Localisation of Function Flashcards
Frontol Lobe
Impule inhibition + movement
Frontol lobe contains
Motor cortex and Broca’s area
Motor Cotex
Controlls voluntary movement
Broca’s area
Language production
Paritetal lobe
Sensation and perception
Parietal lobe contains
Somatosensory cortex
Somatosensory cortex
Responds to sensory info
Occipital lobe
Vision
Occipital lobe contains
Visual cortex
Visual cortex
Vision
LVF -> RVA
Cerebellum
Automates movement and balance
Temperal lobe
Auditory ability, memory acquisition, and language
Temporal lobe contains
Auditory cortex and Wernicke’s area
Auditory cortex
Analysis of speech based info
Wernicke’s area
Language comprehension
Limbic system
Emotional regulation and memory consolidation. Contains hippocampus and amygdala
Brain’s 3 concetric layers
Centric core
limbic system
cerebrum
Centric Core
Contains hypothalamus and controls basic function and endocrine system to maintain homeostasis
Cerebrum
Higher level processes
- outer most layer = cerebral cortex (grey matter)
- each sensory system sends messages to and from cerebral cortex
Hemispheres
each respobsible for specific functions though some are bilateral
Lateralisation
Dominance of one hemisphere for particular function
How are hemispheres connected?
By bundle of fibres called corpus callosum
AO3 + Neurosurgery
Treat mental disorders
DOUGHERTY ET AL = 44 pt with OCD had cingulotomy
- 30% successful response
- 14% partial
- success suggests symptoms are localised
AO3 + brains scan evidence
TULVING ET AL
semantic + episodic memory are located in different parts of PFC
- areas have different functions
AO3 + case study
PHINEAS GAGE
1m long iron pole through frontal lobe
- post mortem
- personality changed to boisterous, blasphemous, and rude
AO3 - Higher cognitive functions
LASHLEY
- removed rats cortical regions when learning maze routes
- learning required all of cortex not a particular region
AO3 - Plasticity and functional recovery
humans are able to regain cognitive abilities after damage
