Cortical Networks Relating to Arousal Are Differentially Coupled to Neural Activity and Hemodynamics

Differences in Coupling Between Cortical Networks Related to Arousal in Neural Activity and Hemodynamics Academic Background In the absence of specific sensory inputs or behavioral tasks, the brain generates structured activity patterns. This organized activity is modulated by the state of arousal. The relationship between arousal and cortical acti...

Dopamine and Serotonin in Human Substantia Nigra Track Social Context and Value Signals During Economic Exchange

Dopamine and Serotonin in Human Substantia Nigra Track Social Context and Value Signals During Economic Exchange

Background Introduction In contemporary neuroscience research, dopamine and serotonin are hypothesized to be crucial neuromodulators guiding social behavior. However, there is a significant lack of understanding regarding the dynamic changes of these neuromodulators during social interactions. Although non-invasive functional neuroimaging methods (...

NMDA Receptor Autoantibodies Primarily Impair the Extrasynaptic Compartment

NMDA Receptor Autoantibodies Mainly Damage Extrasynaptic Components Background Information In recent years, neuroimmunology research has revealed various neurological and psychiatric diseases associated with autoantibodies. In these disorders, autoantibodies target various molecules, including receptor membrane proteins, causing abnormal neural sys...

GLP-1-directed NMDA Receptor Antagonism for Obesity Treatment

GLP-1-Directed NMDA Receptor Antagonism for Obesity Treatment In recent decades, obesity has become a global health problem, seriously affecting the quality of life and health of millions of people. Obesity is not only associated with numerous health issues such as diabetes, hypertension, and cardiovascular diseases but also severely impacts mental...

Fixel-Based Analysis Reveals Tau-Related White Matter Changes in Early Stages of Alzheimer’s Disease

Report: Revealing White Matter Changes Associated with Tau in Early Alzheimer’s Disease through Fixel-based Analysis Research Background Alzheimer’s Disease (AD) is generally thought to primarily affect the grey matter (GM), but more and more evidence shows that the white matter (WM) also experiences abnormalities. Current research largely relies o...

A 5' UTR Language Model for Decoding Untranslated Regions of mRNA and Function Predictions

A 5' UTR Language Model for Decoding Untranslated Regions of mRNA and Function Predictions

The 5’ untranslated region (5’UTR) is a regulatory region at the start of messenger RNA (mRNA) molecules, playing a crucial role in regulating the translation process and affecting protein expression levels. Language models have demonstrated effectiveness in decoding protein and genomic sequence functions. In this study, the authors introduce a lan...

Targeted Activation of Ferroptosis in Colorectal Cancer via LGR4 Targeting Overcomes Acquired Drug Resistance

Overcoming Acquired Resistance in Colorectal Cancer by Targeting LGR4 Research Background: Acquired drug resistance is a major obstacle in cancer treatment and a leading cause of cancer-related deaths. However, the mechanisms of resistance are diverse, and how to specifically target resistant cancer cells remains a significant clinical challenge. A...

Cognitive representations of intracranial self-stimulation of midbrain dopamine neurons depend on stimulation frequency

This paper reports a study on the cognitive representation of intracranial self-stimulation (ICSS) of midbrain dopamine neurons. The authors aimed to answer why rats work to obtain ICSS, i.e., how the pulsatile activation of dopamine neurons is represented in the brain. Research Background: The pulsatile activation of dopamine neurons is typically ...

Dimensionality reduction beyond neural subspaces with slice tensor component analysis

Background Introduction: Large-scale neural recording data can typically be described by patterns of co-activated neurons. However, the view of constraining neural activity variability to a fixed low-dimensional subspace may overlook higher-dimensional structures, such as fixed neural sequences or slowly evolving latent spaces. This study argues th...

Assessing the contribution of the chemical exposome to neurodegenerative disease

Assessing the contribution of the chemical exposome to neurodegenerative disease

Assessing the Risks of Chemical Exposures for Neurodegenerative Diseases Introduction In recent years, many environmental chemicals, from solvents to pesticides, have been implicated in the development and progression of neurodegenerative diseases. However, a systematic approach akin to genome-wide association studies, which have identified dozens ...
