PSYCH TEST
| Term | Definition |
|---|---|
| Thalamus- | sensory information except for smell |
| Amygdala- | associating emotions with experiences - fight or flight |
| Hippocampus- | formation of new memories (going to sombr) |
| Hypothalamus- | regulation of body functions (sleep/temp) and motivation (hungry/thirst/sexy time) |
| Prefrontal Cortex - | attention, self-control, social processes (interactions) |
| (Facial Recognition--really part of visual) - | Fusiform Face Area |
| Cerebral Cortex - | thoughts, planning |
| Primary Auditory Cortex - | hearing, volume/direction of a sound |
| Primary Visual Cortex - | vision, orientation, size, and color |
| Primary Somatosensory Cortex- | touch, right side of the body |
| Primary Motor Cortex- | motor functions, left side of the body |
| Endorphins- | Pain reduction and reward/runner’s high |
| Acetylcholine- | motor controls over muscles, attention, memory, learning, and understanding when to sleep and rest your body. |
| Glutamate - | enhanced action potentials, learning and memory |
| Serotonin- | emotional states/impulse control - dreaming/relaxation |
| Dopamine - | reward/motivation/motor control over voluntary movements |
| Lack of Dopamine - c | an lead to Parkinson’s disease |
| Norepinephrine- | Alertness and reaction time, helps you understand what's going on in chaotic situations |
| Lack of Serotonin - | leads to anxiety, food cravings, aggressive behavior, When neurotransmitters miss the synapse, it will cause clinical depression |
| Excessive GABA - | overexcitement in the brain, can destroy the neurons |
| Lack of GABA - | can lead to epileptic seizures |
| GABA - | anxiety reduction |
| Dendrites- | short, branch-like extensions of the cell body, receive signals from the neuron’s cell body |
| cell body - | collects the information from neurons, electrical currents transmit to the axon |
| Axon- | long narrow part of the cell body that connects one neuron to another, releases to the terminal buttons |
| terminal buttons- | release chemical signals from the neuron into the synapse |
| Synapse- | space where the neurons communicates through neurotransmitters - like a cliff |
| Neurons- | individual cell in the nervous system |
| Neurotransmitters- chemical substances that carry one neuron to another, cycle is like a highway | chemical substances that carry one neuron to another, cycle is like a highway |
| myelin sheath- | protects the axon |
| Peripheral nervous system- | skin, muscles, jaw |
| Nervous system - | brain and spinal cord |
| 6 lobes of the brain | frontal lobe, parietal lobe, cerebellum, brain stem, temporal lobe, occipital lobe |
