Q

Neurochemistry

A

Neurotransmitters- chemicals found within the brain, each have a different effect on the brain
Excitatory- make the brain more active
Inhibitory- make the brain more calm
Imbalance of no. of neurotransmitters- associated with atypical behaviour
(Crockett et al., 2008) (Carre et al., 2006)
