| Term | Definition |
|---|---|
| dopamine | the neurotransmitter that stimulates the body’s natural “feel good” reward pathways, producing pleasant euphoric sensation under certain conditions. |
| motor functions | Associations in both learning and programming behavior or activities that are repetitive and done become automatic |
| Basal ganglia | Subdivisions: putamen, globus pallidus, and caudate |
| Receptors | exhibit receptor sensitivity indicating that they have the capacity to change. |
| neuron | A nerve impulse originates in the ____________ and is carried across the synaptic cleft during transmission |
| Molecular genetics | genetic contribution to development of psychiatric disorders |
| Population genetics | – Family studies – Twin studies – Adoption studies |
| Excitatory neurotransmitters | Acetylcholine Dopamine Serotonin |
| Inhibitory neurotransmitter | Gamma-aminobutyric acid (GABA) |
| Substance P and somatostatin | (pain transmission and endocrine functioning) |
| Non-opioid neuropeptides | Substance P and somatostatin (pain transmission and endocrine functioning) |
| Opioid neuropeptides | Endorphins, enkephalins, and dynorphins |
| Endorphins, enkephalins, and dynorphins | (endocrine functioning and pain suppression) |
| Types of neurotransmitters | Cholinergic Biogenic amines Amino acids Neuropeptides |
| frontal lobe | ____________ controls motor speech function, personality, and working memory—often called the executive functions that govern one’s ability to plan and initiate action; |
| parietal lobe | controls the sensory functions; somatosensory |
| temporal lobe | contains the primary auditory and olfactory areas; expressions, Wernicke’s area |
| occipital lobe | controls visual integration of information, visual perception, recognition |
