Question

5. Which of the following is not true regarding neuronal circuits? a. in a diverging circuit, the nerve impulse form a single presynaptic neuron b. in convergence, several presynatic neurons synapse with a single c. in oscillatory circuits the incoming impulse stimulate the 1"t neuron which d. in parallel after-discharge circuit, a group of presynaptic cells stimulates a causes the stimulation of increasing numbers of cells along the circuit postsynaptic neuron stimulated the 2nd, etc; branches from later neurons synapse with earlier ones reverberating the impulse back and forth single neuron which synapses with a common postsynaptic cell mnoral cummation?

Answer 1

Statement D is incorrect regarding neuronal circuits.

In parallel after-discharge circuit,not a group of presynaptic cells, instead a single nerve fiber stimulates several neurons arranged in parallel arrays and this finally stimulate a common output cell.
