Neural correlates of multisensory enhancement in audiovisual narrative speech perception: A fMRI investigation

This fMRI study investigated the effect of seeing articulatory movements of a speaker while listening to a naturalistic narrative stimulus. It had the goal to identify regions of the language network showing multisensory enhancement under synchronous …

Attentional influences on neural processing of biological motion in typically developing children and those on the autism spectrum

Biological motion imparts rich information related to the movement, actions, intentions and affective state of others, which can provide foundational support for various aspects of social cognition and behavior. Given that atypical social …

Neurophysiological correlates of dual tasking in people with Parkinson's disease and freezing of gait.

Freezing of gait in people with Parkinson's disease (PwP) is associated with executive dysfunction and motor preparation deficits. We have recently shown that electrophysiological markers of motor preparation, rather than decision-making, …

FEELING OURSELVES MOVE: A TEAM EFFORT BY OUR SENSES

As you walk, bike, or drive down the street, your brain puts together (integrates) sensory information from different sources. It uses what you see, what you hear, and how your head and body move to help you judge your own movements. As you move, …

Current source density approaches improve spatial resolution in event related potential analysis in people with Parkinson's disease.

A letter discussing the use of Current Source Density to analyse EEG data for people with Parkinson's Disease

Cognitive load reduces the effects of optic flow on gait and electrocortical dynamics during treadmill walking

During navigation of complex environments, the brain must continuously adapt to both external demands, such as fluctuating sensory inputs, and internal demands, such as engagement in a cognitively demanding task. Previous studies have demonstrated …

Visual–Vestibular Integration During Self-Motion Perception in Younger and Older Adults

Younger adults integrate visual and vestibular cues to self-motion in a manner consistent with optimal integration; however, little is currently known about whether this process changes with older age. Our objective was to determine whether older …

Long-term test-retest reliability of event-related potential (ERP) recordings during treadmill walking using the mobile brain/body imaging (MoBI) approach

Advancements in acquisition technology and signal-processing techniques have spurred numerous recent investi- gations on the electro-cortical signals generated during whole-body motion. This approach, termed Mobile Brain/ Body Imaging (MoBI), has the …

Motor Preparation Rather Than Decision-Making Differentiates Parkinson's Disease Patients With And Without Freezing of Gait

Objective: Freezing of gait (FOG) is a brief, episodic phenomenon affecting over half of people with Parkinson’s disease (PD) and leads to significant morbidity. The pathophysiology of FOG remains poorly understood but is associated with deficits in …

An Examination of the Neural Unreliability Thesis of Autism

An emerging neuropathological theory of Autism, referred to here as the neural unreliability thesis, proposes greater varability in moment-to-moment cortical representation of environmental events, such that the system shows general instability in …
