Parasympathetic
Unconscious and does is rest and digest
Sympathetic

Serotonin, dopamine, endorphins, noradrenaline
Broca’s area
-Left frontal lobe
-directs primary motor cortex
-linked to speech, sentence structure and grammar
-deficit= language production/speech becomes jumbled
Primary sensory cortex
Parietal lobe
Primary visual cortex
Occipital lobe
Wernicke’s area
-Left temporal lobe
-connected to Broca’s area via nerve fibres
-response for comprehension of sound
-deficit=lack of meaning in speech/comprehension of speech
Name the types of psychoactive drugs
Depressants, stimulant, hallucinogen
