Transcranial ultrasound neuromodulation of the thalamic visual pathway in a large animal model and the dose-response relationship with MR-ARFI

Scientific Reports, 2022
Neuromodulation of deep brain structures via transcranial ultrasound stimulation (TUS) is a promising, but still elusive approach to non-invasive treatment of brain disorders.

Efficient Low-Frequency SSVEP Detection with Wearable EEG Using Normalized Canonical Correlation Analysis

Sensors, 2022
Recent studies show that the integrity of core perceptual and cognitive functions may be tested in a short time with Steady-State Visual Evoked Potentials (SSVEP) with low stimulation frequencies, between 1 and 10 Hz.

The Influence of the Modulation Index on Frequency-Modulated Steady-State Visual Evoked Potentials

Frontiers in Human Neuroscience, 2022
Based on increased user experience during stimulation, frequency-modulated steady-state visual evoked potentials (FM-SSVEPs) have been suggested as an improved stimulation method for brain-computer interfaces.

Adaptation in the visual cortex: influence of membrane trajectory and neuronal firing pattern on slow afterpotentials. [PDF]

PLoS ONE, 2014
The input/output relationship in primary visual cortex neurons is influenced by the history of the preceding activity. To understand the impact that membrane potential trajectory and firing pattern has on the activation of slow conductances in cortical ...

The steady-state visual evoked potential in vision research : a review

, 2015
Periodic visual stimulation and analysis of the resulting steady-state visual evoked potentials were first introduced over 80 years ago as a means to study visual sensation and perception. From the first single-channel recording of responses to modulated

Learning alters theta amplitude, theta-gamma coupling and neuronal synchronization in inferotemporal cortex [PDF]

, 2011
Background: How oscillatory brain rhythms alone, or in combination, influence cortical information processing to support learning has yet to be fully established.

Effects of high frequency-repetitive transcranial magnetic stimulation on pattern visual evoked potential and vasoactive intestinal peptide expression in visual cortex of rats with amblyopia

, 2022
Abstract Aim To explore the effects of high frequency-repetitive transcranial magnetic stimulation (hf-rTMS) on pattern visual evoked potential (PVEP) and vasoactive intestinal peptide (VIP) expression in visual cortex of rats with amblyopia and to preliminarily discuss the underlying mechanism of action.

Bimodal sensory integration in migraine: A study of the effect of visual stimulation on somatosensory evoked cortical responses

, 2022
Background: Merging of sensory information is a crucial process for adapting the behaviour to the environment in all species. It is not known if this multisensory integration might be dysfunctioning interictally in migraine without aura, where sensory ...

Event-related alpha suppression in response to facial motion [PDF]

, 2014
This article has been made available through the Brunel Open Access Publishing Fund.While biological motion refers to both face and body movements, little is known about the visual perception of facial motion. We therefore examined alpha wave suppression
