I designed, created, troubleshot, and tested a chronically mounted in vivo recording device helmet for
monitoring neurons in the rat hippocampus. It had electronically controlled 0.5μm depth resolution (a 200x
improvement) with each of the 8 groups of 4 recording electrodes (tetrodes), Matlab desktop GUI controls, 3-D printed housing and custom printed circuit boards to control the motors and to record the data from the
tetrodes. As part of this project, I planned, built, and tested a weaving loom for the braiding of the many fine and long wires for used brain recordings. Wires will twist and break normally, while my wire braid mitigated much of the breakage issues.
