Active Vision in Freely Moving Marmosets Using Head-Mounted Eye Tracking

Study of Visual Behavior in Freely Moving Primates: Development and Application of an Innovative Eye-Tracking System Academic Background The visual system is one of the most extensively studied areas within the primate nervous system, particularly concerning the mechanisms of visual pathways in the cerebral cortex. However, current research on how ...

Evidence for Domain-General Arousal from Semantic and Neuroimaging Meta-Analyses Reconciles Opposing Views on Arousal

Neuroscientific Research Report on “Domain-General Arousal” Academic Background Arousal is a core concept in neuroscience, referring to fluctuations in brain and body states that underpin motivated behavior. Despite the widespread use of the term “arousal,” its definition has remained ambiguous, with differing interpretations in various textbooks. ...

Fixational Eye Movements as Active Sensation for High Visual Acuity

Fixational Eye Movements as Active Sensation for High Visual Acuity Academic Background Human visual perception is a complex process, especially when we attempt to maintain stable gaze. Even then, the eyes still produce small involuntary movements known as fixational eye movements (FEM). These FEM typically include drifts and microsaccades. Previou...

Intracranial Substrates of Meditation-Induced Neuromodulation in the Amygdala and Hippocampus

Study on the Neuroregulatory Effects of Meditation: A Case Study of Loving-Kindness Meditation Academic Background Meditation, as a mental training technique, has long been believed to regulate emotions and enhance mental health. Specifically, Loving-Kindness Meditation (LKM), which focuses on cultivating positive emotions towards oneself and other...

The Role of Electroencephalography in Epilepsy Research—From Seizures to Interictal Activity and Comorbidities

The Role of Electroencephalography in Epilepsy Research: From Seizures to Interictal Activity and Comorbidities Academic Background Since the early 20th century, electroencephalography (EEG) has been a key tool in epilepsy research. EEG technology not only helps scientists record and analyze brain signals but also reveals the pathophysiological mec...

Neurocritical Care Organization in Low-Income and Middle-Income Countries

Neurocritical Care Organization in Low- and Middle-Income Countries Academic Background and Problem Statement Neurocritical care (NCC) has rapidly evolved over the past few decades as a distinct subspecialty of critical care medicine. Evidence shows that patients with acute brain injuries have significantly improved outcomes when treated in dedicat...

Serum NfL and Neuropsychological Performance over ∼8 Years in Women with and without HIV: A Longitudinal Repeated Measures Study

Serum Neurofilament Light Chain and Cognitive Performance in Women with and without HIV: A Longitudinal Study Over Approximately 8 Years Research Background With the widespread use of highly active antiretroviral therapy (ART), the life expectancy of individuals infected with human immunodeficiency virus (HIV) has significantly increased. However, ...

Homeostasis and Metabolism of Iron and Other Metal Ions in Neurodegenerative Diseases

Homeostasis and Metabolism of Iron and Other Metal Ions in Neurodegenerative Diseases Academic Background Neurodegenerative diseases (such as Parkinson’s disease, Alzheimer’s disease, amyotrophic lateral sclerosis, and Huntington’s disease) are characterized by neuronal death and gradual loss of function, leading to the deterioration of cognitive, ...

Causal Associations Between Sleep Traits, Sleep Disorders, and Glioblastoma: A Two-Sample Bidirectional Mendelian Randomization Study

Causal Associations Between Sleep Traits, Sleep Disorders, and Glioblastoma: A Two-Sample Bidirectional Mendelian Randomization Study Academic Background Introduction Glioblastoma (GBM) is the most aggressive and common type of malignant brain tumor, accounting for nearly 50% of all primary brain tumors in adults. It primarily originates from astro...

The Calcium Channel Blocker Nimodipine Inhibits Spinal Reflex Pathways in Humans

The Effect of Calcium Channel Blocker Nimodipine on Human Spinal Reflex Pathways Academic Background Motor control is one of the essential functions of the nervous system, and spinal reflex pathways play a key role in this process. In animal studies, voltage-sensitive calcium channels (VSCCs) have been identified as critical factors in regulating t...
