lobes of the brain (chapter 4) Flashcards
what are the 4 distinct regions of the brain?
the frontal lobe, parietal lobe, temporal lobe and the occipital lobe
what are the frontal lobe’s 4 areas
- pre-frontal cortex
- primary motor cortex
- pre motor cortex
- broca’s area
what is the pre-frontal cortex
the pre-frontal cortex is a part of the frontal lobe, and is the association area.
it is responsible for:
- planning
- reasoning
- judging
- initiative
- problem solving
- personality
- attention
- control of emotions
primary motor cortex
- initiates and controls voluntary movement of skeletal muscles
- contralateral functioning
- upside-down representation
(frontal lobe)
pre motor cortex
- voluntary motor movement
- sends sequence of movements to PMC
(frontal lobe)
broca’s area
production of articulate speech that is clear and fluent (in the left hemisphere) via the muscles that control the mouth
(frontal lobe)
what are the areas in the parietal lobe
- primary somatosensory cortex
- association area
primary somatosensory cortex
- responsible for processing sensation of touch, pressure, temperature and pain
- contralateral functioning
- upside-down representation
(parietal lobe)
association area (parietal lobe)
- location of body in space
- location of objects around them
- perception of 3D shapes and designs
what are the 2 areas in the occipital lobe
- primary visual cortex
- association area
primary visual cortex
- receives visual input from each retina
- registers and processes different visual stimuli
(occipital lobe)
association area (occipital lobe)
- organisation of visual stimuli
- interpretation, identifying objects
- interaction with other lobes to integrate visual info with memory, language and sounds
what are the areas in the temporal lobe
- primary auditory cortex
- association area
- Wernicke’s area
primary auditory cortex
registers and processes auditory info from speech, music or non-verbal sounds (pitch and loudness)
association area (temporal lobe)
- associated with hearing, understanding speech and interpreting sounds
- plays an important role in forming memories
- facial recognition performed in right temporal lobe
