Real-time control of a robot using brain activity
… which may impair ones movement but spares the brain which may remain capable of performing cognitive tasks. Aim: This project aims to develop a proof-of-concept system: a small robot that can be controlled by brain activity through a brain-computer interface. The user will be able to have …

Brain Activity in College Students with the Broad Autism Phenotype
<p>Abstract</p> <p>This study examined brain activity in college students with the broad autism phenotype (BAP) while viewing facial expressions. Quantitative Electroencephalogram assessments were conducted in the temporal lobe area in the brains of 38 college students declared as Science, …

Task-Dependent Oscillatory Brain Activity During Oculomotor Delayed Response Task
… the Non–Match condition had lower alpha activity during the delay period at each midline electrode site reflecting the higher cognitive effort required.

Information Processing and Regional Brain Activity in Anxiety and Depression
… and anxious), and control college students. More brain activity was observed over the left hemisphere. This asymmetry increased with anxiety. Low-depression/high-anxiety women showed greater left hemisphere activity. Gender was also involved in other significant interactions. Results indicate that …

Optical and computational approaches for mapping brain activity and structure
… sets that can provide deeper insights into the brain. While there is no universal agreement as to what data sets are needed to fully reveal the underlying principles of brain computation, neurons will certainly serve as an important layer to study the brain considering their discreteness and …

Response variability in ADHD: exploring the possible role of spontaneous brain activity
Attention-Deficit/Hyperactivity Disorder (ADHD) is the most common psychiatric disorder of childhood and manifests as symptoms of developmentally inappropriate inattention, impulsivity and hyperactivity. Although numerous deficits have been identified in ADHD, one of the most consistent findings is …

A domain-general perspective on medial frontal brain activity during performance monitoring
Activity of the medial frontal cortex (MFC) has been implicated in attention regulation and performance monitoring. The MFC is thought to generate several event-related potential (ERPs) components, known as medial frontal negativities (MFNs), that are elicited when a behavioural response becomes …

Electrical Brain Activity and The Examinee's Level of Effort During Performance Validity Tasks
… are reported by individuals with mild Traumatic Brain Injuries. Limited studies have investigated how brain activity measured via Quantitative Electroencephalography (QEEG) relates to mental effort during cognitive tasks. The purpose of this study was to investigate electrical brain activity, as …

Functional Localization of Brain Activity in the Iowa Gambling Task Using Graph-Theoretical Methods
… Iowa Gambling Task (IGT). Several task-related brain regions have been found during IGT performance using standard subtraction-based neuroimaging paradigms. However, the identification of a proper baseline for the IGT has complicated the study of task-related activations in the IGT. In this …

Exploring the combined use of electrical and hemodynamic brain activity to investigate brain function
… between electrical and metabolic aspects of brain functioning in health and disease, measured with QEEG and NIRS, in order to evaluate its clinical potential. First the limitations of NIRS were investigated, depicting its susceptibility to different types of motion artefacts and the inability …

Time Course of Regional Brain Activity Associated With Top-Down Attentional Control in Depression
… source model to characterize the time course of activity in and relationships among specific brain regions, including LDLPFC (300-440 ms) and dACC (520-680 ms). dACC activity mediated the relationship between LDLPFC activity and Stroop interference (incongruent reaction time minus congruent …

Music on the Brain: Examining the Relationship Between Music Performance Anxiety, Mindfulness, and Brain Activity
… and behavioural effects in musicians with MPA. Brain regions related to attention and emotion regulation are thought to underly these findings. For example, in Study 1, a social-evaluative anxiety-provoking fMRI task was used to examine the neural activity and subjective anxiety levels …

Altered brain activity in autistic children versus healthy controls while performing simple tasks using fMRI
… matched controls, exhibit higher neuronal activity when identifying patterns or objects, but lower levels of activity in regards to facial recognition. The objective of this study was to examine both facial and object recognition and compare them to simple sensorimotor tasks. All subjects …

Differentiating Types of Anxiety, Depression, and Their Co-Occurrence: Regional Brain Activity and Life Stress
Distinct patterns of regional brain activity have been found to be characteristic of anxiety and depression in adults and late adolescents. However, there has been a substantial amount of inconsistency across studies as to the specific regions implicated. This electroencephalographic study …
