|
Declarative memory |
Episodic- specific exp Semantic- info we gather about specific people places maps concepts not linked to a particular learning experience
LT declarative memory is stored in the hippocampus |
|
|
Non dec- procedural memory |
Automatic movements: basal ganglia is resp for this Mediated by striatum and cerebellum Involves motor skill learning, classical conditioning, perceptual learning, and repetition priming |
|
|
Learning |
Ionic current flow is the means of signal(info) transmission to the brain AP transmits signal down axon Neurochemicals transmit the signal across the synapse allowing info transfer within neural circuit Axon potential does not change in strength |
|
|
Habituation |
Caused by decrease in neurotransmitter Reduction of a response to repeated harmless situation |
|
|
Sensitization |
Strong response to a stimulus will increase responses to other stimuli- caused by increase in Neuro trans -pairing stimulus with a stronger response Interneurons release seratonin at the axo axonic synapses When seratonin binds with the receptor proteins on the sensory axon terminal, K channels close. This delays repolarization causing AP to last longer Thus Ca++ enters, NT released Structural changes! |
|
|
Repetition of the process involved in sensitization will result in... |
Long term learning through structural changes to the neuron These changes occur through activation of a transcription factor |
|
|
Glutamate |
Excitatory neurotransmitter important in cognition and learning Glutamate receptors can be ionitropic or metabotropic |
|
|
NMDA |
Glutamate receptor that is metabotropic. Thought to be important in developing long term memories |
|
|
Amygdala |
Emotion |
|
|
Deficits in medial temporal lobe |
Deficits in hippocampus |
|
|
When learning something... |
Signals travel to entorhinal cortices, then to uncus then hippocampus, then fornix, then back to where it came from (aud or visual cortex) |
|
|
Short term memory |
Mediated by cortical processing- holds on to info for a few seconds |
|
|
Sylvia parietal temporal region |
Links phoneme representations with motor production Also called planum temporale on superior temporal plane |
