(20) Both logistic regression and recursive partitioning methods for discrimination were tried.
Reflexive
Definition:
(a.) Bending or turned backward; reflective; having respect to something past.

(4) It is concluded that TRH is a specific activator of enteric excitatory pathways and that duodenal inhibition seen in control animals is a consequence of gastro-duodenal inhibitory reflexes.
(5) We conclude that the rat somatosympathetic reflex consists of an early excitatory component due to the early activation of RVL-spinal sympathoexcitatory neurons with rapidly conducting axons and a later peak that may arise from the late activation of these same neurons as well as the early activation of RVL vasomotor neurons with more slowly conducting spinal axons.
(6) These later results suggest that dopamine agonists increase sensorimotor reactivity measured with acoustic startle by acting on sensory rather than motor parts of the reflex arc.

(9) These reflexes can function to limit forces applied to a leg and provide compensatory adjustments in other legs.
(10) The influence of vestibular dysfunction upon the vestibulospinal reflex (VSR) in two common peripheral syndromes was investigated by two types of posturographic examination: "static" posturography, recording and analyzing the postural sway in stance, and "kinetic" posturography, recording the stepping in place test.
