Brian  asked the Naked Scientists:
Hi Chris,

I would like to know if the memory cells in the brain die and if replaced how is the stored information transferred to the new cell.  Is the information stored in the form of proteins and if so how is the information retrieved.

regards Brian Whitmore
What do you think?

Brain tissue can respond to damage or loss of neurons in Alzheimer’s disease or after a stroke by expanding dendrites and fine-tuning connections between neurons. A damaged brain neuron can readjust to damage only if its cell body remains intact. If it does, regrowth can occur in dendrites and axons. When neurons are destroyed, nearby surviving neurons can compensate, in part, by growing new dendrites and connections.
