Computational neuroscientist Mark Humphries chats with Trey Elling about THE SPIKE: AN EPIC JOURNEY THROUGH THE BRAIN IN 2.1 SECONDS, including: an orchestra as an analogy for the cacophony of neural spikes, how rats' whiskers help us understand the accuracy of neural messaging, the value of dark neurons, frequency vs timing with spikes, the brain using past experiences to make decisions while the spike process is still going on, and more.
