The nuchocephalic reflex.
The nuchocephalic reflex, previously undescribed, was investigated in a controlled study of 146 subjects ranging in age from 11 hours to 94 years. In 110 subjects over 16 years of age, the presence of the reflex was correlated directly with evidence of diffuse cerebral dysfunction as measured by a shortened form of the Wechsler Adult Intelligence Scale. Thirty-six children were studied from the...
متن کاملThe Fontana paradoxical reflex?
This commentary describes the "deflation cough" caused by deep lung deflations. Deflation cough is a paradoxical reflex similar to that described by Henry Head in 1889 for lung inflations that probably is mediated by the same sensors and afferent fibers in the lungs and activated by gastroesophageal reflux. We discuss how this reflex must be self-limiting, the general role of paradoxical reflex...
متن کاملThe Babinski reflex.
The plantar response is a reflex that involves not only the toes, but all muscles that shorten the leg. In the newborn the synergy is brisk, involving all flexor muscles of the leg; these include the toe 'extensors', which also shorten the leg on contraction and therefore are flexors in a physiological sense. As the nervous system matures and the pyramidal tract gains more control over spinal m...
متن کاملThe reflex-free hull
We propose a hull operator, the reflex-free hull, that allows us to define a 3D analogue to bays in polygons. The reflex-free hull allows a rich set of topological types, yet for polyhedral input with n edges, it remains a polyhedral set with O(n) edges. This is in contrast to other possible hull definitions that give non-planar surfaces and higher combinatorial complexity. The reflex-free hull...
متن کاملThe Grasp Reflex and Moro Reflex in Infants: Hierarchy of Primitive Reflex Responses
The plantar grasp reflex is of great clinical significance, especially in terms of the detection of spasticity. The palmar grasp reflex also has diagnostic significance. This grasp reflex of the hands and feet is mediated by a spinal reflex mechanism, which appears to be under the regulatory control of nonprimary motor areas through the spinal interneurons. This reflex in human infants can be r...
