A High-Speed Brain Speller using steady-State Visual evoked potentials
International Journal of Neural Systems, 2014Implementing a complex spelling program using a steady-state visual evoked potential (SSVEP)-based brain-computer interface (BCI) remains a challenge due to difficulties in stimulus presentation and target identification.

Evoked potentials in the hypothalamus
American Journal of Physiology-Legacy Content, 1959The distribution and some properties of the evoked potentials in the hypothalamus from stimulation of the sciatic nerve were investigated in 60 cats. In the posterior and lateral hypothalamus biphasic positive-negative responses of 7–10 msec. latency were found, while in the anterior and medial hypothalamus the stimuli evoked monophasic negative waves

Tobacco and Evoked Potential [PDF]
Science, 1973 Significant changes were found in two indices of the averaged visual evoked potentials in nine smokers after 12 and 36 hours of abstinence and after resumption of smoking. There was a decrease of the amplitude envelope accompanying withdrawal and an increase with resumption of smoking.

Classification of evoked or event-related potentials is an important prerequisite for many types of brain-computer interfaces (BCIs). To increase classification accuracy, spatial filters are used to improve the signal-to-noise ratio of the brain signals ...

Somatosensory evoked potentials
2019Somatosensory evoked potentials (SEPs) have been routinely used over the years to evaluate the somatosensory pathway and thereby supplement the diagnostic process when the history, neurologic examination, and imaging were not fully conclusive. The utilization of SEPs has become more popular in recent years despite the advance of imaging studies such as

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

A Study of Evoked Potentials From Ear-EEG
IEEE Transactions on Biomedical Engineering, 2013A method for brain monitoring based on measuring the electroencephalogram (EEG) from electrodes placed in-the-ear (ear-EEG) was recently proposed. The objective of this study is to further characterize the ear-EEG and perform a rigorous comparison ...

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.

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
