Research uncovers new insights into neuronal aging and rejuvenation

When a neuron ages, it loses synaptic connections with other neurons, it is less able to transmit nerve impulses, and its metabolism is also altered. This process of neuronal aging — inevitable with the passing of time — is particularly accelerated and becomes a risk factor in neurodegenerative pathologies such as Alzheimer's disease.
