Circuits and mechanisms for surround modulation in visual cortex

A Angelucci, M Bijanzadeh, L Nurminen… - Annual review of …, 2017 - annualreviews.org
Surround modulation (SM) is a fundamental property of sensory neurons in many species
and sensory modalities. SM is the ability of stimuli in the surround of a neuron's receptive …

Contribution of feedforward, lateral and feedback connections to the classical receptive field center and extra-classical receptive field surround of primate V1 neurons

A Angelucci, PC Bressloff - Progress in brain research, 2006 - Elsevier
A central question in visual neuroscience is what circuits generate the responses of neurons
in the primary visual cortex (V1). V1 neurons respond best to oriented stimuli of optimal size …

Toward an integration of deep learning and neuroscience

AH Marblestone, G Wayne, KP Kording - Frontiers in computational …, 2016 - frontiersin.org
Neuroscience has focused on the detailed implementation of computation, studying neural
codes, dynamics and circuits. In machine learning, however, artificial neural networks tend …

Top-down feedback controls spatial summation and response amplitude in primate visual cortex

L Nurminen, S Merlin, M Bijanzadeh, F Federer… - Nature …, 2018 - nature.com
Sensory information travels along feedforward connections through a hierarchy of cortical
areas, which, in turn, send feedback connections to lower-order areas. Feedback has been …

Inhibitory stabilization of the cortical network underlies visual surround suppression

H Ozeki, IM Finn, ES Schaffer, KD Miller, D Ferster - Neuron, 2009 - cell.com
In what regime does the cortical circuit operate? Our intracellular studies of surround
suppression in cat primary visual cortex (V1) provide strong evidence on this question …

GABA concentration is reduced in visual cortex in schizophrenia and correlates with orientation-specific surround suppression

JH Yoon, RJ Maddock, A Rokem, MA Silver… - Journal of …, 2010 - jneurosci.org
The neural mechanisms underlying cognitive deficits in schizophrenia remain essentially
unknown. The GABA hypothesis proposes that reduced neuronal GABA concentration and …

Space and time in visual context

O Schwartz, A Hsu, P Dayan - Nature Reviews Neuroscience, 2007 - nature.com
No sensory stimulus is an island unto itself; rather, it can only properly be interpreted in light
of the stimuli that surround it in space and time. This can result in entertaining illusions and …

Bottom-up dependent gating of frontal signals in early visual cortex

LB Ekstrom, PR Roelfsema, JT Arsenault… - Science, 2008 - science.org
The frontal eye field (FEF) is one of several cortical regions thought to modulate sensory
inputs. Moreover, several hypotheses suggest that the FEF can only modulate early visual …

Reconciling predictive coding and biased competition models of cortical function

MW Spratling - Frontiers in computational neuroscience, 2008 - frontiersin.org
A simple variation of the standard biased competition model is shown, via some trivial
mathematical manipulations, to be identical to predictive coding. Specifically, it is shown that …

Receptive‐field properties of V1 and V2 neurons in mice and macaque monkeys

G Van den Bergh, B Zhang, L Arckens… - Journal of …, 2010 - Wiley Online Library
We report the results of extracellular single‐unit recording experiments where we
quantitatively analyzed the receptive‐field (RF) properties of neurons in V1 and an adjacent …
