Physiological brain aging is characterized by a combination of synaptic pruning, loss of
cortico-cortical connections and neuronal apoptosis that provoke age-dependent decline of …

The human brain contains an intricate network of about 100 billion neurons. Aging of the
brain is characterized by a combination of synaptic pruning, loss of cortico-cortical …

While many structural and biochemical changes in the brain have previously been
