Neocortex Flashcards
Where is recognition memory believed to be stored?
In the perihinal cortex.
Where is the perihinal cortex?
An area of the cortex immediately beside the entorhinal cortex.
What is the capacity of recognition memory?
It is almost limitless
Which requires fewer connections, recognising familiarity or recalling a memory?
Recognising familiarity.
What is the following formula representing:
P=0.023cN^2
Memory capacity for a recognition network.
Where c is the fraction of pairs that are connected and N is the number of neurons.
How does the cortex learn memories?
It tends to learn memories slowly, in a way that discovers overlaps and exploits them for learning.. As opposed to the hippocampus which is capable of storing memories very quickly with little chance of overlap.
What is the connection between memories in the hippocampus and the cortex?
It is believed memories are first stored in the hippocampus and over time if they are important they are learnt from their to neocortex where they are are stored in a rich, interconnected way.
