41
Q

in the neuroscience paradigm, what are mental illnesses linked to?

A

abherrant processes in the brain

42
Q

three major components of the neuroscience paradigm

A

Three major components:
- Neurons and neurotransmitters
- Brain structure and function
- Neuroendocrine system

Neumonic- 3 pals holding hands, a neuron, a building that looks like a brain, and a stomach with a sign that says enzos

43
Q

Neurons

A

cells of the nervous system

44
Q

four major parts of neurons

A
  • Cell body
  • Dendrites
  • Axons
  • Terminal buttons

Neumonic: body where cell body is, dendrites as roots going to dennys, axons as axel rose, terminal buttons as buttons with airport terminal

45
Q

Nerve impulse

A
  • Dendrites or cell body stimulated

46
Q

Synapse

A

gap btwn neurons

47
Q

Neurotransmitter

A

Chemicals that allow neurons to send a signal across synapse to another neuron

Neumonic: evil lab sending chemicals

48
Q

types of effects of a neurotransmitter being absorbed

A

Excitatory
- Stimulates action impulse

Inhibitory
- Prevents action impulse

Neumonic: think of neuron absorbing chemical then either getting excited to take action, or getting shy and inhibited and stops impulse

49
Q

Reuptake

A

Reabsorption of leftover neurotransmitter by presynaptic neuron

Neumonic: think of first neuron reobsorbing leftover chemicals from synaptic gap

50
Q

some neurotransmitters that effect psychopathology

A
  • serotonin and dopamine
    • (Implicated in depression, mania, and schizophrenia)
  • norepinephrine
    • (Implicated in anxiety and other stress-related
      disorders)
  • Gamma-Aminobutyric Acid (GABA)
    • (Inhibits nerve impulses, Implicated in anxiety)

Neumonic: chemicals in a lab, one has Prozac in it, one an epipen, then yo gaba gaba

51
Q

Possible mechanisms (for how neurotransmitters contribute to psychopathology)

A
  • Excessive or inadequate levels of neurotransmitters
    (Later research found this too simple)
  • Insufficient reuptake
  • Excessive number or sensitivity of postsynaptic receptors

(Second Messengers help neurons adjust receptor sensitivity after periods of high activity)

Neumonic: think of ssris- insuffecient reuptake, and on the other neuron, the post synaptic receptors- too many and some red cause they’re too sensitive and it tickles

52
Q

Agonist drugs

A

stimulate neurotransmitter receptor sites

Neumonic: antagonist bully kids friend poking at neurotransmitter receptor sites

53
Q

Antagonist drugs

60
Q

amygdala

A

Neumonic: mandala crying with a memory thought bubble

61
Q

what does the autonomic nervous system do

A

62
Q

what are the parts of the autonomic nervous system

A
  • Sympathetic nervous system
    • Prepares body for fight or flight
  • Parasympathetic nervous system

63
Q

what is the HPA Axis of the Neuroendocrine system

A
  • involved in stress
  • HPA = hypothalamus-pituitary-adrenal cortex
64
Q

how does the HPA Axis work

A
  • Hypothalamus triggers release of corticotropin-releasing hormone (CRF)
  • Pituitary gland releases adrenocorticotropic hormone (ACTH)
  • Adrenal cortex triggers release of cortisol (stress hormone)

Takes 20-40 mins for cortisol to peak
Takes up to 1 hr for cortisol levels to return to baseline

65
Q

what effects the immune system

A

stress has effect on the immune system

66
Q

what is the body’s first line of defence (immune system)

A
  • Releases MACROPHAGES, NATURAL KILLER CELLS, and T-CELLS to destroy invaders
  • Causes INFLAMMATION or swelling
  • Stimulates release of proteins called CYTOKINES that initiate responses to infection such as fatigue, inflammation (pro-inflammatory cytokines), and activation of HPA axis

Neumonic- gangs- t-cells, natural born killer cells, macrophages

then behind them: inflammation

And behind inflammation- cyberwebkins and hpa axis

67
Q

what is the neuroscience approach to treatment

  • psychoactive drugs that alter neurotransmitter activity (e.g. antidepressants, antipsychotics, and benzodiazepines(tranquilizers))
  • also may include nonbiological interventions that can influence brain functioning
68
Q
