Instantaneous correlation of excitation and inhibition during ongoing and sensory-evoked activities
M Okun, I Lampl - Nature neuroscience, 2008 - nature.com
Temporal and quantitative relations between excitatory and inhibitory inputs in the cortex are
central to its activity, yet they remain poorly understood. In particular, a controversy exists …

Synfire chains and cortical songs: temporal modules of cortical activity
How can neural activity propagate through cortical networks built with weak, stochastic
synapses? We find precise repetitions of spontaneous patterns of synaptic inputs in neocortical …

[HTML][HTML] Local and thalamic origins of correlated ongoing and sensory-evoked cortical activities
…, B Mohar, AN Rappaport, I Lampl - Nature …, 2016 - nature.com
Thalamic inputs of cells in sensory cortices are outnumbered by local connections. Thus, it
was suggested that robust sensory response in layer 4 emerges due to synchronized …

Intracellular measurements of spatial integration and the MAX operation in complex cells of the cat primary visual cortex
We have examined the spatial integration properties of complex cells to determine whether
some of their responses can be described by a maximum operation (MAX)-like computation, …
