Altered frontal lobe activity and executive control associated with working memory (WM) dysfunction are recognized as core deficits in schizophrenia. These impairments have been discussed as being associated with deficits in self-regulated action monitoring and anticipatory action plan generation. To study electrophysiological correlates of executive control -- specifically action monitoring an...

Manic (n = 26), schizophrenic (n = 26), and normal (n = 25) subjects were examined with a digit span distraction task and with a reality monitoring task. All subjects were tested twice at a 4-day interval, and a clinical assessment of thought disorder was conducted both times on the patients. We found that reality monitoring, distraction task performance, and clinical thought disorder were all ...

BACKGROUND CONTEXT Intraoperative somatosensory evoked potential (SSEP) monitoring has been shown to reduce the incidence of new postoperative neurological deficits in scoliosis surgery. However, its usefulness during cervical spine surgery remains a subject of debate. PURPOSE To determine the utility of intraoperative SSEP monitoring in a specific patient population (those with cervical radi...

The authors describe 3 theoretical accounts of age-related increases in falsely remembering that imagined actions were performed (A. K. Thomas & J. B. Bulevich, 2006). To investigate these accounts and further explore age-related changes in reality monitoring of action memories, the authors used a new paradigm in which actions were (a) imagined only, (b) actually performed, or (c) both imagined...

Intraoperative neurophysiologic monitoring (IONM), including somatosensory evoked potential (SEP), and transcranial electric motor (MEP), had been utilized during brain or spine surgery to identify neurologic deficits. But some deficits, such as abulia, could not be detected through routine IONM. MEP SEP might monitor non-motor sensory lesions surgery. We experienced a 72-year-old case with an ...

Neurocognitive disorders in the elderly are on rise all over world. Neuropsychological assessment is vital to monitoring progress of cognitive deficits. Over years, there has been significant development neuropsychological predict and progression MCI dementia. One such area recent advancement field neuropsychology technology-based assessment. There several types assessments available based type...

BACKGROUND This is a prospective observational study examining the use of a surgeon-driven intraoperative neurophysiologic monitoring system. Intraoperative neurophysiologic monitoring is becoming the standard of care for spinal surgeries with potential post-operative neurologic deficits. This standard applies to both adult and pediatric spinal surgery, but a shortage of appropriately trained a...
