Question | Answer |
What happens if the Corpus Callosum is severed? Give one example | Person appears normal and deficits are noticed when they are tested under experimental conditions. Objects presented to left cannot be named as image goes to right hemisphere. |
What is the Corpus Callosum | A band of fibers connecting the left and right hemisphere of the human brain |
Why is the corpus callosum sometimes severed? | It is severed in cases of severe epilepsy that cannot be controlled by medication. |
Why is the brain convoluted in appearance? | If tissue of cerebral cortex laid out flat would take about 2-3 square metres. Brain tissue is folded in on itself in a series of convolutions to enable brain to fit inside small space of skull. |
Convolutions in the brain give us? | greater cognitive power as humans. |
How many lobes in the brain? | 4 |
Parietal lobe disorders (Damage to sensory cortex) results in deficits of.. | Perception and cognition not simple sensory disturbances. |
Damage to sensory cortex can lead to problems with (3) | Spatial locations for objects memory for location map reading |
Hemineglect | Person cannot attend to stimuli presented to side of space opposite the brain lesion |
Left hemisphere | Language tasks |
Right hemisphere | Spatial awareness |
Cerebellum | Balance and co-ordination |
Occipital lobe disorder | Motion Blind Prosopagnosia- Ability to recognize familiar faces Visual agnosia- the inability to recognise familiar objects |
Do equal areas of the body receive equal cortical space? | No. |
Temporal lobe Functions (3) | Audition Understanding Language Memory |
Temporal lobe disorders? | Wernicke's Aphasia -People cannot understand what they hear. -Speak Fluently. -Speech has no meaning. |
Frontal lobes | -Uniquely human -Not fully developed until age 25 -Speech production |
Broca's Aphasia? | Person can understand speech but cannot produce speech. Person understands something is wrong with them. |
Frontal lobe | Reasoning, planning, parts of speech, movement, emotions, problem solving |
Parietal lobe | touch pressure temperature pain texture |
Temporal lobe | Perception of auditory stimuli. Memory (hippocampus) |
Occipital lobe | Sight |
Cerebellum | Balance, co-ordination, skilled motor-activity |
