Design and Assembly of a Lightweight, Multi-Cannula Tetrode Drive for Bilateral Hippocampal and ACC Recordings

Implants and Electrophysiology: Electrophysiology is the study of the electrical properties of cells and tissues, neuronal implants enable high-resolution recordings of neuron action potentials and their locations in the brain. Data gathered is key in investigating/mapping cognition and effects of neurological pathologies on regular neural systems. Hyperdrive Model: Previous model was restricted to two implant sites, and displayed frequent tetrode deformation Hyperdrive was modified to support four implant sites and 16 independently movable tetrodes using 3D modeling software, while keeping its weight below 1.5 grams. Targets: Researchers targeted the hippocampus (CA1, CA3) and ACC, using the novel bilateral model
