|
Somatic intervention
|
alteration of a structure or function to see how brain behavior is altered, manipulating the body to affect behavior
- Ex) does giving a patient who suffers from depression Prozac improve their symptoms? |
|
|
Behavioral intervention
|
intervention in a behavior to see how structure or function is altered
Ex) does eating cheerios prevent heart disease |
|
|
Correlation
|
measures how much a body measure varies with a behavioral measure, does not imply causation.
|
|
|
Neural plasticity
|
the ability of the brain to be changed by the environment and experience.
Dendritic spines in the brain can change shape in minutes, change in neurons |
|
|
Amygdala
|
part of the brain responsible for motion, learning, social interaction
|
|
|
Levels of analysis
|
range from social interaction down to the molecular level
|
|
|
Reductionism
|
breaks a system down into smaller parts in order to understand it
|
|
|
Consciousness
|
the state of awareness of one’s own existence and experience
|
|
|
Neurons
|
nerve cells, make up the nervous system
|
|
|
Neuron doctrine
|
the brain is composed of independent cells and information is transmitted from cell to cell across synapses
|
|
|
Glial cells
|
provide support for neurons
|
|
|
Atrocyctes
|
star shaped cells with many processes, receive neuronal input and monitor activity
|
|
|
Microglia
|
small cells that remove debris from injured cells
|
|
|
Oligodendrocytes & Schwann cells
|
provide a myelin sheath to cells
|
|
|
Oligodendrocytes
|
found in the CNS and myelinate neurons in the brain and spinal cord
|
|
|
Schwann cells
|
myelinate neurons everywhere but the brain and spinal cord
|
|
|
Edema
|
swelling, how glial cells respond to injury (also how tumors form)
|
|
|
Nodes of ranvier
|
gaps between sections of myelin where the axon is exposed
|
|
|
- Myelin sheath
|
glial cells wrapped around axons for insulation
|
|
|
Axon hillock
|
a cone-shaped area of the cell body that gives rise to the axon (unmyelinated)
|
|
|
Dendritic spine
|
studded on the dendrites and increase surface area
|
|
|
- Synaptic vesicle
|
small spheres in presynaptic axon terminals that contain a neurotransmitter (a specialized chemical substance)
|
|
|
- Input zone
|
receives information from other cells through dendrites
|
|
|
- Integration zone
|
a cell body region where inputs are combined and transformed
|
