Article Synopsis
  • Visceral leishmaniasis (VL) is a neglected tropical disease largely affecting regions like Brazil, East Africa, and India, where atypical presentations, such as neurological symptoms, complicate diagnosis due to their rarity.
  • A clinical case involving a 38-year-old man showcased how VL can present with uncommon signs like back pain, tingling, and double vision, leading to an initial misdiagnosis of other conditions, but ultimately confirmed as VL through various tests, including CSF analysis and qPCR.
  • The patient's successful treatment with liposomal amphotericin B and miltefosine emphasizes the importance of recognizing atypical manifestations of VL in endemic areas to ensure timely and effective management.

Understanding the function of sleep and its associated neural rhythms is an important goal in neuroscience. While many theoretical models of neural dynamics during sleep exist, few include the effects of neuromodulators on sleep oscillations and describe transitions between sleep and wake states or different sleep stages. Here, we started with a C++-based thalamocortical network model that describes characteristic thalamic and cortical oscillations specific to sleep.

Article Synopsis
  • * A new method was developed that combines MEG with electromyography (EMG) to accurately locate early-stage motor cortex activity during self-paced finger movements without averaging multiple trials over a minute-long recording.
  • * The study found that this EMG-projected MEG technique effectively identified motor cortex activity in both healthy participants and presurgical patients, even when muscle movements were irregular, shedding light on how the brain communicates with muscles during various frequency bands.

Unlabelled: The global increase in the aging population has raised concerns over various age-related conditions like dementia and mild cognitive impairment (MCI) and their consequences on the affected persons. People with MCI exhibit cognitive deficits more significantly than expected for their age and literacy level. Though the nature of this condition is considered "mild", studies have reported that even more subtle deficits can influence the quality of life (QOL).

Article Synopsis
  • * These poly-GR proteins disrupt general protein synthesis by interfering with the translation process, particularly slowing down the translation of certain transcripts.
  • * The resulting stress from stalled translation causes ribosome collisions and triggers a harmful ribotoxic stress response, but inhibiting specific pathways can reduce toxicity and improve neuron survival in affected patients.

A scalable platform to synthesize ultrathin heavy metals may enable high-efficiency charge-to-spin conversion for next-generation spintronics. Here, we report the synthesis of air-stable, epitaxially registered monolayer Pb underneath graphene on SiC (0001) by confinement heteroepitaxy (CHet). Diffraction, spectroscopy, and microscopy reveal that CHet-based Pb intercalation predominantly exhibits a mottled hexagonal superstructure due to an ordered network of Frenkel-Kontorova-like domain walls.

Background: Current standard management in adult grades 2-4 gliomas includes maximal safe resection followed by adjuvant radiotherapy (RT) and chemotherapy. Radiation-induced lymphopenia (RIL) has been shown to possibly affect treatment outcomes adversely. Proton beam therapy (PBT) may reduce the volume of the normal brain receiving moderate radiation doses, and consequently RIL.

Slow-wave sleep (SWS), characterized by slow oscillations (SOs, <1Hz) of alternating active and silent states in the thalamocortical network, is a primary brain state during Non-Rapid Eye Movement (NREM) sleep. In the last two decades, the traditional view of SWS as a global and uniform whole-brain state has been challenged by a growing body of evidence indicating that SO can be local and can coexist with wake-like activity. However, the mechanisms by which global and local SOs arise from micro-scale neuronal dynamics and network connectivity remain poorly understood.

GGGGCC (GC) repeat expansion in C9ORF72 is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). How this genetic mutation leads to neurodegeneration remains largely unknown. Using CRISPR-Cas9 technology, we deleted EXOC2, which encodes an essential exocyst subunit, in induced pluripotent stem cells (iPSCs) derived from C9ORF72-ALS/FTD patients.

There have been many published picture corpora. However, more than half of the world's population speaks more than one language and, as language and culture are intertwined, some of the items from a picture corpus designed for a given language in a particular culture may not fit another culture (with the same or different language). There is also an awareness that language research can gain from the study of bi-/multilingual individuals who are immersed in multilingual contexts that foster inter-language interactions.

Brain activity during the resting state is widely used to examine brain organization, cognition and alterations in disease states. While it is known that neuromodulation and the state of alertness impact resting-state activity, neural mechanisms behind such modulation of resting-state activity are unknown. In this work, we used a computational model to demonstrate that change in excitability and recurrent connections, due to cholinergic modulation, impacts resting-state activity.
