C2.2.13 (HL)—Inhibitory neurotransmitters Topic Practice
C2.2.13 (HL)—Inhibitory neurotransmitters Topic Practice
Students practise explaining how inhibitory neurotransmitters reduce neuronal excitability by altering ion channel activity and membrane potential.
How this is tested
- explain how GABA-induced Cl⁻ influx hyperpolarises a postsynaptic neuron
- link K⁺ efflux via inhibitory neurotransmitters to increased threshold for action potential generation
