Abstract: Aging and the effects of damage on the brain are considered on the basis of the Hopfield model. As the damage to the brain or the debility of neurons is increased by aging, a sudden change similar to critical phenomena is observed in the ability to retrieve information or in recognition. This type of critical behavior is very similar to the percolation phenomenon in physics. Furthermore the relearning effect, which corresponds to so-called rehabilitation, is discussed.
