Q

function of the occipital lobe?

A

visual processing and information from the eyes

17
Q

what is localisation of language?

A

specific areas of the brain link to processing of language

18
Q

what is the third biological assumption?

A

neurotransmitters?

19
Q

what are neurons?

A

electrically excitable cells that form the basis of the nervous system with dendrites on the ends to connect to many other neurons

20
Q

how do neurons work?

A

neurons connect at a synapse where the messages are relayed by neurotransmitters which will stimulate or inhibit receptors in another neuron

21
Q

what is the role of neurotransmitters in mental health?

A

serotonin - too little found in those suffering from depression but can be increased by antidepressants
dopamine - high levels associated with SZ symptoms
