- also sometimes referred to as a retrieval practice effect or test enhanced learning
SQ3R
- survey
- question
- read
- retrieve
- review
bio psych
- scientific study of the links b/t biological and psych processes
- concerned with the links b/t bio and behavior
what are neurons
- building blocks, or nerve cells
- variate on same theme, but differ
- composed of a cell body and its branching fibers
cell body of a neuron
- nucleus with chromosomes
dendrites
- neuron’s bushy, branching extensions that receive messages and conduct impulses toward the cell body—fingers
axon
- neuron extension that passes messages through its branches to other neurons or to muscles or to glands —arm
myelin sheath
- fatty tissue layer segmentally encasing the axons of some neurons, enables vastly greater transmission speed as neural impulses hop from one node to the next
- composed of glial cells
- helps efficient transmission of signals to other cells
glial cells
- cells in the nervous system that support, nourish, and protect neurons
- may also play a role in learning, thinking, memory, “glue”, proportion of glial to neurons increases in compels animals
einstein had more
- glial cells = faster processing
sensory neurons
- carry incoming message from sensory receptors to the CNS
interneurons
- communicate within the CNS and process info btw incoming and outgoing messages
What doe the hypothalamus do?
- regulates body temp, helps govern the endocrine system, houses “reward centers”, part of it uses light cues to regulate sleep/wake cycles, controls MAINTENANCE functions like eating and drinking: HELPS MAINTAIN HOMEOSTASIS
What does the hippocampus do?
- creates new memories, integrates memories into a network of knowledge
( using things you learned in class ) - consolidates and stores memores

- symmetrical in some respects and have specialized abilities
What is the cerebral cortex?
- outer covering of 2 hemispheres of the brain
- great meaning “bark”
