Probable vestibular paroxysmia mimicking benign paroxysmal positional vertigo of the superior semicircular canal in the presence of a neurovascular conflict: a case report and review of the literature

Positional vertigo is a frequent complaint in otology and vestibular physiotherapy, arising from functional or structural causes affecting the peripheral or central vestibular systems. Although benign paroxysmal positional vertigo (BPPV) is the most common form, other etiologies...

Neurofeedback enhances a neural signature of selective attention to speech in cocktail-party settings

Understanding speech in noisy situations is challenging and often fails due to attentional rather than sensory deficits. We report here that neurofeedback can enhance a neural signature of selective attention to speech in a cocktail-party setting. Neural responses to speech were...

Emotional Responses (Intensity/Valence) Fulfill RDoC Criteria but Remain Excluded From Diagnostic Classifications of Mood Disorders

OBJECTIVES: Categorical classifications of depression, such as DSM-5 and ICD, are limited by high clinical heterogeneity, arbitrary diagnostic thresholds, and weak links to underlying pathophysiology. In line with the Research Domain Criteria (RDoC) framework, this article propos...

Diagnostic Performance of Vestibular‐Evoked Myogenic Potentials for Acute Unilateral Vestibulopathy: A Systematic Review and Meta‐analysis

Abstract Objective The goal of this study is to evaluate the pooled diagnostic performance of cervical (cVEMP) and ocular (oVEMP) vestibular‐evoked myogenic potentials for Acute Unilateral Vestibulopathy. Data Sources MEDLINE, EMBASE, Scopus, and Cochrane Central were searched fo...

AI Consciousness and Existential Risk

In AI, existential risk denotes the hypothetical threat posed by an artificial system that would possess both the capability and the objective, either directly or indirectly, to eradicate humanity. This issue is gaining prominence in scientific debate due to recent technical adva...

Oscillatory Traveling Waves During Visual Entrainment in Autistic and Non-Autistic Adults

Neural oscillations and traveling waves play a crucial role in cognition. In scalp electroencephalography (EEG), waves typically travel along the anterior-posterior axis: forward waves (occipital-to-frontal) predominate during sensory stimulation, while backward waves (frontal-to...

Thalamocortical network dynamics can explain visual impulse responses and perceptual echoes

Although temporal information is ubiquitous in natural vision, the cortex shows strong intrinsic rhythmicity. Recent electroencephalogram (EEG) studies have revealed a component of the visual impulse response function (IRF) resembling a narrow alpha-band (7–13 Hz) filter with a s...
