Limiting sugar before the age of two is linked to a lower risk of dementia later in life, research suggests. A study based on almost 65,000 people from the UK found that sugar rationing may be linked ...
IntroductionKinesthetic illusion (KI) induced by tendon vibration (VIB) is known for activation in sensorimotor areas and antagonist vibratory response (AVR) of the antagonist muscle. We hypothesize that coupling between…
Despite the growing role of neurotechnologies in neuroscience and clinical care, Black African communities remain critically underrepresented in the UK research and clinical trials. Historical lack of diversity in…
IntroductionIntrinsic EEG oscillations provide a non-invasive window into arousal- and attention-related individual differences, but resting low-frequency EEG correlates of adult attention-deficit/hyperactivity disorder…
Music-based interventions are gaining traction in therapeutic settings, yet evidence remains centered on Western music and populations. This gap is particularly important for Middle Eastern populations, where the Maqam…
BackgroundMajor depressive disorder (MDD) is a leading cause of disability; however, its neurogenetic mechanisms remain partially understood. Comparative genomic approaches reveal evolutionarily conserved risk factors…
BackgroundClinical decision-making often occurs under conditions of high cognitive load, emotional stress, and time pressure. Psychological distancing, an emotion-focused coping strategy involving the mental separation…
The red blood cell distribution width-to-albumin ratio (RAR) is an index reflecting inflammatory and nutritional status. While prior studies reported cross-sectional associations between RAR and cognitive performance…
Alternative splicing is a fundamental mechanism underlying protein diversity. The microtubule-associated protein tau (MAPT) undergoes age-associated alternative splicing of exon 10 to generate 3 R and 4 R isoforms, and…
Emerging neuroimaging evidence shows that pathological tau proteins build up along specific brain networks, suggesting that large-scale network architecture plays a key role in the progression of Alzheimerâs disease…
Early diagnosis of Parkinsonâs disease (PD) is critical, as clinical symptoms typically emerge only after substantial neuronal loss. While α-synuclein (α-Syn) oligomers in blood are promising biomarkers for early…
Previous studies have demonstrated widespread regional abnormalities in blood oxygen level-dependent (BOLD) amplitude of low frequency fluctuation (ALFF) in psychotic disorders. How regional ALFF is related to functional…
Isolated REM sleep behavior disorder is a high-risk prodromal syndrome for Lewy body diseases but highly heterogeneous. Neurophysiologic markers resolving this heterogeneity and predicting phenoconversion remain limited…
Olfactory decline is an early sign of Parkinsonâs disease (PD), often preceding motor symptoms by years to decades. However, because olfactory impairment is also common in healthy and diseased aging, current olfactory…
A recent publication [1] in this journal reported findings from the use of the tracer [11C]K-2 for PET imaging of brain AMPA receptors in patients with major psychiatric disorders. [11C]K-2 functions by a pro-drug-like…
Ants and bees are known to use spatial memories to navigate to fixed locations, such as a nest. Virtual-reality experiments in which Drosophila fruit flies follow fictive odour plumes now show that these insects use…
Thalamic deep brain stimulation (DBS) is an established neuromodulatory treatment option for drug-resistant epilepsy (DRE), but presurgical markers associated with the postoperative response remain incompletely…
Feeding is tightly regulated by hypothalamic circuits that integrate circadian and metabolic cues, yet the neuromodulatory systems coordinating these signals remain incompletely understood. Cholinergic neurons within the…
V2a interneurons are excitatory neurons found throughout the hindbrain and spinal cord, two regions that arise from distinct progenitors during embryonic development. Whether this lineage difference shapes mature gene…
Na+,K+-ATPases establish and maintain the vital electrochemical gradients for Na+ and K+ across animal cell membranes. The protein is a ternary complex composed of α, β and FXYD subunits, of which isoforms that fine-tune…
Intestinal circadian clocks are emerging as important regulators of gastrointestinal physiology and homeostasis. Recent advances suggest that desynchronization of circadian clocks in distinct intestinal cell types could…
Traditional models of brain connectivity primarily focus on pairwise interactions, overlooking collective dynamics among multiple regions. Although many higher-order interaction (HOI) metrics have been proposed, their…
Dysfunctional mitophagy is proposed as a key component of Alzheimerâs disease (AD) pathology, yet direct in vivo evidence and mechanistic insights are still lacking. Here we show that AD model mice expressing a…
The entorhinal–hippocampal circuit plays a central role in episodic memory, yet the contribution of the medial entorhinal cortex (MEC) ultraslow (< 0.01 Hz) oscillation remains poorly understood. Here, we develop a…
Dietary nicotinamide (NAM) is neuroprotective in rodent models of glaucoma. With dietary delivery, additional systemic influences of NAM are possible, prompting us to test for influences on non-neuronal phenotypes…
Hearing loss is a major modifiable risk factor for Alzheimerâs disease (AD), but how auditory deprivation engages specific neural circuits, particularly in a sex-dependent manner, to promote amyloid pathology remains…
Microglia, the brainâs resident immune cells, are increasingly recognized as key regulators of brain physiology and behavior. However, their specific role in affective states remains controversial, with studies…
Low-dimensional manifolds underlie mental and cognitive representations, and characterizing individual differences is critical to neuropsychiatric research. Existing manifold learning methods either distort…
Memory formation relies on the reorganization of neural activity patterns during experience that persist in subsequent sleep. How these processes promote learning while preserving established memories remains unclear…
Several modifiable risk factors for dementias have been identified including socio-economic status and environmental exposures â however, how these population-level risks relate to individual risk remains elusive. To…
