tactile cutaneous stimulation conducted by A beta fibers inhibits pain, conducted by C fibers

proprioceptive stimulation conducted by A gamma fibers inhibits fast pain conducted by A ...fibers

presynaptic inhibition of pain is performed by descending hyperpolarizing on 2nd order

tactile cutaneous stimulation conducted by C fibers inhibits pain, conducted by A beta-fibers

fast pain fibers of the spinal cord liberate excitatory neurotransmitter glutamate

most of slow pain fibers finish in reticular formation, rectal area and perpendicular grey region

upon entering the spinal cord fast and slow pain fibers synapse with the same population of neurons

paleospinothalamic tract transmits impulses concerning quality, intensity and location of pain

lateral spinothalamic tract

same pathway as the sense of vibration and fine, precise touch

same pathway pathway as the input from thermoreceptors
