Introduction: Traumatic brain injury can impair the central auditory pathways and auditory cortex. Hence, individuals who suffered a traumatic brain injury may be at risk of central auditory processing disorders, which can be identified with behavioral tests that assess central auditory function.
Objective: To characterize and compare the performance of children and adolescents with and without a history of traumatic brain injury in behavioral tests that assess central auditory processing.
Method: The sample comprised 8- to 18-year-old individuals of both sexes who suffered moderate or severe closed traumatic brain injury 3 to 24 months before their participation in the study and whose hearing thresholds were normal. These individuals were matched for sex and age with other subjects without a history of traumatic brain injury and submitted to behavioral assessment of the central auditory processing with special tests to assess hearing skills (namely, auditory closure, figure-ground, and temporal processing), selected according to their chronological age and response-ability.
Results: The study group performed statistically worse than the comparison group in auditory closure, figure-ground in verbal dichotic listening, and temporal ordering. The central auditory processing tests with abnormal results in the comparison group were different from those in the study group.
Conclusion: Central auditory processing disorders were identified in all subjects of the study group, especially involving auditory closure and temporal processing skills, in comparison with subjects without a history of traumatic brain injury.

Aberrant controllability of functional connectome during working memory tasks in patients with schizophrenia and unaffected siblings.
Br J Psychiatry
January 2025
Douglas Mental Health University Institute, Department of Psychiatry, McGill University, Montreal, Canada.
Background: Working memory deficit, a key feature of schizophrenia, is a heritable trait shared with unaffected siblings. It can be attributed to dysregulation in transitions from one brain state to another.
Aims: Using network control theory, we evaluate if defective brain state transitions underlie working memory deficits in schizophrenia.
Clinical severity grading of NF2-related schwannomatosis.
Orphanet J Rare Dis

Department of Neurosurgery, Helios Klinikum Erfurt, Erfurt, Germany.
Background: NF2-related schwannomatosis (NF2) is associated with various tumors of the central and peripheral nervous system. There is a wide range of disabilities these patients may suffer from and there is no validated clinical classification for disease severity. We propose a clinical classification consisting of three severity grades to assist in patient management.

Biosciences Institute, Newcastle University, Newcastle upon Tyne, UK.
The story of David Ferrier's demonstration at the International Medical Congress in London in August 1881 of a monkey experimentally rendered hemiplegic by a focal surgical brain lesion-prompting Charcot's observation, "C'est un malade!"-is well known as a seminal event in the history of the localization of functions in the cerebral cortex. Less well known is the fact that, on the same occasion, Ferrier demonstrated a second monkey, known as monkey F, apparently deaf as a consequence of bilateral temporo-sphenoidal brain lesions. The purpose of this article is, first, to give a chronological account of this demonstration and subsequent related events, including Ferrier's trial under the Vivisection Act, the publication of the pathological findings in the animal's brain, the dispute about the localization of the "auditory centre" with Edward Schäfer, and the first glimmerings of human homologues of cortical deafness.
View Article and Find Full Text PDFAge-related hearing loss (ARHL) is considered one of the most common neurodegenerative disorders in the elderly; however, how it contributes to cognitive decline is poorly understood. With resting-state functional magnetic resonance imaging from 66 individuals with ARHL and 54 healthy controls, group spatial independent component analyses, sliding window analyses, graph-theory methods, multilayer networks, and correlation analyses were used to identify ARHL-induced disturbances in static and dynamic functional network connectivity (sFNC/dFNC), alterations in global network switching and their links to cognitive performances. ARHL was associated with decreased sFNC/dFNC within the default mode network (DMN) and increased sFNC/dFNC between the DMN and central executive, salience (SN), and visual networks.

The round goby (Neogobius melanostomus) is a benthic fish species native to Central Eurasia but has colonized much of the waterways in the Laurentian Great Lakes in North America. While they are known to produce acoustic signals that aid in conspecific agonistic and reproductive interactions, the species does not possess a swim bladder and thus does not have any hearing specializations that would allow for sound pressure detection. Here, the auditory evoked potentials from saccular hair cells were characterized to determine the frequency response and auditory sensitivity of the saccule.
