Neurotransmission: The Language of Neurons

# 🎧 **PSYC UNIT 2 — CHAPTER 1: Neurotransmission** --- ## **Introduction — Where Electricity

Meets Chemistry** Imagine for a moment that your brain is a vast city at night.

Billions of lights flicker on and off, each representing a neuron communicating with thousands of

others. Some roads are bright and busy; others are dim backstreets. Every second,

this network sends signals that let you breathe, move, feel joy,

Inside each neuron, information travels as an **electrical impulse**, a quick wave of
