What are the two main forms of therapy associated with hemineglect?
Give this one a try later!
1. Visual scanning training - reminds client to look leftward
2. Right shifting optical prisms - over time this compensates for errors.
,What did Levay find in regards to sexual orientation, and what were the two primate
studies referencing this?
Give this one a try later!
1. Found that that anterior hypothalamus was involved in male-typical
sexual behaviour (many critiques)
2. Allen found sex-difference size in INAH2 and INAH 3 genes (and
Homosexual smaller than heterosexual, similar to woman) - size correlated
with sex of attraction
3. Slimp found lesioning the above led to monkeys to change sexual
orientaion
What are some of the pharmacological and functional evidence for schizophrenia
Give this one a try later!
1. Best medications bind to D2 dopamine receptors (but may cause
parkinsons symptoms) - more dopamine receptors in a schizophrenic brain.
Most narcoleptic are dopamine antagonists.
2. Frontal lobe is more hypofrontal (less glutamanergic reaction, so less
dopamine released to nucleus accumbus) - and increased basal ganglia
activity.
What are Pinel's definitions of learning and memory?
Give this one a try later!
, Learning = how experience changes the brain
Memory = How these changes are stored and retrieved
What are the ethical dilemmas raised by the Owen (2006) study?
Give this one a try later!
1. There's misunderstandings of MRI use; families may use this as evidence
to claim that their loved one is aware.
2. Claiming consciousness may be hard for families; could provide false
hope, or cause burden, or grief.
3. Could guide clinical management; and intensify or remove rehab.
4. Could it be used to guide euthanasia?
What is a 'minimally conscious state', what is locked-in syndrome, and what is the
MAJOR studies to do with this?
Give this one a try later!
1. Much like UWS, but may show signs of awareness (like reaching out)
2. Person is fully conscious but can't move (except maybe eyes) - can
communicate with this
3. Owen et al (2006) - Patient told to imagine either playing tennis or
standing in her house. These answers lit up certain parts of the brain on MRI
scans, and allowed patients to answer yes/no questions - perhaps
representing a clear act of intention. Also asked "are you in pain?".
, What is the possible neurological basis for psychological disorders?
Give this one a try later!
Failure to form appropriate connections or prune may lead to
Schizophrenia or Aspergers respectively.
What would a hemineglect patient do in regards to reading, drawing a clockface,
copying a drawing, and bisecting a line?
Give this one a try later!
1. Most will miss the left side of each line; or even the left of each word.
2. Will pack all the numbers on the right side of the clockface.
3. Will not draw the left side, or the left side of objects.
4. Bisect will be centred to the right.
Why do lights of equal (higher) intensity but differ in wavelength differ in both hue
and brightness?
