Brain Bee Study Guide Apr 2026

You are about to initiate movement. The EPSP travels down your dendrites, summing at the axon hillock — your decision zone. Here, voltage-gated sodium channels wait. The membrane potential crosses threshold (-55 mV from resting -70 mV). Bang.

A volley of signals races up through the of the thalamus. And then — you feel it. A massive excitatory postsynaptic potential (EPSP) arrives at your basal dendrites. brain bee study guide

The hose is open.
