Optogenetic vision restoration with high resolution
Ulisse Ferrari, Stéphane Deny, Abhishek Sengupta +6
The majority of inherited retinal degenerations are due to photoreceptor cell death. In many cases ganglion cells are spared making it possible to stimulate them to restore visual…
Modeling the correlated activity of neural populations: A review
Christophe Gardella, Olivier Marre, Thierry Mora
The principles of neural encoding and computations are inherently collective and usually involve large populations of interacting neurons with highly correlated activities. While t…
Separating intrinsic interactions from extrinsic correlations in a network of sensory neurons
Ulisse Ferrari, Stephane Deny, Matthew Chalk +3
Correlations in sensory neural networks have both extrinsic and intrinsic origins. Extrinsic or stimulus correlations arise from shared inputs to the network, and thus depend stron…
A simple model for low variability in neural spike trains
Ulisse Ferrari, Stephane Deny, Olivier Marre +1
Neural noise sets a limit to information transmission in sensory systems. In several areas, the spiking response (to a repeated stimulus) has shown a higher degree of regularity th…
Maximum entropy models reveal the excitatory and inhibitory correlation structures in cortical neuronal activity
Trang-Anh Nghiem, Bartosz Telenczuk, Olivier Marre +2
Maximum Entropy models can be inferred from large data-sets to uncover how collective dynamics emerge from local interactions. Here, such models are employed to investigate neurons…
