Popis: Electron microscopy was used to study structural changes of synapses in sensorimotor, parietal, limbic cortical areas, hippocamp, blue spot and hypothalamus of old Wistar rats, aged 28-30 months. Polymorphism of ultrastructural changes in neuronal and synapse processes and individual variability of these shifts in the brain of old rats have been revealed. The predominant damage of post-synaptic synapse components with ageing is demonstrated. Along with dystrophic and destructive changes in pre- and post-synaptic parts of the contact, signs of compensatory adaptive resettings in inter-neuronal links have been detected.
