9] Basically, the causes of delirium are disruption of the central nervous system's polysynaptic pathways and changes in the balance between excitatory and inhibitory amino acids.
22), and localizes the topographically bilateral lateral caudal pons and/or bilateral lateral medulla and polysynaptic chain (23).
Depending on the number of synapses interposed on the trajectory reflex arc, reflexes are monosynaptic and polysynaptic.
Polysynaptic pathways modify the signals greatly and can cause complex reflex patterns e.
One way to assess the disorders of the sympathetic system is sympathetic skin response (SSR), which is a result of polysynaptic reflex arch activation.
Darkness transmitted to the hypothalamic suprachiasmatic nuclei by the retinohypothalamic tract activates a polysynaptic pathway, which leads to the release of noradrenaline and adenosine triphosphate (ATP) by the sympathetic nerve terminals that reach the pineal gland [18].
Monosynaptic and polysynaptic pathways have been shown to mediate TVR (Desmedt and Godeaux, 1980; Luo et al.
Nevertheless, WBV has been shown to activate the tonic vibration reflex, a polysynaptic reflex resulting in many small reflex contractions of the targeted musculature [16,17,19-22].
It is a muscle relaxant of central action that blocks polysynaptic reflexes and depresses the transmission of nerve impulses in spinal cord neurons, widely used in horses (8).
R2 is transmitted to the spinal tractus in the dorsolateral region of the pons and medulla oblongata before the fibers of the reflex pathway reach the caudal end of spinal trigeminal nuclei, and it is then transmitted to facial nucleus in reticular formation through polysynaptic medullar pathways.
These observations suggest that extensor spasms are mediated by polysynaptic pathways involving activation of organized interneuronal circuits located within the isolated spinal cord that are modulated similarly by both hip and knee proprioceptive inputs.
Muscle relaxant" medications may inhibit polysynaptic myogenic reflexes in animal models, but their analgesic properties for muscle pain are unrelated to relief of muscle spasm.
