In Episode #83, Jesse — following up on his long-ago “Aniracetam self-experiment” episode — calls in some scientific muscle and is joined by Professor Keith Wesnes. Over a career spanning more than four decades, Professor Wesnes has founded one of the world’s leading companies for testing cognitive function and has been responsible for almost 200 clinical trials — including Aniracetam tests for its original European manufacturer.

In This Week In Neuroscience, we learn how a recent study on mice has led researchers to find how the brain deciphers movement, speed, and spatial mapping. (Do mice have an internal “speed limit”? A small group of cells near the hippocampus seems to say: Yes.)

Aniracetam fan? You’re not alone. Aniracetam is the compound at the heart of NEXUS, the flagship cognitive stack from Axon Labs.
