In an exhaustive exploration fit for a Sunday morning pot of Earl Grey, researchers have delineated the genetic outlines of 14 psychiatric disorders. This bone-dry epic on genetic variance pinpoints a handful of factors that might explain the inscrutable tangle of our mental maladies.
Channeling a touch of Hercule Poirot's precision, researchers have discovered that a single gene, GRIN2A, might be the elusive culprit responsible for causing mental illness previously attributed to a cocktail of genetic mischief-makers. A tale worth every light flicker in your laboratory.
This activity discusses the assessment of suicide risk in clinical settings, offering CME credits for participants. It is supported by AKH Inc., Advancing Knowledge in Healthcare.
This work presents a fully implantable wireless optogenetic device that delivers spatiotemporally patterned cortical stimulation through the skull and generates artificial perception in mice.
A new analysis shows that anti-inflammatory medications may help reduce symptoms for a subset of people with depression who also have chronic, low-grade inflammation. By reviewing randomized controlled trials that specifically enrolled individuals with elevated inflammatory markers, researchers found that anti-inflammatory treatments significantly reduced both overall depressive symptoms and anhedonia.
A new study using advanced deep-learning brain age estimation shows that World Trade Center responders with PTSD exhibit signs of accelerated brain aging. Using BrainAgeNeXt, a model trained on more than 11,000 MRI scans, researchers found that responders with PTSD had “older” appearing brains than those without the disorder, especially among individuals with longer exposure at Ground Zero.
This activity is part of a case study series focusing on PTSD among veterans, supported by educational grants from Otsuka America Pharmaceutical, Inc., and Lundbeck.
This research examines how transcranial magnetic stimulation (TMS) can modulate neural circuits related to suicidal ideation and behavior, proposing TMS as a potential therapeutic alternative to mitigate suicide risk in at-risk populations.
Epitranscriptomic (m6A) profiling across five human brain regions and developmental stages uncovers region-specific and age-specific dynamics, preferential enrichment in disease-associated genes, and colocalization with disease risk loci.
Using multineuron patch clamp in human cortex, the authors uncover four functional subtypes of pyramidal neurons with distinct morphology and subtype-specific synaptic interactions, revealing conserved microcircuit principles among individuals.
This study explores the relationship between altered cortical gyrification and treatment resistance in patients experiencing their first episode of psychosis. The findings suggest that specific patterns of gyrification may serve as biomarkers for treatment outcomes in this patient population.
The article demonstrates a novel algorithm for tracking neurons over early postnatal development, highlighting transitions in neural firing patterns.
New research shows that deep learning can use EEG signals to distinguish Alzheimer’s disease from frontotemporal dementia with high accuracy. By analyzing both the timing and frequency of brain activity, the model uncovered distinct patterns: broader disruption across multiple regions in Alzheimer’s and more localized frontal and temporal changes in frontotemporal dementia.
This article discusses the effects of corticosterone on behavioral inflexibility and its relation to gene expression involved in neuroplasticity.
An intestinal organoid model recapitulates human microfold (M) cell function and transcriptomic profiling and biochemical assays demonstrate that M cells uptake and present antigens to the immune system via the class II major histocompatibility complex.
This research article discusses the mechanisms behind state-dependent filtering and its implications for visual robustness.
