Local networks in visual cortex and their influence on neuronal responses and dynamics
(Elsevier, 2005-11-07)[Abstract] Networks of neurons in the cerebral cortex generate complex outputs that are not simply predicted by their inputs. These emergent responses underlie the function of the cortex. Understanding how cortical networks ... -
Cortical modulation of dorsal column nuclei: a computational study
(Springer, 2006-04-22)[Abstract] We present a computational study aimed at exploring the sensorimotor cortex modulation of the behaviour of dorsal column nuclei, specifically the impact of synaptic parameters, during both sleep and waking ... -
The operating regime of local computations in primary visual cortex
(Oxford University Press, 2009-02-16)[Abstract] In V1, local circuitry depends on the position in the orientation map: close to pinwheel centers, recurrent inputs show variable orientation preferences; within iso-orientation domains, inputs are relatively ... -
Spatial frequency tuning of orientation-discontinuity-sensitive corticofugal feedback to the cat lateral geniculate nucleus
(Wiley, 1996-01-15)[Abstract] 1. The influence of spatial frequency on the inhibitory component of the effects mediated by feedback from the visual cortex has been examined in X and Y cells in the A laminae of the feline dorsal lateral ... -
Responses of primate LGN cells to moving stimuli involve a constant background modulation by feedback from area MT
(Elsevier, 2013-05-03)[Abstract] The feedback connections from the cortical middle temporal (MT) motion area, to layer 6 of the primary visual cortex (V1), have the capacity to drive a cascaded feedback influence from the layer 6 cortico-geniculate ...
