Owen Jones Flashcards
how signals in the brain represent out interpretations of the outside environment
Central-Peripheral Nervous System Division
Reactivation (Memory)
event triggers activity in cell assembly, because of strengthened connectivity, it is more likely to make the next one fire, i.e. it is easier to reproduce the pattern of activation.
Short Term Memory Storage
‘Reverberating’ activity in networks of neurons
Long-Term Memory Storage
Stored by changing the strength of connections between neurons in a network
Donald Hebb
proposed that long-term memory depends on changes in synaptic strength + when a post-synaptic and pre-synaptic neuron are active at the same time, the synapse between them is strengthened.
LTP
Long-Term Potentiation is an artificial strengthening of synapses with many of the properties predicted by Hebb.
LTP induction depends on…
activation of the NMDA receptor, and NMDA antagonists block learning
What does ZIP impact and how?
LTP maintenance, ZIP produces forgetting (reversal of both memory and LTP)
Binding
Cell Assembly
Memories are stored in cell assemblies = ensembles of neurons connected by synapses that have been strengthened in an LTP-like manner
