WebReceptive Fields. Different neurons in the visual system respond to light falling within different more-or-less well-defined areas of the retina, and have a distinguished point where the response sensitivity is greatest. This area is called the receptive field of the neuron, and the point of peak sensitivity is called the receptive field center. WebThe base rate for ganglion cell firing under uniform lighting conditions (i.e. equal stimulation of the center & surround) is ~20-50 action potentials per second, so you actually get a reduction in firing if the OFF-center cell is stimulated in the center, but an increase in firing if the ON-center cell is stimulated in the center. unable to locate package hydra in termuxWebThis video describes the definition of receptive fields and details the neurotransmitters behind the transduction of light.
