What is an on center, off surround ganglion receptive field?

Selecciona una de las siguientes respuestas posibles:

  • Increased brightness creates a stronger response when this is within the on center, but creates a stronger inhibitory response when within the off surround

  • Decreased brightness creates a stronger response when this is within the on center, but creates a stronger inhibitory response when within the off surround

  • Decreased brightness creates a stronger inhibitory response when this is within the on center, but creates a stronger response when within the off surround

  • Increased brightness creates a stronger inhibitory response when this is within the on center, but creates a stronger response when within the off surround

Why does lateral inhibition happen, function?

Selecciona una de las siguientes respuestas posibles:

  • Perception cares about both the contrast (edges) and properties that help determine edges, and the retinal image

  • Perception only cares about neither the contrast (edges) and properties that help determine edges, or the retinal image
