Learning: glutamate, dopamine Mood basic drives: seretonin Emotional memories and has roles in attention, alertness, states of arousal; also called noradrenaline: norepinephrine. Inhibitor: Gamma-amino butyric acid (GABA) Acetylcholine-
Terms in this set (10)
a neurotransmitter believed to be involved in a wide range of psychological activity; low levels are associated with sad and anxious moods, hunger, food cravings and disruption of the sleep cycle
A substance that occurs as both a neurotransmitter and "stress hormone" ; as a stress hormone it is secreted from the adrenal medulla during times of heightened emotional arousal; as a neurotransmitter, it influences formation of emotional memories and has roles in attention, alertness, states of arousal; also called noradrenaline.
a chemical substance made by neurons that transmits messages across the synaptic gap between the axon ending of one neuron and the dendrite of another; enables communication between neurons
Long-term potentiation (LTP)
the long-lasting strengthening of the synaptic connections of neurons, resulting in the enhanced or more effective functioning of the neurons whenever activated
the main excitatory neurotransmitter for information transmission throughout the brain; plays crucial roles in the growth and strengthening of synaptic connections during learning and memory formation.
Gamma-amino butyric acid (GABA)
the primary inhibitory neurotransmitter in the central nervous system that works throughout the brain to inhibit the activity of postsynaptic neurons.
a neurotransmitter believed to be involved in learning (including reward-based learning), memory, schizophrenia, pleasure, motivation, emotional arousal and the control of voluntary movements.
an explanation of the cause of the positive symptoms of schizophrenia in terms of excessive activity of the neurotransmitter dopamine in the brain.
Dopamine reward system
a neural pathway in the brain that, when stimulated, provides "pleasurable experiences."
a neurotransmitter involved in learning, memory, attention, sleeping, dreaming and motor control; found to be at abnormally low level in the brains of people suffering from Alzheimer's ; drugs that inhibit its activity cause temporary memory loss.
