Population Coding
There are a variety of neurons types needed to code for specific patterns of a stimulus. These neurons work together to encode information which cannot be done precisely by one neuron type alone. This principle is summarized by the theory of across-neuron response pattern (ANRP). Which states a stimulus will activate a uniquely different set of patterns to discriminate between another stimuli. This is depicted by the absolute difference of neural mass.
Somatosensory system codes for the experience of three main types of exteroceptive input; mechanical stimuli (touch), thermal stimuli (temperature) and nociceptive stimuli (pain). Which all require a distinct process. Conscious exteroceptive input is often split into three neuron types. Nociceptive specific neurons are located in the furthest dorsal part of the dorsal horn. These neurons respond to noxious input and signal the presence of pain. Wide Dynamic range neurons are located deeply in the dorsal horn too. Respond to frequency and intensity of a stimulus which signals pain. These response characteristics can be altered in certain input similar to the process of memory. Enkephalinergic interneurons are located in the substantia gelatinosa of the dorsal horn. They’re involved in …show more content…
The retina contains three receptors which code different portions of the color spectrum. The receptors are short-wavelength, Middle-wavelength and long-wavelength cone receptors. Which code for blue green and red wavelengths respectively. Different ratios of wavelengths represent unique colors.
Across-neuron response patterns is said to constitute the fundamental language of the nervous system. Population coding provides detailed processing for stimulus. This is important for humans as it can hold information such as which foods are ripe enough to eat or warn them if they’re standing close to something which will burn
