What is the Brain hypothesis?
|
brain gives rise to the mind
|
|
|
What is the Babinski sign?
|
Babinski sign: touch newborn babies foot and toes spread → sign of neurological health (connection to spinal cord is good). After 8 months this doesn’t occur b/c brain is controlling it, and toes will come together
|
|
|
What is the snouting reflex?
|
Snouting reflex: touch babies upper lip → they suck. After 6 months it will go away. If someone does this they have frontal lobe damage.
|
|
|
What does dualism mean?
|
Dualism: brain and mind are so materially different that they cannot be the same thing. Brain and mind are two separate thing.
|
|
|
What does Materialism claim?
|
The brain is the material of the mind → brain hypothesis
|
|
|
What is Phrenology?
|
belief that when one area of the brain is stronger it will get bigger (ex. Better mother = bigger maternity area of the brain and you can feel a bump on the head)
|
|
|
What is Cognitive neuropsychology?
|
trying to study the brain using those that have sustained brain injury
|
|
|
Where is Broca's area?
|
Left inferior frontal lobe
|
|
|
Where is Wernicke's area?
|
Left superior frontal lobe
|
|
|
What happens in Broca's aphasia?
|
Inability to speak fluently
|
|
|
What happens in Wernicke's aphasia?
|
Impaired comprehension, fluent speak
|
|
|
Which brain part of Patient H.M. was removed?
|
Bilateral medial temporal lobe -> hippocampus
|
|
|
Where is hippocampus located?
|
medial temporal lobe
|
|
|
What does stimulation of frontal lobe do?
|
twitch, motor/premotor → movements
|
|
|
What does stimulation of parietal lobe do?
|
Somatosensory/visual hallucinations
|
|
|
What does stimulation of occipital lobe do?
|
visual hallucinations
|
|
|
What does stimulation of temporal lobe do?
|
Visual/auditory hallucinations, activate whole memories
|
|
|
What does stimulation of prefrontal lobe do?
|
Nothing
→ ‘silent cortex’
• People inferred this part wasn't important |
|
|
Where was Phineas Gage's injury located?
|
total ablation of orbitofrontal cortex
|
|
|
What does a PET scanner scan?
|
PET scanner (1970’s) → look at brain chemistry and blood flow
o Neurochemicals o Blood flow and neural activity |
|
|
What does an MRI scanner scan?
|
MRI scanner (1970’s-80’s)
o Structure and [later] function and blood flow |
|
|
What is Transcranial magnetic stimulation for?
|
"Virtual lesions" → disrupt brain areas as if they were damaged
|
