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 ...
Invariant computations in local cortical networks with balanced excitation and inhibition
(Nature, 2005-06-23)
[Abstract] Cortical computations critically involve local neuronal circuits. The computations are often invariant across a cortical area yet are carried out by networks that can vary widely within an area according to its ...
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 ...
Foci of orientation plasticity in visual cortex
(Nature, 2001-05-03)
[Abstract] Cortical areas are generally assumed to be uniform in their capacity for adaptive changes or plasticity1, 2, 3, 4. Here we demonstrate, however, that neurons in the cat striate cortex (V1) show pronounced ...
Synaptic Integration by V1 Neurons Depends on Location Within the Orientation Map
(Elsevier/Cell Press, 2002)
[Abstract] Neurons in the primary visual cortex (V1) are organized
into an orientation map consisting of orientation domains arranged radially around “pinwheel centers” at
which the representations of all orientations ...
Combinación de nuevas técnicas electrofisiológicas y de imagen en el estudio de la función de la corteza visual primaria
(J. V. Sácnhez Andrés, 2003)
This work summarizes current research focused on explaining orientation selectivity of primary visual
cortex (V1), and describes the electrophysiological and imaging techniques than are being used. Development. The study ...
Specific roles of NMDA and AMPA receptors in direction-selective and spatial phase-selective responses in visual cortex
(Society of Neuroscience, 2001)
[Abstract] Cells in the superficial layers of primary visual cortex (area 17)
are distinguished by feedforward input from thalamic-recipient
layers and by massive recurrent excitatory connections be-
tween ...
