Specialisations of the Brain Flashcards
What is the Cerebral Cortex imporant for?
(Outer layer grey matter)
Sensation, movement, personality etc.
What is the Hipppocampus important for?
Short to long term memory
What is the Hypothalamus important for?
Regulation of autonomic & endocrine
What is the Cerebellum important for?
Balance
Coordination
What is the Thalamus important for?
Relay station for afferent pathways to higher brain centres
What is the Brainstem important for?
Organ functions
Homeostasis
What is the Corpus callosum important for?
Axon tracts that LINK THE 2 HEMISPHERES
What is the Basal ganglia important for?
Slow sustained movement
Posture
Supress tremors
What is the Frontal lobe responsible for?
VOLUNTARY MOVEMENT
-motor control
What is the Parietal lobe responsible for?
SOMATOSENSORY PERCEPTION
-touch, heat, cold etc.
What is the Occiptial lobe responsible for?
VISION
-retinotopic map
What is the Temporal lobe responsible for?
AUDITORY FUCNTION
-tonotopic map
–also orientation of head
What is the Prefrontal cortex responsible for?
Cognition
Planning
Complex associations
Language production
Personality
What is the Parietal-Occipital-Temporal cortex responsible for?
Integrating sensory info.
Language comprehension
What is the Limbic cortex responsible for?
Memory
Emotion
Motivation
What are the 2 cortical association areas?
Broca’s area
Wernicke’s area
What is Broca’s area responsible for?
Where is it located?
Involved in SPEECH FORMATION
-Located in LEFT FRONTAL LOBE
What is Wernicke’s area responsible for?
Where is it located?
Involved in SPEECH COMPREHENSION
-Located in LEFT PARIETAL-OCCIPITAL-TEMPORAL ASSOCIATION CORTEX
What happens if the Parietal lobe association areas are damaged?
Damage to RIGHT side can cause LOSS OF AWARENESS on LEFT half body
(Neglect syndrome)
Damage to LEFT side = inability to perceive objects & APHASIA
What happens if the Limbic (temporal lobe) association area are damaged?
Damage can alter ADDICTION
(illustrating its role in providing input into the REWARD CIRCUIT in the midbrain)
