In our brain, there are around 10 billion neurons and the neural synapses are the basic and connection units transferring the information between them. The neural transmitters, released by presynaptic neurons, diffuse into the synaptic cleft and then bind to the corresponding receptors on postsynaptic neurons, thereby regulating their neuronal activity and accomplishing the information tra... more |
