Amygdala Neurodegeneration: A Key Driver of Visual Dysfunction in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Visual disability in Parkinson's disease (PD) is not fully explained by retinal neurodegeneration. We aimed to delineate the brain substrate of visual dysfunction in PD and its association with retinal thickness. Methods Forty‐two PD patients and 29 controls underwent 3‐Tesla MRI, retinal spectral‐domain optical coherence tomography,

Perception of biological motion from size-invariant body representations

Frontiers in Integrative Neuroscience, 2015
The visual recognition of action is one of the socially most important and computationally demanding capacities of the human visual system. It combines visual shape recognition with complex non-rigid motion perception.

Subjective Size Perception Depends on Central Visual Cortical Magnification in Human V1

PLoS ONE, 2013
In the Ebbinghaus illusion, the context surrounding an object modulates its subjectively perceived size. Previous work implicates human primary visual cortex (V1) as the neural substrate mediating this contextual effect.

Roles of Scaling and Instruction Tuning in Language Perception: Model vs. Human Attention [PDF]

arXiv, 2023
Recent large language models (LLMs) have revealed strong abilities to understand natural language. Since most of them share the same basic structure, i.e. the transformer block, possible contributors to their success in the training process are scaling and instruction tuning. However, how these factors affect the models' language perception is unclear.

Phonemes and Syllables in Speech Perception: size of the attentional focus in French. [PDF]

, 1997
A study by Pitt and Samuel (1990) found that English speakers could narrowly focus attention onto a precise phonemic position inside spoken words [1]. This led the authors to argue that the phoneme, rather than the syllable, is the primary unit of speech

Combination Therapy With Vigabatrin and Prednisolone Versus Vigabatrin Alone for Infantile Spasms

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The study evaluated the effectiveness of combination therapy with vigabatrin and prednisolone versus vigabatrin alone for treating infantile epileptic spasms syndrome (IESS). Methods This single‐center, single‐blind, randomized trial enrolled infants aged 2–14 months with new‐onset IESS, randomly assigned them (1:1) to receive either

Illusion Spaces in VR: The Interplay Between Size and Taper Angle Perception in Grasping [PDF]

Leveraging the integration of visual and proprioceptive cues, research has uncovered various perception thresholds in VR that can be exploited to support haptic feedback for grasping. While previous studies have explored individual dimensions, such as size, the combined effect of multiple geometric properties on perceptual illusions remains poorly ...

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.

VIP interneurons regulate cortical size tuning and visual perception

Cell Reports, 2023
Summary: Cortical circuit function is regulated by extensively interconnected, diverse populations of GABAergic interneurons that may play key roles in shaping circuit operation according to behavioral context.
