摘要: Early manifestations of brain aging have received much less attention than the drastic degeneration AD and MID. During nonpathological changes normal aging, systems differ in involvement neuron loss. Spatial learning can become impaired without evidence for loss, whereas eye-blink conditioning deficits are well correlated with Purkinje Glial activation, particular increased expression glial fibrillary acidic protein (GFAP), may be a factor synaptic plasticity. Lastly, it is discussed how developmental variations numbers cells ovarian oocytes factors outcomes that not under strict genetic control.
