The gate control theory of pain asserts that non-painful input closes the nerve "gates" to painful input, which prevents pain sensation from traveling to the central nervous system. In the top panel, the nonnociceptive, large-diameter sensory fiber (orange) is more active than the nociceptive small-diameter fiber (blue), therefore the net input ...
Pain theories. As long as humans have experienced pain, they have given explanations for its existence and sought soothing agents to dull or cease painful sensations. Archaeologists have uncovered clay tablets dating back as far as 5,000 BC which reference the cultivation and use of the opium poppy to bring joy and cease pain.

Linear and nonlinear control theory. The field of control theory can be divided into two branches: Linear control theory – This applies to systems made of devices which obey the superposition principle, which means roughly that the output is proportional to the input. They are governed by linear differential equations.
Sensory gating describes neural processes of filtering out redundant or irrelevant stimuli from all possible environmental stimuli reaching the brain. Also referred to as gating or filtering, sensory gating prevents an overload of information in the higher cortical centers of the brain. Sensory gating can also occur in different forms through ...
