Psych Test #3
Term | Definition |
---|---|
Descriptives | non-experimental methods; can only state what is happening |
Dendrites | receives info from other neurons |
Soma | processes info given by dendrites |
Motor Neurons | movement; sends signals from NS to rest of body |
Neural Pathway | more you use the pathway, the stronger/easier it becomes when used (neurons communicate w/ each other towards outcome |
Chemical Signal | sends signals using neurotransmitters; talks to neurons by releasing chemicals |
Electrical Signal | electrical impulse; message travels along Axon to AT (neural activation) occurs in one neuron |
Types of Neurons | Motor Sensory Interneurons |
Neurons | cell specific to NS; sends & receives information |
Two Divisions of NS | Central NS Peripheral NS |
Neurogenesis | neural creations; new neurons grow & develop when new things are experienced |
Neuroplasticity | flexibility of neurons or ability to adapt |
Neuroscience | science of NS (brain, spine, nerves) electrical and chemical signals |
Correlation | association of 2 variables; strongly related or no/low relation (NOT CAUSAL, PREDICTION) |
Negative Correlation | (-), 2 variables move in opposite direction; NO CONTROL/INFLUENCE |
Positive Correlation | (+), 2 variables move in same direction; cannot say one thing causes another |
Myelin Sheath | protects axon; speeds up transmission |
Axon | transmits message |
2 Functions of Neurons | chemical and electrical |
Interneurons | connectors/creates links among neurons; brain & spine |
Axon Terminal | end of neuron; allow for connectors w/ other neurons |
Somatic NS (PNS) | voluntary movements |
Automatic NS | involuntary movements |
Transduction | sensory neurons take info and converts to electrical and chemical signals |
Central NS | brain-interpret, connect, make decisions (heavy lifter) spine-basic decisions, reflex (automatic beh.) |
Sensory Neuron | eyes, ears, nose, mouth, skin; pick up physical stimuli/info |
Correlation Designs | what is happening between 2 variables |
