1. To test the mode of functional connectivity in the basal ganglia circuitry, we studied the
activity of simultaneously recorded neurons in the globus pallidus (GP) of a behaving rhesus …

A novel method of chronic optical imaging based on new voltage-sensitive dyes (VSDs)
was developed to facilitate the explorations of the spatial and temporal patterns underlying …

There are two views as to the character of basal-ganglia processing – processing by
segregated parallel circuits or by information sharing. To distinguish between these views, we …

Spatiotemporal structure of cortical activity: properties and behavioral relevance. J. …

The neuronal mechanisms underlying perceptual grouping of discrete, similarly oriented
elements are not well understood. To investigate this, we measured neural population …

The ultimate goal of high-resolution functional brain mapping is single-condition (stimulus
versus no-stimulus maps) rather than differential imaging (comparing two "stimulus maps"), …

Explorations of learning and memory, other long-term plastic changes, and additional cognitive
functions in the behaving primate brain would greatly benefit from the ability to image the …

We present a transparentsilicone dural substitute, which we have been using for the last 7
years for imaging cortical dynamics in awake behaving monkeys. This substitute enabled us …

The frontal eye field and neighboring area 8Ar of the primate cortex are involved in programming
and execution of saccades. Electrical microstimulation in these regions elicits short-…

Visual processing shows a highly distributed organization in which the presentation of a
visual stimulus simultaneously activates neurons in multiple columns across several cortical …
