Quick questions on Neurotransmitters glutamate and GABA: VCE Psychology Unit 3
2short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is glutamate?Show answer
Glutamate is the brain's primary excitatory neurotransmitter. When it binds to a postsynaptic receptor it increases the likelihood that the neuron will fire.
What is gABA?Show answer
GABA (gamma-aminobutyric acid) is the brain's primary inhibitory neurotransmitter. When it binds to a postsynaptic receptor it makes that neuron less likely to fire, so its role is to regulate postsynaptic activation and keep neural activity from spiralling out of control.
