The reason for detecting more frequent SP1 latency abnormalities is that the SP1 response is mediated to the ipsilateral trigeminal nucleus through a mono- or oligosynaptic circuit and is therefore quantitatively more sensitive, while the SP2 response is elicited by a more complex circuit with a more caudally located polysynaptic
chain of interneurons.
reflexes: the path is characterized by reflex arc of one or more interneurons.
2,12) It is generally believed to be a polysynaptic
reflex generated in the deep layers of the skin by activation of sweat glands via sudomotor sympathetic efferent fibers.
WBV has been shown to cause a tonic vibration reflex, which in turn leads to an increase in the recruitment of motor units through activation of muscle spindles and polysynaptic
In fact, Morrison is one of the very few exponents of mainstream comics today who actually challenges the medium in its own terms, taking established tropes like word and thought balloons and exposing them to polysynaptic
1997), and polysynaptic
inputs onto the LFS neurons from excitatory and inhibitory interneurons (Frost and Kandel, 1995).
l, 10) Field-potential recordings demonstrate that the H1 antagonist diphenhydramine decreases firing of polysynaptic
pathways in the lateral vestibular nucleus.
The barbiturates act throughout the central nervous system by directly inhibiting neuronal function at polysynaptic
and GABA-ergic sites.
In summary increase in the excitability of polysynaptic
spinal reflexes and startle responses was recorded, whereas other segmental and brain stem reflexes were normal.
The movement of the vibration plate during WBV exposure is postulated to activate both monosynaptic and polysynaptic
neural pathways adequate to generate a "tonic vibration reflex," similar to the stretch reflex.
All experiments were conducted in artificial seawater (ASW) containing high concentrations of divalent cations (Liao and Walters, 2002) to attenuate polysynaptic
Mechanical stimuli referring to muscle length are reflectively transferred through mono--and polysynaptic
pathways from the muscle spindles to the central nervous system (Cardinale and Bosco, 2003) for identification and appropriate response selection (Romaiguere et al.
