Detailed explanation-1: -This neuron would not be able to recharge the signal. This neuron would not be able to integrate information from numerous synapses.
Detailed explanation-2: -Neuronal apoptosis, a form of programmed cell death or cellular suicide, has also been demonstrated in a variety of cerebral ischemia models. Apoptosis is characterized by chromatin condensation, involution of the cell membrane, swelling of mitochondria, and cellular shrinkage.
Detailed explanation-3: -Nerve Cells Do Not Renew Themselves Yet, nerve cells in your brain, also called neurons, do not renew themselves. They do not divide at all. There are very few exceptions to this rule – only two special places in the brain can give birth to new neurons. For the most part though, the brain cannot replenish dead neurons.
