WebThe receptive field of a dorsal column nucleus has an inhibitory surround, which is a result of the indirect connections between mechanoreceptors and the dorsal column neuron via inhibitory interneurons. A) When no stimulus is present, … The receptive field, or sensory space, is a delimited medium where some physiological stimuli can evoke a sensory neuronal response in specific organisms. Complexity of the receptive field ranges from the unidimensional chemical structure of odorants to the multidimensional spacetime of human visual field, through the bidimensional skin surface, being a receptive field for touch perception. Receptive fields can positively or negatively alter the memb…
WebInformation from specific color cones can be selectively relayed to specific regions of a retinal ganglion cell's receptive field. All of the above are true, none is false. Because there are several different color types of cones, they are sensitive to dimmer illumination levels than is the population of rods.
