Objective: Patients with depression show blunted amygdala hemodynamic activity to positive stimuli, including autobiographical memories. The authors examined the therapeutic efficacy of real-time functional MRI neurofeedback (rtfMRI-nf) training aimed at increasing amygdala’s response memories in patients depression. Method: In a double-blind, placebo-controlled, randomized clinical trial, unmedicated adults (N=36) were randomly assigned receive two sessions rtfMRI-nf either from (N=19) or...
Background Amygdala hemodynamic responses to positive stimuli are attenuated in major depressive disorder (MDD), and normalize with remission. Real-time functional MRI neurofeedback (rtfMRI-nf) offers a non-invasive method modulate this regional activity. We examined whether depressed participants can use rtfMRI-nf enhance amygdala autobiographical memories, ability alters symptom severity. Methods Unmedicated MDD subjects were assigned receive from either left (LA; experimental group, n =...
Amygdala hemodynamic responses to positive stimuli are attenuated in major depressive disorder (MDD) and normalize with remission. Real-time functional magnetic resonance imaging neurofeedback (rtfMRI-nf) training the goal of upregulating amygdala activity during recall happy autobiographical memories (AMs) has been suggested, recently explored, as a novel therapeutic approach that resulted improvement self-reported mood depressed subjects. In this study, we assessed possibility sustained...
The relationship between primary motor cortex and movement kinematics has been shown in nonhuman primate studies of hand reaching or drawing tasks. Studies have demonstrated that the neural activities accompanying immediately preceding encode direction, speed other information. Here we investigated imagined actual movement, i.e. clenching speed, EEG activity ten human subjects. Study participants were asked to perform imagine left right at various speeds. alpha (8–12 Hz) beta (18–28...
Real-time fMRI neurofeedback (rtfMRI-nf) is an emerging approach for studies and novel treatments of major depressive disorder (MDD). EEG performed simultaneously with rtfMRI-nf procedure allows independent evaluation brain modulation effects. Frontal asymmetry in the alpha band a widely used measure emotion motivation that shows profound changes depression. However, it has never been directly related to acquired data. We report first study investigating electrophysiological correlates...
It is of wide interest to study the brain activity that correlates control brain-computer interface (BCI). In present study, we have developed an approach image cortical rhythmic modulation associated with motor imagery using minimum-norm estimates in frequency domain (MNEFD). The distribution sources mu during online BCI was obtained MNEFD. Contralateral decrease (event-related desynchronization) and ipsilateral increase synchronization) are localized sensorimotor cortex a group human...
Advances in neuroelectric recordings and computational tools allow investigation of interactive brain activity connectivity a group subjects engaged social interactions.
Functional magnetic resonance imaging (fMRI) studies utilizing measures of hemodynamic signal, such as the blood oxygenation level-dependent (BOLD) have discovered that resting-state brain activities are organized into multiple large-scale functional networks, coined networks (RSNs). However, an important limitation available fMRI is signals only provide indirect measure neuronal activity. In contrast, electroencephalography (EEG) directly electrophysiological activity brain. little known...
Light pollution, a phenomenon in which artificial nighttime light (NTL) changes the form of brightness and darkness natural areas such as protected (PAs), has become global concern due to its threat biodiversity. With ongoing urbanization climate change, pollution status PAs deserves attention for mitigation adaptation. In this study, we developed framework evaluate PAs, using NTL time series data. First, classified (30,624) into three categories: non-polluted (5974), continuously polluted...
The long-lasting neuromodulatory effects of repetitive transcranial magnetic stimulation (rTMS) are great interest for therapeutic applications in various neurological and psychiatric disorders, due to which functional connectivity among brain regions is profoundly disturbed. Classic TMS studies selectively alter neural activity specific observe changes on nonperturbed areas infer underlying its changes. Less has been indicated direct measures and/or network how connectivity/network...
Functional near-infrared spectroscopy (fNIRS) has been increasingly employed to monitor cerebral hemodynamics in normal and diseased conditions. However, fNIRS suffers from its susceptibility superficial activity systemic physiological noise. The objective of the study was establish a noise reduction method for whole-head montage.We have developed an automated denoising fNIRS. A high-density montage consisting 109 long-separation channels 8 short-separation used recording. Auxiliary sensors...
The coupling between neural cellular activity and blood oxygen level-dependent (BOLD) signal is of critical importance to the interpretation fMRI. Largely unknown, however, degree which different neuronal events (i.e., excitation inhibition) maintain or disrupt neural–hemodynamic relationship, especially in humans. In present study, we compared local electroencephalographic (EEG) oscillations positive/negative BOLD responses simultaneously recorded data from healthy human volunteers...
