Somatosensory cortex
Parietal lobe
Auditory cortex
Temporal lobe
Visual cortex
Occipital lobe
Motor cortex
Frontal lobe
Where is the motor area located
In the frontal lobe, if the the left area is damaged other right side will be impaired, can lead to paralysis. Responsible for voluntary movements
Where is the somatosensory area located
In the parietal lobe, it receives incoming information from the skin to produce sensations like pain, pressure and temperature
Where is the visual area located
In the occipital lobe, receives and processes visual information, info from your left visual field is processed in the right and vise versa
Where is the auditory area located
In the temporal lobe, responsible for analysing and processing acoustic information
Where is the language area- Broca’s area located
Left frontal lobe, brocas aphasia is where people have slow and inarticulate speech but they can understand language spoke to them
Where is Wernickes area located
Back of temporal lobe, wernickes aphasia is where people can speak perfectly well but are unable to understand what they themselves had said or language that someone else had spoken to them
What change occurred in Phineas Gage after his accident?
His personality changed due to damage to the left frontal lobe
This change may not be representative of all individuals with similar brain injuries.
What does the localization of function in the brain refer to?
The idea that specific functions are mapped to specific areas of the brain
This concept is supported by various studies, including those on language and memory.
Which areas of the brain are active during language tasks according to Petersen et al. (1988)?
- Wernicke’s area during listening tasks
- Broca’s area during reading tasks
This demonstrates that these areas are involved in speech comprehension and production.
What did Tulving et al. (1994) discover about memory storage?
Episodic and semantic memories are stored in different parts of the pre-frontal cortex
This provides scientific evidence for the localization of different memory functions.
Who criticized the localization of brain functions and when?
Lashley in 1950 and Dronkers in 2007
They argued that higher cognitive functions are not confined to specific brain areas.
What was Lashley’s conclusion from his experiments with rats?
Learning is not localized to specific areas but requires the whole brain
He named this concept the equipotentiality theory.
What does the equipotentiality theory suggest?
Basic motor and sensory functions are localized, but higher mental functions are not
This theory emphasizes a more holistic approach to brain function.
What did Dronkers et al. (2007) find in their MRI scan of Tan’s brain?
A lesion in Broca’s area, but evidence of other contributing areas to speech production
This suggests that Broca’s area may not be the only region responsible for speech production.
