have shown that both calorie restriction and intermittent fasting along with vitamin and mineral intake, increase resistance to disease, extend lifespan, and stimulate production of neurons from stem cells.

Physical exercise may also have beneficial effects on neuron regeneration by stimulating regeneration of brain and muscle cells via activation of stress proteins and the production of growth factors. But again, additional research suggests that not all exercise is equal. Interestingly, some researchers found that exercise considered drudgery was not beneficial in neuronal regeneration, but physical activity that was engaged in purely for fun, even if equal time was spent and equal calories were burned, resulted in neuronal regeneration.

Neurons exist in a number of different shapes and sizes and can be classified by their morphology and function. The anatomist Camillo Golgi grouped neurons into two types; type I with long axons used to move signals over long distances and type II without axons. type I cells can be further divided by where the cell body or soma is located. The basic morphology of type I neurons, represented by spinal motor neurons, consists of a cell body called the soma and a long thin axon which is covered by the myelin sheath. Around the cell body is a branching dendritic tree that receives signals from other neurons. The end of the axon has branching terminals (axon terminal) that release transmitter substances into a gap called the synaptic cleft between the terminals and the dendrites of the next neuron.
