Answer:
synapses
Explanation:
Brain cells have the efficiency to talk to its nearby cells and thus send or receive pre informed signals across connections. This process of intra brain cell communication is called as synapses
As we grow our brain organizes the previously established synaptic pathways and shuts down less-active, inefficient synapses
Neurons (brain cells) preserve their most active connections with the nearby cells and thus lapse the remaining synapses
SIRP alpha protein (found on the surface of cells) helps in cementing the active synaptic connections between brain cells
