Effect of HRTFs and head motion on auditory-visual localization in real and virtual studio environments

Acta Acustica
When localizing sound sources in natural or virtual environments, multisensory integration that combines auditory and visual cues is often involved. This study aims to determine the effect of (non-)individual head-related transfer functions (HRTFs) on ...

Quantitative MRI Uncovers Subtle Cortical Damage in Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether myelin‐sensitive quantitative MRI reveals microstructural abnormalities in normal‐appearing cortex (NACtx) in myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), indicating that conventional MRI underestimates remission residual cortical injury.

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Modeling Progressive Brain Volume Losses in Chronic Moderate Severe Traumatic Brain Injury: Extensive, but Attenuating

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Progressive brain atrophy has now been widely observed in the chronic stages of moderate–severe traumatic brain injury (msTBI), but there is only coarse information regarding its prevalence and magnitude, and whether rate of atrophy accelerates or attenuates across time. We examined these questions in a Canadian inception cohort from

Minimal positive realizations of transfer functions with nonnegative multiple poles [PDF]

, 2005
This note concerns a particular case of the minimality problem in positive system theory. A standard result in linear system theory states that any nth-order rational transfer function of a discrete time-invariant linear single-input-single-output (SISO)

Measurement of head-related transfer functions based on the empirical transfer function estimate

, 2003
An experimental procedure and signal processing method to mea-sure Head Related Transfer Functions (HRTFs) is reviewed. The technique based on Fourier analysis system identification has an advantage over the commonly used maximum-length sequence and ...

Modeling of Individual Head-Related Transfer Functions (HRTFs) Based on Spatiotemporal and Anthropometric Features Using Deep Neural Networks

IEEE Access
This paper presents an innovative approach for personalized modeling of Head-Related Transfer Functions (HRTFs) using deep neural networks (DNNs), with a primary focus on addressing interaural time differences (ITDs), torso and pinna anthropometrics ...
