Q

James-Lange predictions

A

Those with weak physical response should feel less emotion, increasing one’s autonomic or motor response should enhance emotion

Q

How can we increase emotion, according to James-Lange

17
Q

Attack behaviours

A

Corticomedial area of amygdala. First attack response increases likelihood of another

18
Q

Agressive behaviours - environmental factors

A

exposure to lead, witness/victim of violence in childhood, violent neighborhood

19
Q

Twin studies in aggressive behaviours

A

monozygotic > dizygotic

20
Q

Low MAOa + childhood maltreatment

A

high antisocial behaviour

21
Q

High MAOa + childhood maltreatment

A

lower antisocial behaviour

22
Q

High testosterone

A

higher rates of violent behaviour

23
Q

Triple imbalance hypothesis

A

Cortisol, serotonin, testosterone. High rates of violence when cortisol is low and testosterone is high. Serotonin inhibits violent impulses.

24
Q

Testosterone might inhibit the ability to recognize angry behaviour - true/false

A

true. May increase response of amygdala, and decrease ability of cerebral cortex to identify and regulate.

25
Q

Turnover

A

the amount of neurotransmitter that is released and resynthesized by neurons

26
Q

low serotonin turnover =

A

high aggressive behaviour

27
Q

low levels of 5-HIAA indicate

A

low serotonin levels

28
Q

serotonin levels are influenced by

A

diet, genetics, tryptophan hydroxylase

29
Q

Amygdala is crucial in

A

regulating fear

30
Q

The startle reflex is

A

very fast, mediated by medulla and pons, unlearned

31
Q

fear signals enhance startle, pleasant decrease - true/false

A

true

32
Q

Amygdala to hypothalamus

A

automatic reaction

33
Q

Amygdala to prefrontal cortex

A

approach/avoid

34
Q

Amygdala damage results in

A

startle response not enhanced by fear inducing stimuli

35
Q

Damage to amydala does not remove all emotion - true/false

A

true

36
Q

Urbache-Wiethe disease

A

buildup of calcium in the amygdala - results in fearlessness and difficulty processing emotion on faces

37
Q

fMRI of amygdala shows

A

activity is strongest when processing ambiguous emotional facial expressions

38
Q

Bed nuclius of the stria terminalis

A

regulates long term, generalized emotional arousal

39
Q

Panic disorder

A

women > men, possible genetic component (15% joint laxity), abnormalities in the hypothalamus, decreased GABA increased orexin

40
Q

Drugs intended to control anxiety

A

alter activity at amygdala synapses. Excitatory NT CCK and orexin, inhib NT GABA.

41
Q

Anxiolytic drugs

A

target GABA

42
Q

Benzodiazepines are most commonly used anxiolytic drugs

A

bind to GABA
