Psychology 40 lifespan

/in /by

Norman has noticed some changes in his wife, Peg, over the past 6 or 8 months. She seems more forgetful

and moody and got lost driving to church twice in one month. Peg no longer wants to visit with friends and

family and is unable to explain changes in her behavior. She is prone to crying spells, and although he

tries, Norman doesn’t seem to be able to comfort his wife. Norman has decided to take Peg to their family

physician to find out if her symptoms have a medical explanation.

Answer the following questions in this Db:
How should the physician go about determining if Peg has Alzheimer’s disease, cerebrovascular dementia,

subcortical dementia, or depression? That is, what techniques are used to diagnose each of the

disorders?
If Peg has Alzheimer’s, how will her physician rule out cerebrovascular dementia and depression?
Finally, create a list of recommendations that will help Norman care for Peg if her diagnosis is Alzheimer’s

disease

The Cross-Pollination of Music in the 1960s

/in /by

There was a great deal of ‘hybridization’ going on in the music of the 1960s. Whether it was the influence

of Muddy Waters’ Electric Blues on the Rolling Stones, or Woody Guthrie’s nasal, ‘champion of the people’

influence on Bob Dylan, or Dylan’s influence on the next generation of folk-rock bands like the Byrds, or

Leadbelly’s influence on Lonnie Donegan, or Donegan’s influence on the Beatles…the times they were a-

changing…and so was the music.

For this chapter’s discussion, I want you to pick one band/artist who directly influenced another

band/artist (like the ones I’ve just mentioned) and tell me about that influence. You must also attach a video

of a song that represents this influence. It doesn’t necessarily need to be a cover (though it can be).

Cost-benefit analysis that addresses Wisconsin’s ”Safer at Home” policies

/in /by

The project deliverable will be a dispassionately written analytical paper that (1) explains the observed or

expected impact of the ”Safer at Home” policies, (2) discusses potential confounders that might threaten

the validity of the analysis, (3) identifies actions that could be undertaken to mitigate those confounders,

and (4) advocates for a particular course of action based upon the [expected] net benefit of the policies.

The paper should be written for an audience assumed to be neutral or uninformed.

Generation of an Action Potential

/in /by

1- Where is the action potential initially generated?
2- What happens to voltage-gated sodium channels at threshold?
3- What happens if there is a weak stimulus at the initial segment, and threshold is not reached?

4- What are the names of the two gates on the voltage-gated sodium channels?
5- Just after the peak of the depolarization phase, what happens to the activation and inactivation gates of

voltage-gated sodium channels?

6- What happens to the membrane potential during the repolarization phase of the action potential, and

what causes this change?
7- At the end of the action potential’s depolarization phase, the membrane potential is about __

mV.
8- The depolarization phase of the action potential is primarily due to a change in membrane permeability

to _.
9- If the membrane reaches the trigger point, known as threshold, it will generate a(n) _.
