Document Summary
The colours for traffic lights are the same all over the world (shapes may be different but same colours) Red for stopping because red is associated with danger (bright red blood) to. Physical stimulus is in our external world that we can measure objectively. Sensory receptors convert energy from internal or external world into neural signals. Light energy = electromagnetic radiation in a narrow bandwidth. A receptive field includes all the input into a cell. In the retina, a receptive field includes all the photo receptors that feed into a single ganglion cell. Within our retina, we have photo receptor cells that have varying densities, just like our skin cells on our fingers vs. our leg for example. When the face is in an upright position like normal, we"re able to pick up details that are relevant to decode a face. Nanometer = one billionth of a meter.
