novel environments as compared with familiar. During exploration-associated
SWRs (eSWR) place cells retain place-selective firing [O'Neill et al. (2006) Neuron,
49, 143-155]. Here, we have shown that each cell's firing onset was more delayed
and firing probability more reduced during eSWRs the further the rat was from
the middle of the cell's place field; that is, cells receiving less momentary
place-related excitatory drive fired later during SWR events. However, even controlling
for place field distance, the recent firing of cells was still significantly correlated
with SWR reactivation sequences. We therefore propose that both place-related
drive and the firing history of cells contribute to reverse reactivation during
eSWRs.

text: We observed sharp wave/ripples (SWR) during exploration within brief (<
2.4 s) interruptions of or during theta oscillations. CA1 network responses of
SWRs occurring during exploration (eSWR) and SWRs detected in waking immobility
or sleep were similar. However, neuronal activity during eSWR was location dependent,
and eSWR-related firing was stronger inside the place field than outside. The
eSPW-related firing increase was stronger than the baseline increase inside compared
to outside, suggesting a “supralinear” summation of eSWR and place-selective inputs.
Pairs of cells with similar place fields and/or correlated firing during exploration
showed stronger coactivation during eSWRs and subsequent sleep-SWRs. Sequential
activation of place cells was not required for the reactivation of waking co-firing
patterns; cell pairs with symmetrical cross-correlations still showed reactivated
waking co-firing patterns during sleep-SWRs. We suggest that place-selective firing
during eSWRs facilitates initial associations between cells with similar place
fields that enable place-related ensemble patterns to recur during subsequent
sleep-SWRs.

text: In the hippocampal CA1 area, a relatively homogenous population of pyramidal
cells is accompanied by a diversity of GABAergic interneurons. Previously, we
found that parvalbumin-expressing basket, axo-axonic, bistratified, and oriens-lacunosum
moleculare cells, innervating different domains of pyramidal cells, have distinct
firing patterns during network oscillations in vivo. A second family of interneurons,
expressing cholecystokinin but not parvalbumin, is known to target the same domains
of pyramidal cells as do the parvalbumin cells. To test the temporal activity
of these independent and parallel GABAergic inputs, we recorded the precise spike
timing of identified cholecystokinin interneurons during hippocampal network oscillations
in anesthetized rats and determined their molecular expression profiles and synaptic
targets. The cells were cannabinoid receptor type 1 immunopositive. Contrary to
the stereotyped firing of parvalbumin interneurons, cholecystokinin-expressing
basket and dendrite-innervating cells discharge, on average, with 1.7 ± 2.0 Hz
during high-frequency ripple oscillations in an episode-dependent manner. During
theta oscillations, cholecystokinin- expressing interneurons fire with 8.8 ± 3.3
Hz at a characteristic time on the ascending phase of theta waves (155 ± 81°),
when place cells start firing in freely moving animals. The firing patterns of
some interneurons recorded in drug-free behaving rats were similar to cholecystokinin
cells in anesthetized animals. Our results demonstrate that cholecystokinin- and
parvalbumin-expressing interneurons make different contributions to network oscillations
and play distinct roles in different brain states. We suggest that the specific
spike timing of cholecystokinin interneurons and their sensitivity to endocannabinoids
might contribute to differentiate subgroups of pyramidal cells forming neuronal
assemblies, whereas parvalbumin interneurons contribute to synchronizing the entire
network. Copyright © 2005 Society for Neuroscience.
