Our findings therefore suggest that the ability of neurotrophic factors to stimulate axon and dendrite growth may strongly depend on whether a neuron is an axonal or dendritic growth state, and raise the question of the identity of the extracellular signal that induces a dendritic growth mode (Goldberg et al. With increasing age, dendrites shrink, their branches become less complex, and they lose dendritic spines, the tiny protuberances that receive chemical signals. The myelin sheath that surrounds and protects nerve fibers wears down, which can slow the speed of communication between neurons. Age is also the biggest risk factor for many brain diseases, most of which affect brain structure and function. Brain Res.
