Normalization of cell responses in cat striate cortexAbstract Simple cells in the striate cortex have been depicted as half-wave-rectified linear operators. Complex cells have been depicted as energy mechanisms, constructed from the squared sum of the outputs of quadrature pairs of linear operators. However, the linear/energy model falls short of a complete explanation of striate cell responses. In this paper, a modif... ...

A psychophysically motivated model for two-dimensional motion perceptionAbstract A quantitative model is developed to predict the perceived direction of moving two-dimensional patterns. The model incorporates both a simple motion energy pathway and a “texture boundary motion” pathway that incorporates response squaring before the extraction of motion energy. These pathways correspond to Fourier and non-Fourier motion pathways and are hy... ...

Push–pull model of the primate photopic electroretinogram: A role for hyperpolarizing neurons in shaping the b-waveAbstract Existing models of the primate photopic electroretinogram (ERG) attribute the light-adapted b –wave to activity of depolarizing bipolar cells (DBCs), mediated through a release of potassium that is monitored by Müller cells. However, possible ERG contributions from OFF-bipolar cells (HBCs) and horizontal cells (HzCs) have not been ... ...

Response linearity and kinetics of the cat retina: The bipolar cell component of the dark-adapted electroretinogramAbstract The electroretinogram (ERG) of the dark-adapted cat eye in response to brief ganzfeld flashes of a wide range of intensities was recorded after intravitreal injection of n-methyl dl aspartate (NMdlA, cumulative intravitreal concentration of 1.3–3.9 mM) to suppress inner-retinal components, and after intravitreal dl or L-2-amino-4-phosphonobutyric acid (dl-A... ...

Visual response latencies of magnocellular and parvocellular LGN neurons in macaque monkeysSignals relayed through the magnocellular layers
of the LGN travel on axons with faster conduction speeds
than those relayed through the parvocellular layers. As
a result, magnocellular signals might reach cerebral cortex
appreciably before parvocellular signals. The relative
speed of these two channels cannot be accurately predicted
based solely on axon conduction speeds, however. O... ...

Calbindin and calretinin localization in retina from different speciesAbstract Calbindin-D28K and calretinin are homologous calcium-binding proteins localized in many neurons of the central nervous system. We have compared polyclonal antibodies against calbindin and calretinin and have shown by western blots using purified calbindin and calretinin from rat that (1) anti-calretinin does not recognize calbindin and (2) anti-calbindin pr... ...

The use of m-sequences in the analysis of visual neurons: Linear receptive field propertiesAbstract We have used Sutter's (1987) spatiotemporal m-sequence method to map the receptive fields of neurons in the visual system of the cat. The stimulus consisted of a grid of 16 X 16 square regions, each of which was modulated in time by a pseudorandom binary signal, known as an m-sequence. Several strategies for displaying the m-sequence stimulus are presented.... ...

Spatial and temporal coherence in cortico-cortical connections: A cross-correlation study in areas 17 and 18 in the catAbstract Visual cortical areas are richly but selectively connected by “patchy” projections. We characterized these connections physiologically with cross-correlograms (CCHs), calculated for neuron pairs or small groups located one each in visual areas 17 and 18 of the cat. The CCHs were then compared to the visuotopic and orientation match of the neurons' receptive... ...

Dual response modes in lateral geniculate neurons: Mechanisms and functionsAbstract Relay cells of the lateral geniculate nucleus, like those of other thalamic nuclei, manifest two distinct response modes, and these represent two very different forms of relay of information to cortex. When relatively hyperpolarized, these relay cells respond with a low threshold Ca2+ spike that triggers a brief burst of conventional ac... ...

Independence and merger of thalamocortical channels within macaque monkey primary visual cortex: Anatomy of interlaminar projectionsAbstract An important issue in understanding the function of primary visual cortex in the macaque monkey is how the several efferent neuron groups projecting to extrastriate cortex acquire their different response properties. To assist our understanding of this issue, we have compared the anatomical distribution of VI intrinsic relays that carry information derived ... ...
