Unformatted text preview: The Law of Specific Nerve Energies states that any activity by a particular neuron always conveys the same kind of information. So, all neurons use action potentials for carrying information meaning that all neurons carry the same energy. The brain interprets action potentials from different systems as different kinds of information (ex. smell, taste, touch, sound, light). So according to the law of specific nerve energies, the origin of the sensation is not important. The pathway over which the sensory information is carried defines the nature of perception. The different qualities of a sense (ex. different colors of light) can be distinguished in two ways. The first is the firing rates of different kinds of neurons and the second is the timing of the firing of nearby neurons (aka the activity of groups of neurons). QuickTime and a TIFF (LZW) decompressor are needed to see this picture....
