Temporal structure in neuronal activity during working memory in Macaque parietal cortex
Bijan Pesaran,John S. Pezaris,John S. Pezaris,Maneesh Sahani,Partha P. Mitra,Richard A. Andersen +5 more
TL;DR: In this article, the temporal structure of single unit (SU) activity and simultaneously recorded local field potential (LFP) activity from area LIP in the inferior parietal lobe of two awake macaques during a memory-saccade task were investigated.

Temporal structure in neuronal activity during working memory in macaque parietal cortex
Bijan Pesaran,John S. Pezaris,John S. Pezaris,Maneesh Sahani,Partha P. Mitra,Richard A. Andersen +5 more
TL;DR: The temporal structure of local field potential activity and spiking from area LIP in two awake macaques during a memory-saccade task was studied and it was found that LFP activity in parietal cortex discriminated between preferred and anti-preferred direction with approximately the same accuracy as the spike rate.
Journal ArticleDOI
Demonstration of artificial visual percepts generated through thalamic microstimulation
John S. Pezaris,R. Clay Reid +1 more
TL;DR: It is shown that microstimulation of the dorsal lateral geniculate nucleus of the thalamus can generate localized visual percepts in alert monkeys, and that this technique may be useful for a visual prosthesis.
Journal ArticleDOI
Getting signals into the brain: visual prosthetics through thalamic microstimulation
John S. Pezaris,Emad N. Eskandar +1 more
TL;DR: The authors review the potential locations for stimulation electrode placement for visual prostheses, assessing the anatomical and functional advantages and disadvantages of each and proposing the visual prosthesis as a model for a general high-fidelity machine-brain interface.
Journal ArticleDOI
The spatial receptive field of thalamic inputs to single cortical simple cells revealed by the interaction of visual and electrical stimulation
TL;DR: With moderate currents, cortical spikes were evoked with low to moderate probability and their occurrence was modulated by ongoing sensory (visual) input and the effectiveness of an extracellular method of measuring subthreshold afferent input to cortex is demonstrated.
