Neuroscience
Component of a neuron that provides an insulating layer of fatty material.
Myelin sheath.
What are the breaks in the myelin sheath called?
Nodes of Ranvier.
What is semantic encoding?
Process of relating new information in a meaningful way to knowledge that is already stored in memory.
What is long-term potentiation?
Process whereby communication across the synapse between neurons strengthens the connection, making further communication easier.
Electrochemical action.
What is a Node of Ranvier?
Type of glial cell that forms myelin + speeds up the action potential + speeds up the conduction of info. up + down the axon.
What is visual imagery encoding?
Process of storing new information by converting it into mental pictures.
What are retrieval cues?
External information associated with stored information that helps bring that information to mind.
What is the Central Nervous System made up of?
Brain + spinal cord.
What are agonist drugs?
Drugs that increase action of neurotransmitters.
Process of categorizing information according to relationships among series of items.
What is the priming effect?
Enhanced ability to think of a stimulus as a result of recent exposure to the stimulus; less cortical activation (perceptual and conceptual priming).
Damage higher on spinal cord causes...?
More impairment.
What are glial cells?
What is the serial position effect?
First few and last few items in a series are more likely to be recalled than the items in the middle.
What is deja vu?
The illusion that one has previously had a given experience.
What is an axon's duty?
To transmit info. to other neurons, muscles, + glands.
What do Schwann cells do?
Build up myelin sheath.
What is an episodic buffer?
Automatically combines separate items into an integrated whole.
