chapter 2 Flashcards
general aims for theories about mental disorders
- explain etiology (cause/origin) of behaviour
- identify factors that maintain behaviour
- predict course of disorder
- design effective treatments
primary proposed causes of mental disorders
- biological
- psychodynamic (freud)
- behavioural/cognitive-behavioural
- cognitive (dysfunctional thoughts/beliefs)
- socio-cultural influences
- humanistic/existential (interpersonal process)
when you only attribute the cause to one thing
reductionism
RDoC
- research domain criteria
- integrates info to understand mental illness
glial
- non neuronal cells
how many neurons does the human brain have
86 billion approx.
the ____ directs functioning of the autonomic nervous system and it controls _______
hindbrain, (digestion, breathing, and cardiovascular function)
The ______ is the centre of the reticular activating system and controls arousal levels
- midbrain (aka sleep-wake centre)
What does the forebrain control
- speech
- perception
- memory
- learning
- planning
recent theories about brain causes of psychopathology result more from _______ than to actual neural damage
neurotransmitters
neurotransmitters
- chemical substances that carry messages from one neuron to another
t or f: nerve cells in the brain are connected
false
major neurotransmitters in research
- serotonin
- dopamine
- norepinephrine
- gamma aminobutyric acid (GABA)
how can psychopathology result from neurotransmitter systems?
- too much/too little neurotransmitters released into synapses
- too many/too few receptors on dendrites
- excess/deficit in amount of transmitter-deactivating substance in synapses
- too slow/fast re uptake process
brain plasticity
- capacity of the brain to reorganize its circuitry
what are the parts that make up the peripheral nervous system
- autonomic nervous system (sympathetic and parasympathetic)
- somatic nervous system (controls muscles)
rest and digest is the ______ nervous system and fight or flight is the _______ nervous system
parasympathetic, sympathetic
HPA
- hypothalamic-pituitary-adrenal axis
- activated in response to stressors
- communication between hypothalamus, pituitary glad, and adrenal cortex
- releases cortisol into bloodstream
