Conditionally Exponential Prior in Focal Near- and Far-Field EEG Source Localization via Randomized Multiresolution Scanning (RAMUS) [PDF]
arXiv, 2021 In this paper, we focus on the inverse problem of reconstructing distributional brain activity with cortical and weakly detectable deep components in non-invasive Electroencephalography. In particular, we aim to generalize the previously extensively used conditionally Gaussian prior (CGP) formalism to achieve distributional reconstructions with higher ...

Electrophysiological evaluation of chronic neuropathic pain of spinal cord injury origin [PDF]
The Indian Journal of Neurotrauma, 2010 The chronic neuropathic pain of spinal cord injury origin has been shown to be related to permanent neurochemical changes in the dorsal horn neurons thus producing spontaneous discharges of central nociceptive neurons resulting in chronic pain.

A 20-Channel Magnetoencephalography System Based on Optically Pumped Magnetometers [PDF]
, 2017 We describe a multichannel magnetoencephalography (MEG) system that uses optically pumped magnetometers (OPMs) to sense the magnetic fields of the human brain. The system consists of an array of 20 OPM channels conforming to the human subject's head, a person-sized magnetic shield containing the array and the human subject, a laser system to drive the ...

Bayesian Multi--Dipole Modeling of a Single Topography in MEG by Adaptive Sequential Monte Carlo Samplers [PDF]
Inverse Problems 30 (2014) 045010, 2013 In the present paper, we develop a novel Bayesian approach to the problem of estimating neural currents in the brain from a fixed distribution of magnetic field (called \emph{topography}), measured by magnetoencephalography. Differently from recent studies that describe inversion techniques, such as spatio-temporal regularization/filtering, in which ...

Airborne Ultrasonic Tactile Display BCI [PDF]
Brain-Computer Interface Research - A State-of-the-Art Summary 4.
SpringerBriefs in Electrical and Computer Engineering. 2015. p. 57-65, 2015 This chapter presents results of our project, which studied whether contactless and airborne ultrasonic tactile display (AUTD) stimuli delivered to a user's palms could serve as a platform for a brain computer interface (BCI) paradigm. We used six palm positions to evoke combined somatosensory brain responses to implement a novel contactless tactile ...

Airborne Ultrasonic Tactile Display Brain-computer Interface Paradigm [PDF]
, 2014 We study the extent to which contact-less and airborne ultrasonic tactile display (AUTD) stimuli delivered to the palms of a user can serve as a platform for a brain computer interface (BCI) paradigm. Six palm positions are used to evoke combined somatosensory brain responses, in order to define a novel contact-less tactile BCI.
