Presynaptic neurons generate nerve impulses (action potentials) which are transmitted to the postsynaptic neuron via synapses (junctions). Presynaptic neurons release neurotransmitters in the synapse which bind to the specific receptors on the postsynaptic neuron. A diagrammatic figure showing connectivity of neurons in a neural circuit is given below. The dendrites and cell body of a postsynaptic neuron (A) receive

Options

  1. ANeuron A will generate an action potential if only neurons 1 and 5 release Ach on it.
  2. BNeuron A will generate an action potential if neuron 1 releases Ach and at the same time neurons 2,3 , and 4 r
  3. CNeuron A will not generate an action potential but instead gets inhibited if neuron 1 releases Ach and at the
  4. DAll of the above.

Correct answer

C. Neuron A will not generate an action potential but instead gets inhibited if neuron 1 releases Ach and at the
