From ion gradients to memory, one short piece at a time
This course follows the nervous system from the biophysics of a single membrane to the systems that produce behaviour. It covers how neurons hold a resting voltage, fire, and signal to one another; how each sense converts physical or chemical energy into a neural code and maps it onto the brain; how movement is organised from reflex to cortex; how hormones and modulatory systems set the gain on motivation and emotion; and how activity reshapes synapses during development and learning. We compress the ground a full textbook covers and reorganise it into short, self-contained pieces, so you can work through the mechanism you need without reading a chapter around it. By the end you can trace a stimulus into a spike train, follow it to the cortex, and say what a described deficit tells you about the circuit behind it.

“A patient, diagram-driven route from membrane voltage to memory.”
The sequence never asks you to take a mechanism on authority: each claim arrives with the evidence that produced it, and the clinical asides keep the abstraction anchored. It is a demanding course, but the short format means you can absorb it in the order your curiosity dictates.
Nano College writes university-level courses in short, self-contained pieces designed to be finished — not shelved. Every collection is original: written to cover the ground a full course covers, with the same rigour, in a format that fits the way people actually learn today.
