Question

Quizplus · Accepted Answer

Receptive fields of sensory neurons have a characteristic shape with excitatory and inhibitory regions. These regions determine how the neuron responds to different types of stimuli. Some regions are sensitive to pressure or touch, while others are sensitive to temperature or pain. These regions can also be inhibitory, meaning that they suppress the neuron's response to certain stimuli. Receptive fields can vary in size and shape, depending on the location of the neuron on the skin.
