Neurons in the lateral geniculate nucleus (LGN) of the thalamus produce spikes that can be
classified as burst spikes and tonic spikes. Although burst spikes are generally associated …

The response of a neuron in striate cortex to an optimally oriented stimulus is suppressed by
a superimposed orthogonal stimulus. The neural mechanism underlying this cross …

Responses of 71 cells in areas 17 and 18 of the cat visual cortex were recorded
extracellularly while stimulating with gratings drifting in each direction across the receptive …

In the motion-extrapolation hypothesis, the visual system can extrapolate the instantaneous
position of a moving object from its past trajectory. The existence of such a mechanism in …

Thalamic neurons respond to visual scenes by generating synchronous spike trains on the
timescale of 10–20 ms that are very effective at driving cortical targets. Here we demonstrate …

We used two-dimensional (2-D) sparse noise to map simultaneous and sequential two-spot
interactions in simple and complex direction-selective cells in macaque V1. Sequential …

Synapses made by local interneurons dominate the intrinsic circuitry of the mammalian
visual thalamus and influence all signals traveling from the eye to cortex. Here we draw on …

To investigate the contribution of parietal cortex to perceptual decisions, we trained monkeys
on a perceptual decision task that allowed simultaneous experimental control over how …

Based on extracellular recordings from 69 lateral geniculate nucleus (LGN) cells in the
anesthetized cat, we found spatial summation within their receptive fields to be dependent …

Viswanathan and Freeman1 claim that oxygen concentration and, by inference, blood
oxygen level–dependent (BOLD) functional magnetic resonance imaging (fMRI) reflect …
