GENERAL HISTOLOGY

Detailed explanation-1: -In the first decade of life, a child’s brain forms trillions of connections or synapses. Axons connect to dendrites, and chemicals called neurotransmitters help send messages (called “impulses”) across the resulting synapses.

Detailed explanation-2: -Memories are stored initially in the hippocampus, where synapses among excitatory neurons begin to form new circuits within seconds of the events to be remembered. An increase in the strength of a relatively small number of synapses can bind connected neurons into a circuit that stores a new memory.

Detailed explanation-3: -Synaptogenesis – the formation of synaptic connections – occurs as a growth cone reaches its target and transforms into the presynaptic terminal, a process that requires the reorganization of the actin cytoskeleton.
