Little is known about the way speech in noise is processed along the auditory pathway. The purpose of this study was to evaluate the relation between listening in noise using the R-Space system and the neurophysiologic response of the speech-evoked auditory brainstem when recorded in quiet and noise in adult participants with mild to moderate hearing loss and normal hearing.

Intraoperative neurophysiologic monitoring was performed in a patient by somatosensory evoked potential, motor evoked potential and free-running electromyography with intraoperative stimulation. It was verified that after decompression, there was an increase in the amplitude of motor evoked potential responses, showing an immediate improvement of the treated levels. Intraoperative neurophysiolo...

A SPECT (single photon emission computed tomography using Tc-99m HMPAO) study of brain with segmental quantitative analysis was conducted to access the cerebral perfusion in cases of Downs syndrome (DS). Varying level of brain hypo-perfusion was documented, probably explaining the neurophysiologic basis of cognitive and neuropsychological deficits, which are not well understood in DS.

Application of acupuncture methods goes back centuries. Today, there is much scientific research and many approaches to explain the mechanism of acupuncture. Among these approaches, the most popular one is the neurophysiologic approach. In this paper, we explain the series of events that follow the insertion of acupuncture needles under the headings of local reactions; regional reflexes related...

Within philosophical literature, higher-level cognitive concepts such as free will, authorship of actions, and conscious control are often questioned. Neurological and biochemical mechanisms underlying human behavior provide alternative explanations of action. Reduction of cognitive states to neurophysiologic states shows that higher-level cognitive concepts in principle can be eliminated, repl...
