Lecture 1 - Brain Flashcards
which side of the brain is the dominant side and what hand does it control + what’s its main function?
left
right hand
language
what are all the lobes/cortexes of the brain? + two structures that are not within a lobe
frontal, parietal, temporal, occipital
+ cerebellum + brainstem/spinal chord
premotor cortex lobe location and function
- temporal love
-planning motor activity
pre central gyrus:
another name for it, lobe location and function
primary motor cortex
frontal lobe
signals for movement/carries out motor activities
post central gyrus:
another name for it, lobe location and function
primary sensory cortex
parietal lobe
recieves sensory information
Parietal Association Cortex function
spatial skills, 3D recognition (shapes, faces, concepts, abstract perception)
supramarginal gyrus:
lobe location and function
parietal lobe
reading, muscle control, interpretation
angular gyrus:
lobe location and function
parietal lobe
writing, precise motor/muscular activity
primary visual cortex:
lobe location and function
occipital lobe
receives input from eyes, interprets periphery into colour and shapes
secondary visual cortex:
lobe location and function
occipital lobe, takes visuals in, interprets into context of past experiences
primary auditory cortex:
lobe location and function
temporal lobe
organises a system of sounds: tones and times
language + sound
wernicke’s area: another name for it,
lobe location and function
secondary corticol area
temporal lobe
interpret of language (not sound that’s not language)
lateral sylvian fissure role
separates temporal lobe from frontal/parietal lobes
arcuate fasculus: matter description,
lobe location and function
made up of white matter
connects frontal, parietal and temporal lobes
(joins broca’s and wernicke’s areas + connects understanding and speaking)
frontal association cortex:
lobe location
MC.PIB
intelligence, personality, behaviour, mood, cognitive function
temporal association cortex:
lobe location and function
MAMI - acronym
- memory, mood, aggression, intelligence
broca’s area:
lobe location and function
frontal lobe
speech production/articulating spoken word
non-dominant hemisphere (right) function
NESCA
- non-verbal/body language
- emotional expression (tone of language)
- spatial skills (3D)
- conceptual understanding (object recognition)
- artistic/musical skills
grey matter
- make up
- function
lots of neuron’s cell bodies
information processing (think, reason, perception, sensation, voluntary movement, learning, speech, cognition)
white matter function
provides communication between different grey matter areas + between grey matter areas and the rest of the body
wernicke’s area aphasia clinical description
- lesion/challenge/tumor/stroke
- inability to understand spoken word
- if person can speak fluently, what they say doesn’t relate to what was asked
broca’s aphasia clinical description
- non-fluent/motor aphasia
- difficulty in expressing spoken word/what they want to say
connection aphasia clinical description
speaking and understanding unaffected but not connected
cingulate gyrus:
lobe location and function
frontal lobe
gets right type of information to the right part of the brain
ventricles:
lobe location and function
frontal, occipital, temporal
fluid filled space that goes from middle of the brain down to central structures of the brain
hypothalamus function
hormone regulation of the brain
what 3 structures make up the hindbrain
cerebellum + pons + medulla
Exner’s area function
writing and reading
Homunculus defintion
a representation of the human body in the brain
cerebellum function and another name
primary auditory cortex
organises sounds (tones/time)
