.Synapses in the brain are structures that allow nerve cells to connect with other neurons or cells like glands, with most synapses functioning through dendritic extensions. Dendritic extensions play a critical role in forming synaptic connections, and their loss naturally occurs during the aging process. This leads to weakened synaptic communication and consequently negatively impacts memory processes. It has been observed that older individuals with larger dendritic extension head diameters in the temporal cortex exhibit better episodic memory performance without being affected by extension density.
