Neurons in primary visual cortex exhibit well documented centre–surround receptive field
organization, whereby the centre is dominated by excitatory influences and the surround is …

A few distinct cortical operations have been postulated over the past few years, suggested
by experimental data on nonlinear neural response across different areas in the cortex …

Changing gain in a neuronal system has important functional consequences, but the
underlying mechanisms have been elusive. Models have suggested a variety of neuronal …

Orientation selectivity is an important emergent property of neurons in the primary visual
cortex, and inhibition is thought to play an important role in establishing this selectivity. But …

Large-field visual motion elicits tracking eye movements at ultra-short latency, often termed
ocular following responses (OFRs). We recorded the initial OFRs of three human subjects …

Neurons in the visual cortex receive a large amount of input from recurrent connections, yet
the functional role of these connections remains unclear. Here we explore networks with …

What patterns of synaptic input cause cortical neurons to fire action potentials? Are they
stochastic in nature, or do action potentials arise from the specific timing of synaptic input …

In spatial working memory tasks, pyramidal cells in the relevant cortical circuit receive
massive inputs to shape stimulus location-selective sustained activity. A significant part of …

Contextual modulation is a universal phenomenon in the primary visual cortex (V1). It is
often allocated to the two categories of suppression and facilitation, which are either …
