How to Measure Electrode Impedance on the Bench

Impedance is the opposition to electrical current in a circuit, and in brain electrodes, it matters because high impedance can reduce signal quality, leading to poor detection of neural activity or inefficient stimulation delivery.

An Unofficial FED Cleaning Protocol

FED failures can be traced to IR sensor and circuit board issues, which can be remediated with an isopropyl wash.

GR/PR: An open-source grip strength meter

Helical electrodes for electrophysiology in wild animals

In applications where electrodes are being routed or weaved—especially if the animal will undergo full recovery and resume normal behavior (like in a wild or free-ranging animal)—lead flexibility is going to be critical to the endurance and quality of the electrophysiological recordings.
