For the result from these measurement to be meaningful, a common data set of ground truth is required. We therefore started with the buildup of a document image database that is meant to serve as a common data basis for all kinds of restoration from images of 3D-shaped document.

We found that for low mutation rates the qualitative evolutionary behavior is robust with respect to the scaling of the fitness function. For efficient mutation rates, which are close to the error threshold, scaling and distance measure have a strong influence on the evolutionary behavior. A global distance measure that takes sequence information additively into account lowers the error threshold. When using a local sequence-structure alignment for the distance, we observed a smoother evolution of the fitness over time.

However, Ih in inhibitory GABAergic interneurons is less well characterized. We examined the functional properties of Ih in fast-spiking basket cells (BCs) of the dentate gyrus, using hippocampal slices from 17- to 21-day-old rats. Bath application of the Ih channel blocker ZD 7288 at a concentration of 30 microm induced a hyperpolarization of 5.7 +/- 1.5 mV, an increase in input resistance and a correlated increase in apparent membrane time constant. ZD 7288 blocked a hyperpolarization-activated current in a concentration-dependent manner (IC50, 1.4 microm). The effects of ZD 7288 were mimicked by external Cs+. The reversal potential of Ih was -27.4 mV, corresponding to a Na+ to K+ permeability ratio (PNa/PK) of 0.36. The midpoint potential of the activation curve of Ih was -83.9 mV, and the activation time constant at -120 mV was 190 ms. Single-cell expression analysis using reverse transcription followed by quantitative polymerase chain reaction revealed that BCs coexpress HCN1 and HCN2 subunit mRNA, suggesting the formation of heteromeric HCN1/2 channels. ZD 7288 increased the current threshold for evoking antidromic action potentials by extracellular stimulation, consistent with the expression of Ih in BC axons. Finally, ZD 7288 decreased the frequency of miniature inhibitory postsynaptic currents (mIPSCs) in hippocampal granule cells, the main target cells of BCs, to 70 +/- 4% of the control value. In contrast, the amplitude of mIPSCs was unchanged, consistent with the presence of Ih in inhibitory terminals. In conclusion, our results suggest that Ih channels are expressed in the somatodendritic region, axon and presynaptic elements of fast-spiking BCs in the hippocampus.","lang":"eng"}],"quality_controlled":0,"publisher":"Wiley-Blackwell","main_file_link":[{"open_access":"1","url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1817792/"}],"oa":1,"month":"01","intvolume":" 574"},{"_id":"3814","type":"review","status":"public","citation":{"ista":"Frotscher M, Jonas PM, Sloviter R. 2006.

Interneurons of the hilar region and area CA3 are also prominent targets of mossy fibers. The tracing of biocytin-filled mossy fibers and immunolabeling of target cells with interneuron markers has revealed that the majority of mossy fiber synapses project to gamma aminobutyric acid (GABA)-ergic inhibitory interneurons rather than to excitatory principal cells, although the functional implications of these quantitative differences are unclear. Following a brief description of the "classical" mossy fiber synapse on excrescences of CA3 pyramidal cells, the present review focuses on the contacts formed between granule cells and GABAergic interneurons, both normally and after synaptic reorganization. In response to deafferentation of mossy cell target cells, which include both granule cells and interneurons, mossy fibers "sprout" new axon collaterals that form a band of supragranular mossy fibers in the inner molecular layer of the dentate gyrus. Although most newly formed recurrent mossy fibers establish synapses with granule cells, there is an apparently convergent input of new mossy fibers onto GABA-immunoreactive interneuron dendrites that traverse the inner molecular layer. These mossy fiber-interneuron synapses in the dentate gyrus are observed in chronically epileptic rats and may be the structural correlate of the granule cell hyperinhibition observed in these animals in vivo. Together, the findings reviewed here establish mossy fiber synapses as an important component of inhibitory circuits in the hippocampus.","lang":"eng"}],"publisher":"Springer","quality_controlled":0,"month":"01","intvolume":" 326","year":"2006","publication_status":"published","day":"01","publication":"Cell and Tissue Research","page":"361 - 7","issue":"2","volume":326,"doi":"10.1007/s00441-006-0269-2","date_published":"2006-01-01T00:00:00Z","date_created":"2018-12-11T12:05:19Z"},{"title":"Timing and efficacy of transmitter release at mossy fiber synapses in the hippocampal network","publist_id":"2396","author":[{"last_name":"Bischofberger","full_name":"Bischofberger, Josef","first_name":"Josef"},{"full_name":"Engel, Dominique","last_name":"Engel","first_name":"Dominique"},{"first_name":"Michael","full_name":"Frotscher, Michael","last_name":"Frotscher"},{"first_name":"Peter M","id":"353C1B58-F248-11E8-B48F-1D18A9856A87","last_name":"Jonas","full_name":"Peter Jonas","orcid":"0000-0001-5001-4804"}],"extern":1,"date_updated":"2021-01-12T07:52:24Z","citation":{"short":"J.

