A Refined Neuronal Population Measure of Visual Attention.
(PloS one, 2015-01)Neurophysiological studies of cognitive mechanisms such as visual attention typically ignore trial-by-trial variability and instead report mean differences averaged across many trials. Advances in electrophysiology allow ... -
A screw microdrive for adjustable chronic unit recording in monkeys.
(J Neurosci Methods, 1998-06-01)A screw microdrive is described that attaches to the grid system used for recording single neurons from brains of awake behaving monkeys. Multiple screwdrives can be mounted on a grid over a single cranial opening. This ... -
Building an organic computing device with multiple interconnected brains.
(Scientific reports, 2015-07-09)Recently, we proposed that Brainets, i.e. networks formed by multiple animal brains, cooperating and exchanging information in real time through direct brain-to-brain interfaces, could provide the core of a new type of computing ... -
Design and in vivo evaluation of more efficient and selective deep brain stimulation electrodes.
(Journal of neural engineering, 2015-08)<h4>Objective</h4>Deep brain stimulation (DBS) is an effective treatment for movement disorders and a promising therapy for treating epilepsy and psychiatric disorders. Despite its clinical success, the efficiency and selectivity ... -
Effects of Electrical Stimulation in the Inferior Colliculus on Frequency Discrimination by Rhesus Monkeys and Implications for the Auditory Midbrain Implant.
(The Journal of neuroscience : the official journal of the Society for Neuroscience, 2016-05)Understanding the relationship between the auditory selectivity of neurons and their contribution to perception is critical to the design of effective auditory brain prosthetics. These prosthetics seek to mimic natural activity ... -
Evaluation and resolution of many challenges of neural spike sorting: a new sorter.
(Journal of neurophysiology, 2021-12)We evaluate existing spike sorters and present a new one that resolves many sorting challenges. The new sorter, called "full binary pursuit" or FBP, comprises multiple steps. First, it thresholds and clusters to identify ... -
Frontal eye field neurons orthodromically activated from the superior colliculus.
(J Neurophysiol, 1998-12)Frontal eye field neurons orthodromically activated from the superior colliculus. J. Neurophysiol. 80: 3331-3333, 1998. Anatomical studies have shown that the frontal eye field (FEF) and superior colliculus (SC) of monkeys ... -
Multielectrode evidence for spreading activity across the superior colliculus movement map.
(J Neurophysiol, 2000-07)The monkey superior colliculus (SC) has maps for both visual input and movement output in the superficial and intermediate layers, respectively, and activity on these maps is generally related to visual stimuli only in one ... -
Single neurons may encode simultaneous stimuli by switching between activity patterns.
(Nature communications, 2018-07-13)How the brain preserves information about multiple simultaneous items is poorly understood. We report that single neurons can represent multiple stimuli by interleaving signals across time. We record single units in an auditory ... -
Stimulation Efficiency With Decaying Exponential Waveforms in a Wirelessly Powered Switched-Capacitor Discharge Stimulation System.
(IEEE transactions on bio-medical engineering, 2018-05)The purpose of this study was to test the feasibility of using a switched-capacitor discharge stimulation (SCDS) system for electrical stimulation, and, subsequently, determine the overall energy saved compared to a conventional ...
