Cat and monkey V1 neurons : comparison of the responses to sustained and transiently presented stimuli
… the examination of the response properties of neurons in the primary visual cortices (V1) of cats and monkeys have employed extended presentations of luminance modulated sinusoidal grating patterns or spatiotemporal noise (lasting on the order of several seconds) that are designed to obtain the …

Influence of the structure of the orientation preference map on the responses of V1 neurons
… majority of inputs to primary visual cortex (V1) neurons arise from the dense local projections of neighboring neurons. Although several proposals have been made, it is not known what role these connections play in shaping the response properties of V1 neurons. It was reasoned that the …

Dynamic and Integrative Properties of the Primary Visual Cortex
… these processes in the primary visual cortex (V1), where neurons have been proposed to integrate visual inputs along a geometric pattern known as the association field (AF). We first used cortical reorganization as a model to investigate the role that a specific network of V1 connections, the …

Top-Down Control of Lateral Interactions in Visual Cortex
<p>V1 neurons are capable of integrating information over a large area of visual field. Their responses to local features are dependent on the global characteristics of contours and surfaces that extend well beyond their receptive fields. These contextual influences in V1 are subject to cognitive …

Highly Selective Attentional Modulation of Task-Appropriate Neural Populations in Primary Visual Cortex
… are only present within task-appropriate neurons or neuron groups, and it is the location (and not nature) of these modulations which defines the observer’s current attentive state. We present the results of two orthogonal attention tasks, both targeting distinct but specific and well …

Sensorimotor transformation and information coding across cortex during perceptual decisions
… outputs? We investigated the roles of visual (V1), posterior parietal (PPC), and frontal motor (fMC) cortices of mice during a memory-guided visual decision task. Large-scale calcium imaging revealed that neurons in each area were heterogeneous and spanned all task epochs (stimulus, delay, …

The mechanisms of reliable coding in mouse visual cortex
… are constantly bombarded with information. Neurons in the visual cortex have to transform these complex inputs into robust and parsimonious neural codes that effectively guide behavior. The ability of neurons to efficiently convey information is, however, limited by intrinsic and shared …
