Localisation Flashcards
1
Q
What is it
A
Refers to the principle that specific functions have specific locations in the brain
2
Q
Motor Cortex
A
- Responsible for voluntary motor movements
- Located in the frontal lobe along the precentral gyrus
- Each hemisphere operates the opposite side of the body
3
Q
Somatosensory cortex
A
- Detects sensory events arising from the brain
- Located in the parietal lobe along the precentral gyrus
4
Q
Brocas area
A
- Tan could understand everything but not respond with understandable language
- Deficit in left frontal hemisphere
- Language and the other involved in responding to cognitive tasks
5
Q
Werknickes area
A
- Found an area in brain for understanding language
- Posterior portion of the left temporal lobe
- Could speak but not understand
- Neural loop - running between two areas
6
Q
Visual centres
A
- Located in the visual cortex in the occipital lobe
- It begins in the retina where the light strikes the photoreceptors.
- Nerve impulses are transferred from the retina to the brain via the optic nerve. Terminate in the thalamus
7
Q
Auditory centres
A
- Lies in the temporal lobe
- Pathway begins in the cochlea
- Sound waves are connected to nerve impulses which travel via the auditory nerve to the auditory cortex
- The brain stem is the first stop, then the thalamus, then the auditory cortex
8
Q
A03: Equipotentiality
A
Lashley believed that basic motor and sensory functions were localised but complex functions weren’t. He claimed the effects of brain damage were due to the nature of the damage rather than the localisation
9
Q
A03: Communication
A
Complex behaviours are built up gradually
10
Q
A03: Aphasia studies
A
Improved ability to produce language (expressive). Impaired ability to understand language (receptive).
11
Q
A03: Individual differences
A
Can’t use case studies
