Brain damage to the LEFT hemisphere to the brain either in Broca’s or Wernicke’s area

38
Q

Broca’s area

A

An area of the left frontal lobe that directs the muscle movements involved in SPEECH
Movements in motor cortex

39
Q

Wernicke’s area

A

An area on the left temporal lobe involved in language comprehension
Doesn’t understand (using some other word)

40
Q

Brain’s reorganization: plasticity

A
  • The brain’s capacity for modification as evident in brain reorganization following damage (especially in children) and in experiments on the effects of experience on brain development
  • brain’s ability to change and adapt as a result of experience
41
Q

The divided brain: corpus callosum

A

Large bundle of neural fibers that allows the 2 sides of the brain to communicate.

42
Q

What does corpus callosum do

A

Carries messages between the 2 hemispheres.

43
Q

Cutting corpus callosum leads to

46
Q

Right and left brain functions:

A 
Tendencies for each brain hemisphere to exert control over different functions
Like language (left) or perception of spatial relationships (right)
47
Q

Specialization of the cerebral hemisphere:

Left hemisphere

A

Spontaneous speaking and writing,response to complex commands, word recognition, feelings of anxiety, positive emotion

48
Q

50
Q

Prefrontal cortex

A

Judgement, planning, processing new memories

51
Q

Spinal chord

A

Allows signals to be exchanged between the brain and the sensory systems of PNS
