If the higher brain centers become damaged, these primitive responses return because they are no longer being suppressed. Hope this helps to simplify the prior excellent answer. ...Read more

What do neurons do?

What do neurons do?

Neurons transmit sig: neurons transmits electric . They also process and transmit information between two cells. or introduce synapses, the specialized sites where neurons send and receive information from other cells, They also allow groups of neurons to coordinate complex processes.Without neurons, central nervous system does not function.
