Q

What is wrong with patients with receptive aphasia

A

A condition where there is major impairment of language comprehension whilst speech retains natural
This is due to damage to the temporal lobe often induced by a stroke

16
Q

What does the corpus callosum do

A

It connects the right and left hemispheres allowing information to be passed between them

17
Q

What happens when the corpus callosum is severed

A

Causes patients to be able to with their left eye but not process the information and visa versa

18
Q

What does the hippocampus do

A

Memory formation and memory retrieval

19
Q

What happens when the hippocampus is damaged

A

Clive Wearing; unable to retain short term memory however still has long term memory of the past

20
Q

What does the basal ganglia do

A

Movement, balance and posture

21
Q

What is wrong with patients with Parkinson’s disease

A

They have a neurodegenerative disease caused by reduced dopaminergic function in the basal ganglia

22
Q

What is wrong with patients with Huntingdon’s chorea

A

Its a genetic disease that causes damage to the basal ganglia

23
Q

What does the thalamus do

A

Has over 40 different nuclei

Multi-model functions

24
Q

What is wrong with patients that have synasthesia

A

They have damage to the thalamus, causing ‘blending’ of information streams
This leads to feeling sounds or hearing colours

25
Q

What does the hypothalamus do

A

A collection of small nuclei e.g. temperature, hunger/thirst, neuroendocrine control, circadian rhythms and blood pressure and heart rate
Plays a major role in the flight or flight response

26
Q

What does the brainstem do

A

Controls homeostasis; Breathing, heart rate and blood pressure
Motor movements; reflexes, fine motor movements of limbs and face in conjunction with the cortex

27
Q

What is wrong with patients with ‘locked-in syndrome”

A

Damage to the pons
patient is aware but cannot move or communicate verbally due to complete paralysis of nearly all voluntary muscles in the body except for vertical eye movements and blinking

28
Q

What does the cerebellum do

A

Movement precision and coordination

29
Q

What does the spinal chord do

A

Transmits signals from/to to the brain/body

Reflexive circuits

30
Q

What is wrong with patients with plegia

A

Spinal chord injury

different levels of plegia; tetra/ quadric/paraplegia

31
Q

What does the peripheral nervous system consist of

A

Autonomic nervous system and the somatic nervous system

32
Q

What does the autonomic nervous system do

A

its for unconscious control e.g. breathing, digestion, heart rate and blood pressure

33
Q

What does the somatic nervous system do

A

Voluntary control via skeletal muscle

34
Q

What are the 4 parts of the cerebrum

A
  1. Cortex
  2. Corpus callosum
  3. Hippocampus
  4. Basal ganglia