Recent work, partially based on direct presynaptic patch-clamp recordings from hippocampal mossy fiber boutons, sheds light on the mechanisms of synaptic transmission and plasticity at mossy fiber synapses. A high Na(+) channel density in mossy fiber boutons leads to a large amplitude of the presynaptic action potential. Together with the fast gating of presynaptic Ca(2+) channels, this generates a large and brief presynaptic Ca(2+) influx, which can trigger transmitter release with high efficiency and temporal precision. The large number of release sites, the large size of the releasable pool of vesicles, and the huge extent of presynaptic plasticity confer unique strength to this synapse, suggesting a large impact onto the CA3 pyramidal cell network under specific behavioral conditions.

Computational studies suggested that the emergence of coherent oscillations requires hyperpolarizing inhibition. Here, we show that GABA(A) receptor-mediated inhibition in mature interneurons of the hippocampal dentate gyrus is shunting rather than hyperpolarizing. Unexpectedly, when shunting inhibition is incorporated into a structured interneuron network model with fast and strong synapses, coherent oscillations emerge. In comparison to hyperpolarizing inhibition, networks with shunting inhibition show several advantages. First, oscillations are generated with smaller tonic excitatory drive. Second, network frequencies are tuned to the gamma band. Finally, robustness against heterogeneity in the excitatory drive is markedly improved. In single interneurons, shunting inhibition shortens the interspike interval for low levels of drive but prolongs it for high levels, leading to homogenization of neuronal firing rates. Thus, shunting inhibition may confer increased robustness to gamma oscillations in the brain.","lang":"eng"}],"quality_controlled":0,"publisher":"Elsevier","month":"01","intvolume":" 49","year":"2006","publication_status":"published","day":"01","publication":"Neuron","page":"107 - 17","doi":"10.1016/j.neuron.2005.11.036","date_published":"2006-01-01T00:00:00Z","volume":49,"issue":"1","date_created":"2018-12-11T12:05:18Z"},{"status":"public","type":"journal_article","_id":"3817","title":"The most important recent advances in synapse research from my point of view--and what remains to be done","author":[{"full_name":"Frotscher, Michael","last_name":"Frotscher","first_name":"Michael"},{"last_name":"Gundelfinger","full_name":"Gundelfinger, Eckart","first_name":"Eckart"},{"id":"353C1B58-F248-11E8-B48F-1D18A9856A87","first_name":"Peter M","last_name":"Jonas","full_name":"Peter Jonas","orcid":"0000-0001-5001-4804"},{"first_name":"Erwin","full_name":"Neher, Erwin","last_name":"Neher"},{"last_name":"Seeburg","full_name":"Seeburg, Peter","first_name":"Peter"}],"publist_id":"2394","extern":1,"citation":{"apa":"Frotscher, M., Gundelfinger, E., Jonas, P.

We studied the direct interference abilities of the invasive garden ant, Lasius neglectus VAN LOON, BOOMSMA & ANDRÁSFALVY, 1990, by performing one-to-one aggression tests of L. neglectus workers towards three native Lasius ant species that occur at the edge of a L. neglectus supercolony in Seva, Spain. Our results show that L. neglectus is highly aggressive against all three native Lasius species tested (L. grandis FOREL, 1909, L. emarginatus (OLIVIER, 1792), and L. cinereus SEIFERT, 1992), expressed as a higher attack rate of L. neglectus and behavioural dominance throughout the aggressive encounters. Attacks of L. neglectus were performed fastest and most frequent against L. grandis, and also the highest antennation frequencies were observed in encounters between these two species. This could be due to the largest difference in body size, or due to a greater overlap in ecological niche between L. neglectus and L. grandis compared to the other two native species. There was only weak support for L. neglectus workers from the periphery of the supercolony to be more aggressive relative to workers from the centre, even though the former encounter native ant species on a daily basis at the edge of the supercolony."}],"oa_version":"None","publisher":"Österreichische Gesellschaft für Entomofaunistik","month":"12","intvolume":" 9","year":"2006","publication_status":"published","day":"01","language":[{"iso":"eng"}],"publication":"Myrmecological News","page":"13 - 19","volume":9,"date_published":"2006-12-01T00:00:00Z","date_created":"2018-12-11T12:05:51Z","_id":"3912","type":"journal_article","status":"public","citation":{"mla":"Cremer, Sylvia, et al. “Attack of the Invasive Garden Ant: Aggression Behaviour of Lasius Neglectus (Hymenoptera: Formicidae) against Native Lasius Species in Spain.” Myrmecological News, vol. 9, Österreichische Gesellschaft für Entomofaunistik, 2006, pp. 13–19.","apa":"Cremer, S., Ugelvig, L.
