Biological Assumptions

Question 1

Neurotransmitters

Answer 1

Chemical messengers that relay messages at the synapse

Play role in mental health:

Serotonin = Mood, Sleep, Depression
Dopamine = Schizophrenia,

Question 2

Localisation of brain function

Answer 2

Areas of brain responsible for different things

Cerebral cortex = 4 lobes:

Frontal = Personality, Broca’s area (Produce lang)

Parietal = Receive sensory info

Temporal = Wernickes area (Understanding lang)

Occipital = Visual processing

Broca’s + Wernicke’s = Localisation of lang

Question 3

Evolutionary influences

Answer 3

Evolution means human brains have adapted to needs of individual environments

(Explain natural selection)

EEA = Environment of evolutionary adaptedness

(Environment to which species are adapted to due to selective pressures at time)

E.g. Human brain large due to complex social organisation of species
