Development of tube tetrodes and a multi-tetrode drive for deep structure electrophysiological recordings in the macaque brain.

Highlights: [•] Developed new stiffer tube tetrodes for deep brain electrophysiology. [•] Protocol for constructing tube tetrodes with standard laboratory tools. [•] Developed a microdrive for advancing these tube tetrodes in macaque brain. [•] Conducted electrophysiology with tube tetrodes in the inferotemporal cortex. [•] Multiple single units can be recorded with tube tetrodes. [Copyright &y& Elsevier]
