Different features are coded by the activity of different places. Where the stimulated nerve cells are in the retina tells you where the object is in space, since light travels in a straight line.

Different features are coded by the rate of firing of a neuron. Brightness of a light is coded in the firing rate of a group of neurons: population coding/pattern doing. Different features re coded by the pattern of stimulation across a group of neurons. Explain the different types of sensory energy in the different modalities, and which physical characteristics correspond to which psychological characteristics. Transduction: sense organs convert energy from environment events into neural activity (electrical signals)
