Some neurons release the neurotransmitter glycine onto motor neurons. If these nerves are removed glycine is no longer released onto the motor neurons, and after a period of time the motor neurons become extremely sensitive (i.e., more responsive) when glycine is applied onto the motor neurons. Based on this information, what can most likely account for this enhanced effect? agonism antagonism O upregulation downregulation
