What are neurotransmitters?
The chemicals belonging to nervous system are known as neuro transmitters. In nervous system, the signals go from one place to another place. The nervous cells are known as neurons. These neurons achieve signals from other cells through dentries. Oxygen is useful to return the signals back to cells. The signal from Ogden to another cell passes through the empty place called synapse, which is lie in between the two cells. The chemicals that are useful to send the information from synapse are called neurotransmitters. Actually neuro transmitters are the chemicals which are useful to send messages from one cell to another. Up to 20th century, scientists thought that the information from synapse is transmitted through electricity. In 1921, German pharmacologist Otto Louie (1873-1934) determined that neurons transmit information by releasing chemicals. He discovered the neurotransmitter called acetylcholine. But some neurons pass information through electrical synops.
