Airborne Ultrasonic Tactile Display Brain-computer Interface -- A Small Robotic Arm Online Control Study [PDF]

open access: yesarXiv, 2015
We report on an extended robot control application of a contact-less and airborne ultrasonic tactile display (AUTD) stimulus-based brain-computer interface (BCI) paradigm, which received last year The Annual BCI Research Award 2014. In the award winning human communication augmentation paradigm the six palm positions are used to evoke somatosensory ...

Somatosensory evoked potentials in hysterical paraplegia

open access: yesSurgical Neurology, 1985
Somatosensory evoked potentials were determined in three patients with hysterical neurologic deficits after minor trauma. In each case the patient denied any sensation of the stimulus in the affected extremity; however, normal evoked potentials were recorded. Objective evidence of the hysterical nature of the neurologic deficit was, therefore, provided.

Benign Idiopathic Myoclonus: A New Clinical Entity?

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus is a brief shock‐like, involuntary movement, which can be distinguished in physiologic, essential, epileptic, and symptomatic, according to its etiology. Physiologic myoclonus typically occurs in healthy people without disability or progression.

Towards direct neuronal current imaging via ultra-low-field MR [PDF]

open access: yesarXiv, 2019
The feasibility of using ultra-low-field magnetic resonance (ULF MR) for direct neuronal current imaging (NCI) is investigated by phantom measurements. The aim of NCI is to improve the current localization accuracy for neuronal activity of established methods like electroencephalography (EEG) or magnetoencephalography (MEG) (~1 cm).

Obtaining single stimulus evoked potentials with Wavelet Denoising [PDF]

open access: yesPhysica D, 2000; 145: 278-292, 2000
We present a method for the analysis of electroencephalograms (EEG). In particular, small signals due to stimulation, so called evoked potentials, have to be detected in the background EEG. This is achieved by using a denoising implementation based on the wavelet decomposition.

Unmasking of latent synaptic connections in the cortex of the rat, elicited by a facial nerve transection [PDF]

open access: yes, 2001
Peripheral nerve injury elicits plastic changes in the cortex, resulting in reorganization of the somatotopic representation maps. These processes begin within minutes after nerve injury, and last for weeks.

Oscillatory Coupling Between Thalamus, Cerebellum, and Motor Cortex in Essential Tremor

open access: yesMovement Disorders, EarlyView.
Abstract Background Essential tremor is hypothesized to emerge from synchronized oscillatory activity within the cerebello‐thalamo‐cortical circuit. However, this hypothesis has not yet been tested using local field potentials directly recorded from the thalamus alongside signals from both the cortex and cerebellum, leaving a gap in the understanding ...

Dynamic and integrated mechanical movements of a rat brain associated with evoked potentials [PDF]

open access: yesarXiv, 2014
By using a piezoelectric sensor, it was demonstrated that the visual evoked potential of a rat brain was accompanied by mechanical movements of the brain when it was excited. A phase of upward movement was found to be followed by a phase of downward movement.
