☆ Theoretical Approaches (20) ― Biological and Neurological Bases Flashcards
Theoretical Approaches in Explaining the Etiology of Psychological Disorders (20)
study of the nervous system, especially the brain to understand behavior, emotions, and cognitive processes
Neuroscience
chemical messengers of the body
Neurotransmitter
effectively increase the activity of the neurotransmitters
Agonist
(Excitatory)
decrease or block neurotransmitter
Antagonist
(Inhibitory)
produces effects opposite to those produced by the neurotransmitters
Inverse Agonists
neurotransmitter is released, quickly broken down and brought back to the synaptic cleft
Reuptake
Neurotransmitter
most abundant in the brain and plays a key role in thinking, learning, and memory
Glutamate
(E) [ memory ]
High Glutamate causes
- Psychosis
- Neuron Death
Low Glutamate causes
Huntington’s Disease
Neurotransmitter
most common inhibitory neurotransmitter in the brain and regulates mood, irritability, sleep, seizures
GABA
Gamma-Aminobutyric Acid
(I) [ calming ]
High GABA causes
Relaxation
Low GABA causes
Anxiety/OCD
Neurotransmitter
regulates mood, sleep patterns, sexuality, appetite, and pain
Serotonin
(I) [ mood ]
High Serotonin causes
Mania
Low Serotonin causes
- Depression
- Anxiety
- Eating Disorders
Neurotransmitter
body reward system, pleasures, achieving heightened arousal and learning
Dopamine
[ pleasure ]
Low Dopamine causes
Parkinson’s Disease
High Dopamine causes
Schizophrenia
Neurotransmitter
responsible for fight-or-flight response
Epinephrine
[ fight-or-flight ]
High Epinephrine causes
- Stress
- Sleep Disorders
Low Epinephrine causes
- Fatigue
Neurotransmitter
alertness, arousal, decision-making, attention, and focus
Norepinephrine
[ concentration ]
High Norepinephrine causes
Mania
Norepinephrine causes
Depression
