A Stimulus to Which Afferent Neurons X,Y and Z Are

question 93

Multiple Choice

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?

• A)Neuron Y activates inhibitory interneurons that directly inhibit the synaptic transmission of neurons X and Z
• B)Neuron Y directly inhibits the synaptic transmission of neurons X and Z
• C)The synaptic activity of neuron Y is not affected by action potentials in neurons X and Z
• D)Both neuron Y activates inhibitory interneurons that directly inhibit the synaptic transmission of neurons X and Z and the synaptic activity of neuron Y is not affected by action potentials in neurons X and Z are correct
• E)Both neuron Y directly inhibits the synaptic transmission of neurons X and Z and the synaptic activity of neuron Y is not affected by action potentials in neurons X and Z are correct
