Neuro Ch 18

Front 1

In 1894, Ramón y Cajal first proposed that memory is stored as what?

Back 1

The strength of neuronal connections

Front 2

What is the term for a synapse if it can change the strength with which it affects its target?

Back 2

Plastic

Front 3

Who proposed this hypothesis?

If presynaptic axon is active and postsynaptic neuron is active - synapse is strengthened

If presynaptic axon is active but postsynaptic neuron is inactive - synapse is weakened

Back 3

Donald Hebb

Front 4

What hypothesis says that memory formation involves:

A brief transient memory storage (process)
A stable change in the nervous system (content)

Back 4

dual-trace hypothesis

Front 5

One hypothesis is that information is stored in what part of the brain but processed for memory storage in other brain areas?

Back 5

Cortex

Front 6

What is a brief increase of electrical stimulation that triggers thousands of axon potentials?

Back 6

Tetanus

Front 7

Induction of LTP activates what kind of signal for the presynaptic neuron to release more transmitter?

Back 7

retrograde

Front 8

An enriched environment that improves learning and memory, also produces what kind of new cells?

Back 8

Glial cells

Front 9

What is conditioned and unconditioned stimuli separated by a tiny delay, as in the eye-blink response. It occurs in cerebellum and does not involve the hippocampus.

Back 9

Delay conditioning

Front 10

What is a long delay between conditioned and unconditioned stimuli, relies on the hippocampus.

Back 10

Trace conditioning
