A stimulus to which afferent neurons X,Y and Z are sensitive is detected in the middle of Y's receptive field.The same stimulus simultaneously activates receptors on the periphery of the receptive fields of X and Z.Which of the following is likely to be true?

Lateral inhibition is a common mechanism in sensory systems. In this case, neuron Y is likely to activate inhibitory interneurons that directly inhibit the synaptic transmission of neurons X and Z. This would prevent neurons X and Z from responding to the stimulus, even though their receptive fields are partially activated.
