Mini G Protein Inhibits Internalization of Same GPCR and Disrupts Downstream Intracellular Signaling Introduction G protein-coupled receptors (GPCRs) are the largest class of transmembrane proteins, regulating cellular responses to external stimuli such as hormones and neurotransmitters. GPCRs transmit signals by coupling with guanine nucleotide-bi...
Research Report on Multi-sensory Flicker Regulating Extensive Brain Networks and Reducing Interictal Epileptiform Discharges Background Introduction In treating neurological disorders, modulating brain oscillations has great potential. Non-invasive interventions, suitable for everyday use at home, have become the focus of the scientific community, ...
Deep Learning Model Reveals Mechanisms of Semantic Satiation Semantic satiation, the phenomenon where a word or phrase loses its meaning after being repeated many times, is a well-known psychological phenomenon. However, the micro-neural computational principles underlying this mechanism remain unknown. This paper uses a continuous coupled neural n...
Electrophysiological Signatures of Veridical Head Direction in Humans Navigation is one of the core components of human complex cognition, where head direction information is crucial for positioning oneself in space. However, due to the requirement of having the head fixed in a specific position during most neuroimaging experiments, understanding h...
The Ventral Subiculum Promotes Wakefulness Through Multiple Pathways in Male Mice Background The ventral subiculum (vsub) is a major output region of the hippocampus, playing a crucial role in motivation, stress integration, and anxiety-like behavior, all of which depend on a high state of wakefulness. However, the role of vsub in wakefulness and i...
Study on the Differences in Cortical Layers During Epileptic Seizure Onset and Spread Epilepsy is a neurological disorder that severely impacts patients’ quality of life, affecting approximately 1% of the global population. Among all epilepsy patients, nearly one-third are resistant to pharmaceutical treatments, known as drug-resistant epilepsy. Fo...
Topographical Map of the 1/f Index in the Whole Brain for Parkinson’s Disease Authors: Pascal Helson, Daniel Lundqvist, Per Svenningsson, Mikkel C. Vinding, Arvind Kumar Research Background Parkinson’s Disease (PD) is a progressive and debilitating brain disorder primarily characterized by motor dysfunction but also affecting perceptual and cogniti...
Modulation of P3m Amplitude by Task Difficulty in a Visual Oddball Task Background In cognitive neuroscience research, Event-Related Potentials (ERP) and Event-Related Fields (ERF) are important means to explore the cognitive processing mechanisms of the brain. Among these, the P3 component (referred to as P3m in magnetoencephalography) has garnere...
Neurophysiological Study: Neurophysiological Research on Orientation Discrimination in a Working Memory Task Background Recognizing and remembering the spatial orientation of the environment is a crucial component of visuospatial behavior. Accurately storing and recalling this information helps us navigate in space and respond adaptively to rapid c...
Study on Theta Oscillations in Hippocampus-Prefrontal Interaction Supporting Sequential Working Memory Academic Background The dorsolateral prefrontal cortex (DLPFC) and the hippocampus play crucial roles in sequential working memory, but the specific interaction mechanisms are not yet clear. Previous studies have shown that these two brain regions...
