What’s covered in this cheat sheet
This infographic covers the core content of Unit 1: the nature-nurture interaction; the central and peripheral nervous systems (somatic, autonomic, sympathetic, parasympathetic); neuron anatomy and the action potential; how neurotransmitters work at the synapse; key neurotransmitters (dopamine, serotonin, GABA, acetylcholine); major brain structures (frontal lobe, hippocampus, amygdala, hypothalamus, cerebellum, thalamus); brain plasticity; sleep stages (NREM 1-3 and REM) and circadian rhythms; and the basics of sensation — transduction, absolute threshold, and sensory adaptation.
