Different inhibitory synaptic input patterns in excitatory and inhibitory layer 4 neurons of ferret visual cortex.

The synaptic mechanisms underlying the generation of orientation and direction selectivity in layer 4 of the primary visual cortex are still largely unclear. Previous in vivo work has shown that intra-cortical inhibition plays a major role in generating the properties of orientation and direction selectivity. Excitatory and inhibitory cortical neurons differ in their receptive field properties:...

Recruitment of local inhibitory networks by horizontal connections in layer 2/3 of ferret visual cortex.

To investigate how neurons in cortical layer 2/3 integrate horizontal inputs arising from widely distributed sites, we combined intracellular recording and voltage-sensitive dye imaging to visualize the spatiotemporal dynamics of neuronal activity evoked by electrical stimulation of multiple sites in visual cortex. Individual stimuli evoked characteristic patterns of optical activity, while del...

Functional connectivity of disparity-tuned neurons in the visual cortex.

Different mechanisms have been proposed concerning how disparity-tuned neurons might be connected to produce the signals for depth perception. Here we present neurophysiological evidence providing insight on this issue. We have recorded simultaneously from pairs of disparity-tuned neurons in the cat's striate cortex. The purpose was to determine the relationships between disparity tuning and fu...

Layer-specific expression of multiple cadherins in the developing visual cortex (V1) of the ferret.

Cadherins are superfamily of Ca2+-dependent transmembrane glycoproteins with more than 100 members. They play a role in a wide variety of developmental mechanisms, including cell proliferation, cell differentiation, cell-cell recognition, neurite outgrowth and synaptogenesis. We cloned 16 novel members of the classic cadherin and delta-protocadherin subgroups from ferret brain. Their expression...

Cortico‐cortical connectivity within ferret auditory cortex

Despite numerous studies of auditory cortical processing in the ferret (Mustela putorius), very little is known about the connections between the different regions of the auditory cortex that have been characterized cytoarchitectonically and physiologically. We examined the distribution of retrograde and anterograde labeling after injecting tracers into one or more regions of ferret auditory co...
