- Front
- Back
|
Localisation |
specific areas of brain are responsible for particular physical and psychological function |
|
|
Motor area |
back of frontal lobe- voluntary movement by sending signals to body, right hem=left vice versa (contralateral) |
|
|
Visual area |
back of occipital- receives+processes visual info- damage to one side can produce blindness to other side of visual field |
|
|
Somatosensory area |
front of parietal- receives sensory info from skin ->produce sensations related to pressure, temp and pain |
|
|
Auditory area |
temporal lobe- analyse+process acoustic info |
|
|
Broca’s area |
left frontal- involved in speech production-> broca’s aphasia-unable to produce speech (slow, lacks fluency) |
|
|
Wernicke’s area |
left temporal- speech comprehension; wernicke’s aphasia- inability to comprehend speech |
|
|
AO3- support from case study patients |
TAN- only say tan; left frontal lobe=damaged- apart from speech production, he seemed to function normally- suggest broca’s area damaged+responsible for speech production |
|
|
AO3- plasticity research suggests brain can work holistically |
lost/compromised functions can be recovered- axon sprouting, recruitment of homologous sites. Lashley- law of equipotentiality- surviving brain circuits aid some neuro action-cast doubt on brain being solely lateralised |
|
|
AO3- brain scan evidence |
Peterson et al- wernickes area active for listening task and broca’s during reading task
Tulving et al- semantic and episodic memories reside different sides of prefrontal cortex->many brain func=localised |
