Correlated neuronal discharge rate and its implications for psychophysical performance
Pooling responses across neurons should average out noise in the activity of single cells, leading to substantially improved psychophysical performance. Expand
The Variable Discharge of Cortical Neurons: Implications for Connectivity, Computation, and Information Coding
Cortical neurons exhibit tremendous variability in the number and temporal distribution of spikes in their discharge patterns. Furthermore, this variability appears to be conserved over large regionsExpand
A relationship between behavioral choice and the visual responses of neurons in macaque MT.
We have previously documented the exquisite motion sensitivity of neurons in extrastriate area MT by studying the relationship between their responses and the direction and strength of visual motionExpand
The visual field representation in striate cortex of the macaque monkey: Asymmetries, anisotropies, and individual variability
The topographic organization of striate cortex in the macaque was studied using physiological recording techniques. Results were displayed on two-dimensional maps of the cortex, which facilitated theExpand
A computational analysis of the relationship between neuronal and behavioral responses to visual motion
We have documented previously a close relationship between neuronal activity in the middle temporal visual area (MT or V5) and behavioral judgments of motion (Newsome et al., 1989; Salzman et al.,Expand
Context-dependent computation by recurrent dynamics in prefrontal cortex
Prefrontal cortex is thought to have a fundamental role in flexible, context-dependent behaviour, but the exact nature of the computations underlying this role remains largely unknown. In particular,Expand
Stimulus onset quenches neural variability: a widespread cortical phenomenon
Neural responses are typically characterized by computing the mean firing rate, but response variability can exist across trials. Many studies have examined the effect of a stimulus on the meanExpand
Correlated Firing in Macaque Visual Area MT: Time Scales and Relationship to Behavior
We studied the simultaneous activity of pairs of neurons recorded with a single electrode in visual cortical area MT while monkeys performed a direction discrimination task. Previously, we reportedExpand
Matching Behavior and the Representation of Value in the Parietal Cortex
Psychologists and economists have long appreciated the contribution of reward history and expectation to decision-making. Yet we know little about how specific histories of choice and reward lead toExpand
