Flashcards in Chapter 17 (continued) Deck (15):
1

A disorder characterized by uninhibited responses, lack of sustained attention, and hyperactivity.
Most common behavior disorder in childhood

ADHD

2

a psychological reaction caused by the perception of aversive or threatening stimuli

stress response

3

a general, imprecise term that can refer either to a stress response or to a situation that elicits a stress response

stress

4

physiological reactions that prepare us for the strenuous efforts of fighting or fleeing

fight or flight response

5

Hormone of the adrenal cortex that are important in protein and carbohydrate metabolism, secreted especially in times of stress.

glucocorticoid

6

a hypothalamic hormone that stimulates the anteriour pituitary gland to secrete ACTH

CRH

7

a hormone released by the anteriour pituitary gland in response to CRH; stimulates the adrenal cortex to produce glucocorticoids

ACTH

8

a psychological caused by exposure to a situation of extreme danger and stress; symptoms include recurrent dreams or recollections; can interfere with social activities and cause a feeling of hopelessness

PTSD

9

the pairing of the context/cue to the aversive stimuli

aquisition

10

similiar to consolidation
- protein synthesis dependent
- second time window where you can interrupt a memory (memory = maluable)

reconsolidation

11

- protein synthesis dependent
- laying down of a memory

consolidation

12

serine/threonine protein kinase that regulates cell growth, cell mobility and protein synthesis

mTOR

13

release of stress hormones

PVN secretes CRH
CRH activates anteriour pituitary secrete ATCH
ACTH atimulates adrenal cortex
Adrenal cortex releases cortisol (GLUC)

14

animal models for anxiety

predator odor (emotional stress)
isolation stress (chronic - singly housed)
chroic unpredictable stress (submitted to stressor once a day for several days)
submersion stress
fear conditioning (most common - associate with shock, put in same context - no shock)
social defeat

15

mTOR/reconsolidation/PTSD

give animal mTOR - reduction in memory
- blocking on reconsolidation
PTSD - give protein inhibitor (b/c reconsolidation is protein synthesis dependent) to interupt memory
can then try to delete fear component of memory.
