Weinberger Department of Psychobiology and Center for the Neurobiology of Learning and Memory, University of California, Irvine, California 92717-3800 KEY WORDS: deafferentation, learning, auditory, somatosensory, visual INTRODUCTION A dominant belief in neuroscience is that sensory systems in the adult …
The receptive field of an individual sensory neuron is the particular region of the sensory space (e.g., the body surface, or the visual field) in which a stimulus will modify the firing of that neuron.
T he Visual Cortex The primary visual cortex lies in the fold of the calcarine sulcus. The fovea is represented at the posterior end of the calcarine sulcus. This small part of the retina has an expanded representation, which occupies about half of the primary visual cortex. The remaining peripheral retina is represented at the anterior half.

The receptive field size of neurons in primary visual cortex is larger than the ones in the retina and LGN and can typically encompass about 1 degree of visual angle.

In primary visual cortex, neurons are classified into simple cells and complex cells based on their response properties. Although the role of these two cell types in vision is still unknown, an attractive hypothesis is that simple cells are necessary to construct complex receptive fields.
Furthermore, the assembly of contours and surfaces into unified percepts was assumed to take place at high levels in the visual pathway, whereas the receptive fields of cells in primary visual cortex represented very small windows on the visual scene.

A simple cell in the primary visual cortex is a cell that responds primarily to oriented edges and gratings (bars of particular orientations). These cells were discovered by Torsten Wiesel and David Hubel in the late 1950s.
Since motion in our visual field is continuous, the signals received by the visual system contain an abundance of transient components in the contrast domain. Here using a modified reverse correlation method, we studied the properties of responses of neurons in the cat primary visual cortex to different contrasts of grating stimuli presented statically and transiently for 40 ms, and showed
of neuronal plasticity in adult visual cortex over a wide range of time scales, ranging from minutes to months. As with the other systems, one can also induce plasticity in the visual system with peripheral lesions. Focal retinal lesions, induced with lasers, lead over a period of months to a shrinkage in the cortical representation of the lesioned part of the retina and an increase in the

of signal processing occurs within primary visual cortex. We postulate that the use of natural image sequences may reveal aspects of cortical processing that are not evident when using simpler stimuli such as bars and luminance modulated gratings. Because the cortex is a nonlinear network, it may not be feasi-ble to use the neural responses to simple stimuli to predict and understand cortical

We studied changes in the spatial parameters of receptive fields (RFs) of visually sensitive neurons in the associative area 21a of the cat cortex under conditions of presentation of moving visual stimuli. The results of experiments demonstrated that these parameters are dynamic and depend, from
The response of a neuron in primary visual cortex (V1) to an optimal stimulus in its classical receptive field (CRF) can be reduced by the presence of an orthogonal mask, a phenomenon known as cross-orientation suppression. The presence of a parallel stimulus outside the CRF can have a similar
In the visual cortex little is known about the effect of dark adaptation on receptive field properties of cells. Two studies in cats have looked at the effects of dark adaptation on orientation selectivity in V-1: both found a persistence of orientation tuning ( Bisti, Clement, Maffei and Mecacci, 1977 ; Ramoa, Freeman and Macy, 1985 ).
The functional properties and structure of receptive fields in primary visual cortical (V1) neurons represent how visual information is processed in the mammalian neocortex.

Receptive fields of neurons in the primary visual cortex typically consist of an elongated excitatory field center that determines the orientation specificity of the neuron. The neuron is most strongly activated by light falling on the receptive field center without extending on the inhibitory surround.
The study was performed on neurons with direction selective (DS) receptive fields (RFs) in the primary visual cortex of the cat. Preferred directions (PDs) of these cells to a single light spot and a system of two identical light spots moving across the RF with a given angle between them were compared.

Feedback of this sort can allow rapid, experience-dependent changes in gain control and receptive field dynamics of the more peripheral structure, which in turn can influence subsequent cortical receptive fields [e.g. the visual system (Murphy and Sillito, 1987; Cudeiro et al., 2000)]. The second major similarity between the olfactory cortex and thalamocortical systems is the presence of
1. Cells in area 17 of the cat visual cortex were studied with a view towards correlating receptive field properties with layering.

Nearly 40 years ago, in the pages of this journal, Hubel and Wiesel provided the first description of receptive fields in the primary visual cortex of higher mammals. They defined two classes of cortical cells, ‘simple’ and ‘complex’, based on neural responses to simple visual stimuli. The

Abstract. Neurons in primary visual cortex (area 17) respond vigorously to oriented stimuli within their receptive fields; however, stimuli presented outside the suprathreshold receptive field can also influence their responses.
In primary visual cortex, neurons are classified into simple cells and complex cells based on their response properties. Although the role of these two cell types in vision is still unknown, an attractive hypothesis is that simple cells are necessary to construct complex receptive fields.
Feedback of this sort can allow rapid, experience-dependent changes in gain control and receptive field dynamics of the more peripheral structure, which in turn can influence subsequent cortical receptive fields [e.g. the visual system (Murphy and Sillito, 1987; Cudeiro et al., 2000)]. The second major similarity between the olfactory cortex and thalamocortical systems is the presence of

In the visual cortex little is known about the effect of dark adaptation on receptive field properties of cells. Two studies in cats have looked at the effects of dark adaptation on orientation selectivity in V-1: both found a persistence of orientation tuning ( Bisti, Clement, Maffei and Mecacci, 1977 ; Ramoa, Freeman and Macy, 1985 ).
Receptive fields of neurons in the primary visual cortex typically consist of an elongated excitatory field center that determines the orientation specificity of the neuron. The neuron is most strongly activated by light falling on the receptive field center without extending on the inhibitory surround.
