A Neuron Is a Decision Point, Not a Wire

A neuron is an active decision point, not a passive wire. Professor Mechanism and Professor Method trace a signal from dendrites through membrane potential, threshold, action potential, axon, and synapse while showing why every link is also a measurement problem.
The episode reconnects Week 1's nervous-system map to cellular signaling and asks what a behavioral response, reaction time, or physiological signal can actually reveal about the underlying mechanism.
Learning goals:
• Explain how neurons integrate inputs and reach threshold.
• Connect action potentials and synapses to observable behavior.
• Separate a neural mechanism from the measurement used to infer it.
• Identify alternative explanations for an observed response.
