Term
|
Definition
The ability to recognize stimuli that have been perceived before
-caused by changes in sensory systems |
|
|
Term
| Stimulus-response learning |
|
Definition
Learning to make a particular response in the presence of a specific stimulus
-caused by changes b/w sensory and motor systems
-includes classical and instrumental conditioning |
|
|
Term
|
Definition
Learning to make a new response
-caused by changes in the motor systems |
|
|
Term
|
Definition
| Learning relationships b/w individual stimuli |
|
|
Term
|
Definition
On a cellular level, a synapse is strengthened that is repeatedly active when the postsynaptic neuron is firing
-related to classical conditioning |
|
|
Term
| Long-term potentiation (LTP) |
|
Definition
| An increase in the excitability of a neuron to a specific synaptic input that is caused by consistent activity of that input |
|
|
Term
| Which NT is majorly involved in LTP? |
|
Definition
|
|
Term
|
Definition
Ionotropic glutamate receptor that is responsible for LTP
-controls a calcium (Ca+) channel that is normally blocked by Mg2+ (Magnesium) ions |
|
|
Term
| Associative long-term potentiation |
|
Definition
| An LTP that strengthens a weak synapse because it was stimulated simultaneously with a strong one |
|
|
Term
|
Definition
| An AP that sends a depolarizing signal up the dendrite |
|
|
Term
|
Definition
Ionotropic glutamate receptor that produces EPSPs when open
-controls a Sodium (Na+) channel |
|
|
Term
| Long-term depression (LTD) |
|
Definition
A decrease in the excitability of a neuron to a particular synaptic input
-caused by stimulation of the terminal when the postsynaptic membrane is hyperpolarized |
|
|
Term
| Why does perceptual learning occur? |
|
Definition
| As a result of changes in synaptic connections w/in the sensory association cortex |
|
|
Term

|
Definition
|
|
Term
|
Definition
| Involved in reinforcing effects/reward signal |

|
|
Term
|
Definition
| Process by which short-term memories are converted into long-term memories |
