From which form of declarative memory is retrieval of information often more difficult? Why?
3 marks
AnswerRetrieval of information is often more difficult from episodic memory. There memories are less well learned, and are more context dependent and state-dependent in nature.

•Review the function of a neuron•Explain the role of the neuron in memory formation informed by the work of E. Richard Kandel!

Revision - The Neuron

Kandel found that any experience resulting in memory produces physical changes in the brain at the neuronal level, changes in structure and function of neurons.

Kandel’s Research on the role of neurons
Eric Kandel studies the sea slug Aplysia for the following reasons:•Very simple nervous system•Only 20,000 neurons•Largest neurons in the world and can be seen with the naked eye
Friday, 13 April 2012
Studied simple learning and remembering of the gill-withdrawal reflex of Aplysia
Kandel’s experiments
Observed changes at the synapse (i.e. point of communication by adjacent neurons) in the structure and function of neurons in three ways:•Release extra neurotransmitter•Increase number of receptor sites•Growth of new synapses
These changes are called collectively Long Term Potentiation
