Electrophysiologic tests of the sacral neuromuscular system and its suprasegmental control may be divided into EMG and methods involving stimulation (i.e., evoked potential and sacral reflex testing). The latter group of methods tests the function of defined parts of the motor or sensory nervous system, or reflex arcs. There already is ample experience

During the last decade, somatosensory evoked potentials (SSEP) have become established as a practical method for monitoring the spinal cord during various surgical procedures where there is a risk of paraplegia, e.g., scoliosis surgery, thoracic aortic surgery, and neurosurgical procedures upon the spinal cord. However, it has also become apparent that

The recording of visual evoked potentials (VEPs) is an important means of obtaining reproducible, quantitative data on the function of the anterior visual pathways. In this review, the technical aspects of recording VEPs are briefly discussed, components of the VEPs are described, and the clinical uses of VEPs are considered.

This chapter will focus on the two auditory evoked potentials (AEP) most commonly used to assess the effects of general anesthetics on the brain, the auditory middle latency response (AMLR) and the 40 Hz auditory steady-state response (40 Hz-ASSR). We will review their physiological basis, the recording methodology, the effects of general anesthetics ...

Auditory evoked potentials (AEPs) are an electrical manifestation of the brain response to an auditory stimulus. Mid-latency auditory evoked potentials (MLAEPs) and the coherent frequency of the AEP are the most promising for monitoring depth of anaesthesia.

Noninvasive electrical stimulation of the human brain first was attempted in the 1950s. In the early 1980s, the first clinical application method of transcranial electrical stimulation was developed. Investigators in the mid-1980s showed that it was possible to stimulate the nerve and the brain using external magnetic stimulation (transcranial magnetic

The Evoked Potential in Pharmacopsychiatry
Neuropsychobiology, 2008Somatosensory, visual and auditory evoked potentials (EP) were recorded in different psychiatric populations before as well as during psychotropic drug treatment. Drug-free schizophrenic patients showed shorter latencies, smaller amplitudes and an increased intraindividual variability in their EP than controls.

The evoked potential was studied in Macaca speciosa before and after they received a lesion inducing neglect. Significant evoked potential changes associated with neglect were seen only in late components (N2, P3). These observations support the hypothesis of the arousal-attention mechanism of neglect.

Auditory evoked potentials (AEPs) have become an integral part of the current otologic/audiologic test battery. With these techniques, synchronous neural activity can be examined from the peripheral end organ of hearing up to the cortical structures responsible for audition.

Evoked potentials and psychopathy
International Journal of Psychophysiology, 1989All previous studies which have assessed evoked potentials (EPs) in psychopathic populations are critically reviewed. Three main themes emerge from this review. Firstly early EP studies suggest a dysfunctional arousal system at a brainstem or parietal cortex level in psychopaths.
