Dynamics of extraclassical surround modulation in three types of V1 neurons.
Visual stimuli outside of the classical receptive field (CRF) can influence the response of neurons in primary visual cortex (V1). While recording single units in cat, we presented drifting sinusoidal gratings in circular apertures of different sizes to investigate this extraclassical surround modulation over time. For the full 2-s stimulus time course, three types of neurons were found: 1) 68%...
متن کاملExtraclassical Responses in V1 Modeled via Modulated Cortical Conductances
Two competing phenomological models of extraclassical spatial summation in V1 are the Differenceof-Gaussians (DoG) and the Ratio-of-Gaussians (RoG) which argue for subtractive or divisive normalization, respectively, as the basis for a variety of extraclassical response properties, such as surround suppression and contrast-dependent receptive field growth. Problematic with these models, however...
متن کاملOrigin and Dynamics of Extraclassical Suppression in the Lateral Geniculate Nucleus of the Macaque Monkey
In addition to the classical, center/surround receptive field of neurons in the lateral geniculate nucleus (LGN), there is an extraclassical, nonlinear surround that can strongly suppress LGN responses. This form of suppression likely plays an important role in adjusting the gain of LGN responses to visual stimuli. We performed experiments in alert and anesthetized macaque monkies to quantify e...
متن کاملDependence of response properties on sparse connectivity in a spiking neuron model of the lateral geniculate nucleus.
We present a large-scale anatomically constrained spiking neuron model of the lateral geniculate nucleus (LGN), which operates solely with retinal input, relay cells, and interneurons. We show that interneuron inhibition and sparse connectivity between LGN cells could be key factors for explaining a number of observed classical and extraclassical response properties in LGN of monkey and cat. Am...
متن کاملRetinal and Nonretinal Contributions to Extraclassical Surround Suppression in the Lateral Geniculate Nucleus.
Extraclassical surround suppression is a prominent receptive field property of neurons in the lateral geniculate nucleus (LGN) of the dorsal thalamus, influencing stimulus size tuning, response gain control, and temporal features of visual responses. Despite evidence for the involvement of both retinal and nonretinal circuits in the generation of extraclassical suppression, we lack an understan...
