By investigating auditory hyperexcitability in a mouse model for hereditary deafness, this study identified a subpopulation of afferent neurons of the auditory nerve marked by Otogl expression. Despite their apparently normal hearing, Otogl+/− mice display poor activation of afferent neurons processing loud sounds and an elevation of the middle the ear

Exploration of the functional consequences of fixational eye movements in the absence of a fovea. [PDF]
A recent theory posits that ocular drifts of fixational eye movements serve to reformat the visual input of natural images, so that the power of the input image is equalized across a range of spatial frequencies.

Visual and auditory attention in individuals with DYRK1A and SCN2A disruptive variants
Abstract This preliminary study sought to assess biomarkers of attention using electroencephalography (EEG) and eye tracking in two ultra‐rare monogenic populations associated with autism spectrum disorder (ASD). Relative to idiopathic ASD (n = 12) and neurotypical comparison (n = 49) groups, divergent attention profiles were observed for the monogenic

Pathology of the superior colliculus in chronic traumatic encephalopathy [PDF]
PURPOSE: To investigate neuropathological changes in the superior colliculus in chronic traumatic encephalopathy. METHODS: The densities of the tau-immunoreactive neurofibrillary tangles, neuropil threads, dot-like grains, astrocytic tangles, and ...

Visual Modulation of Acoustic Reflex Measurements: Insights Into Sensory Integration
Visual tasks have a measurable effect on acoustic reflex thresholds and latencies, likely due to cross‐modal interactions between the auditory and visual systems. ABSTRACT Objective The aim was to investigate the impact of visual tasks on acoustic reflex thresholds (ARTs) and AR latencies (ARLs) during AR measurements.

Abstract Aim Because of their stable expression, some EF‐hand Ca2+‐binding proteins are broadly used as histochemical markers of neurons in the nervous system. Secretagogin is a member of “neuron‐specific” Ca2+‐sensor proteins, yet variations in its expression due, chiefly, to neuronal activity remain ambiguous.

The role of GABA-B in sensorigating processing disorders in rat models, an autoradiographic study [PDF]
INTRODUCTION: The process of sensorimotor gating is a neurological phenomenon referring to the brain’s ability to process and filter out stimuli in order to prevent an overflow of information.

Opioid modulation of GABA release in the rat inferior colliculus [PDF]
Background: The inferior colliculus, which receives almost all ascending and descending auditory signals, plays a crucial role in the processing of auditory information.

Neural Dynamics of Saccadic and Smooth Pursuit Eye Movement Coordination during Visual Tracking of Unpredictably Moving Targets [PDF]
How does the brain use eye movements to track objects that move in unpredictable directions and speeds? Saccadic eye movements rapidly foveate peripheral visual or auditory targets and smooth pursuit eye movements keep the fovea pointed toward an ...

Target Selection by Frontal Cortex During Coordinated Saccadic and Smooth Pursuit Eye Movement [PDF]
Oculomotor tracking of moving objects is an important component of visually based cognition and planning. Such tracking is achieved by a combination of saccades and smooth pursuit eye movements.
