Attentional M100 gain modulation localizes to auditory sensory cortex and is deficient in first‐episode psychosis

Human Brain Mapping, Volume 44, Issue 1, Page 218-228, January 2023., 2023
The use of magnetoencephalography and the Human Connectome Project multimodal parcellation revealed precise cortical areas underlying attention modulation of auditory sensory activity in healthy individuals and impairments in early psychosis. The sensory reduction and attention modulation impairment indicate pathophysiology proximal to disease onset ...

The role of physiological complexity changes in resting-state EEG in clinical effectiveness of rTMS and tDCS in treatments of resistant depression [PDF]

Frontiers in Psychology, section Neuropsychology,Volume 10, Article 2923. 10 December 2019, 2019
The present literature about possible mechanisms behind the effectivity of noninvasive electromagnetic stimulation in major depressive disorder (MDD) is not very rich. Despite extensive research in applications for clinical practice, the exact effects are yet not clear.

Differences in functional connectivity distribution after transcranial direct‐current stimulation: A connectivity density point of view

Human Brain Mapping, Volume 44, Issue 1, Page 170-185, January 2023., 2023
In this manuscript, we develop a method utilizing the distribution of resting‐state fMRI connectivity measurements to study the effect of a direct stimulation. The method can drastically reduce the number of multiple comparisons compared with edge‐wise analysis.

Generalized models for quantifying laterality using functional transcranial Doppler ultrasound

Human Brain Mapping, Volume 44, Issue 1, Page 35-48, January 2023., 2023
Transcranial functional Doppler Ultrasound has been used to assess brain lateralization, but the methods used to extract a laterality index (LI) have involved simple averaging over a period of interest. Here, we compare results from that method with results from a generalized linear models (GLM) approach similar to that used in functional magnetic ...

Brain Modeling for Control: A Review [PDF]

, 2022
Neurostimulation technologies have seen a recent surge in interest from the neuroscience and controls communities alike due to their proven potential to treat conditions such as Parkinson's Disease, and depression. The provided stimulation can be of different types, such as electric, and optogenetic, and is generally applied to a specific region of the

Repetitive transcranial magnetic stimulation and epilepsy: A brief essay [PDF]

arXiv, 2022
During the last three decades, many studies have been conducted in the field of treatment with non-invasive methods. In this way, researchers try to use alternative methods including the use of electromagnetic waves in the treatment of diseases. As a result, the therapeutic use of electromagnetic waves in the treatment of neurological diseases has made

Toward Semantic Publishing in Non-Invasive Brain Stimulation: A Comprehensive Analysis of rTMS Studies [PDF]

arXiv, 2023
Noninvasive brain stimulation (NIBS) encompasses transcranial stimulation techniques that can influence brain excitability. These techniques have the potential to treat conditions like depression, anxiety, and chronic pain, and to provide insights into brain function.

Motor cortical excitability and pre‐supplementary motor area neurochemistry in healthy adults with substantia nigra hyperechogenicity

Journal of Neuroscience Research, Volume 101, Issue 2, Page 263-277, February 2023., 2023
Substantia nigra (SN) hyperechogenicity, viewed with transcranial ultrasound, is a risk marker for Parkinson's disease. SN hyperechogenicity in healthy older adults is associated with changes in the excitability of specific motor cortical circuitry. These changes are unrelated to glutamate levels in the pre‐supplementary motor area (pre‐SMA).

Home‐Based Tele‐tDCS in Amyotrophic Lateral Sclerosis: Feasibility, Safety, and Preliminary Efficacy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited treatment options. Transcranial direct current stimulation (tDCS) shows promise as a neuromodulatory intervention in various neurological disorders, but its application in ALS, particularly in a remote, home‐based format, remains underexplored.

Review on Biophysical Modelling and Simulation Studies for Transcranial Magnetic Stimulation [PDF]

, 2020
Transcranial magnetic stimulation (TMS) is a technique for noninvasively stimulating a brain area for therapeutic, rehabilitation treatments and neuroscience research. Despite our understanding of the physical principles and experimental developments pertaining to TMS, it is difficult to identify the exact brain target as the generated dosage exhibits ...
