A receptor-based analysis of local ecosystems in the human brain. [PDF]

, 2017
BackgroundAs a complex system, the brain is a self-organizing entity that depends on local interactions among cells. Its regions (anatomically defined nuclei and areas) can be conceptualized as cellular ecosystems, but the similarity of their functional ...

Hearing Function in Spinal and Bulbar Muscular Atrophy (SBMA): A Case Control Study From a Tertiary Referral Center

European Journal of Neurology, Volume 32, Issue 6, June 2025.
ABSTRACT Background Expanding on earlier findings of auditory involvement from two small‐scale studies, we conducted a comprehensive evaluation of hearing levels in a larger cohort of SBMA patients. Methods Thirty‐six SBMA patients and 36 age‐matched male controls without risk factors for hearing loss underwent a comprehensive audiological assessment ...

NMDA Currents Modulate the Synaptic Input–Output Functions of Neurons in the Dorsal Nucleus of the Lateral Lemniscus in Mongolian Gerbils [PDF]

, 2011
Neurons in the dorsal nucleus of the lateral lemniscus (DNLL) receive excitatory and inhibitory inputs from the superior olivary complex (SOC) and convey GABAergic inhibition to the contralateral DNLL and the inferior colliculi.

Time‐restricted feeding mitigates Alzheimer's disease‐associated cognitive impairments via a B. pseudolongum‐propionic acid‐FFAR3 axis

iMeta, Volume 4, Issue 2, April 2025.
A 4‐month of time‐restricted feeding (TRF) intervention alleviated cognitive impairments in Alzheimer's disease (AD) patients, while a 3‐month TRF regimen improved spatial memory, reduced amyloid‐beta accumulation, and promoted microglial aggregation around plaques in AD mice. Antibiotic‐induced gut microbiota depletion partly abolished TRF's benefits.

Measurement of Anteroposterior diameters of normal brainstem by Magnetic Resonance Imaging

Journal of Gandaki Medical College, 2019
Aim: The aim of this study is to assess the anteroposterior diameter of brainstem (midbrain, pons and medulla) of normal Nepalese people to establish normal ranges and to correlate the measurement with pa­tient’s age and gender. Method: The study is a

Central Involvement in Pure Autonomic Failure: Insights from Neuromelanin‐Sensitive Magnetic Resonance Imaging and 18F‐Fluorodopa‐Positron Emission Tomography

Movement Disorders, Volume 40, Issue 4, Page 716-726, April 2025.
Abstract Background Central synucleinopathies, including Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), involve alpha‐synuclein accumulation and dopaminergic cell loss in the substantia nigra (SN) and locus coeruleus (LC).

One hundred ways to process time, frequency, rate and scale in the central auditory system: a pattern-recognition meta-analysis

Frontiers in Computational Neuroscience, 2015
The mammalian auditory system extracts features from the acoustic environment based on the responses of spatially distributed sets of neurons in the subcortical and cortical auditory structures.

Decreasing predictability of visual motion enhances feed-forward processing in visual cortex when stimuli are behaviorally relevant [PDF]

, 2016
Recent views of information processing in the (human) brain emphasize the hierarchical structure of the central nervous system, which is assumed to form the basis of a functional hierarchy.
