Principal Investigator: Baldwin Goodell

Gray Matter Research focuses on Microdrive Systems and Recording Chamber Systems. For the BRAIN Initiative, Goodell and his colleagues aim to develop optrodes, which are implantable columns of lights and wires for simultaneous electrical recording of neurons and delivery of light flashes to multiple brain areas.

Example data collected from 4 electrodes during a single recording session. A: short epoch of raw data sampled from 4 electrodes in area 7a of the posterior parietal cortex of an alert monkey. The signals are broadband (1 Hz to 10 kHz). Extracellular action potentials are visible as negative going spikes in the signals. B: plot of 1,000 superimposed waveforms extracted from the high-pass filtered signal on channel 3. The high-amplitude waveforms reveal a single unit that is well separated from the lower amplitude multiunit activity.

Project Description

In order to gain a greater understanding of the neural mechanisms that mediate human cognitive function new approaches and technologies are needed to dramatically expand the ability to record and manipulate the activity of large numbers of neurons throughout widespread areas of the primate brain. Over the past 5-10 years, our groups have made two major ...
