A Human Pluripotent Stem Cell-Based Somitogenesis Model Using Microfluidics

Study of Somite Formation Model Based on Microfluidic System Background and Research Motivation The formation of somites plays a crucial role in vertebrate embryonic development, significantly influencing the layout and functionality of the embryonic musculoskeletal system. Somite formation involves the segmentation of bilateral presomitic mesoderm...

Integration and Competition Between Space and Time in the Hippocampus

A Review on the Mechanisms of Spatial and Temporal Integration and Competition in the Hippocampus Research Background and Significance In the human and animal brain, space and time comprise the primary dimensions of episodic memory, playing a crucial role in encoding information such as event sequences, locations, and durations. It has long been fo...

A Neural Basis of Choking Under Pressure

The Neural Basis of Underperformance Under Pressure: An Analysis of the Interaction Between Reward Signals and Motor Preparation in Primate Brains Research Background “Choking under pressure” refers to situations where individuals fail to perform as expected due to the stress of important moments, as often seen with professional athletes during cri...

Flexible Control of Sequence Working Memory in the Macaque Frontal Cortex

Research Background In our daily lives, Sequence Working Memory (SWM) is crucial; for example, when filling in a birth date, the year, month, and day need to be recalled and arranged in a specific order. However, how the brain controls information in sequential memory and flexibly orders information under different task demands remains an unsolved ...

Transformation of Neural Coding for Vibrotactile Stimuli Along the Ascending Somatosensory Pathway

Research Background The neural transduction mechanisms of tactile vibration coding have been a hot topic in neuroscience research. In daily life, we acquire information about the external environment through the perception of vibrations, such as phone vibration alerts or car proximity warnings. In mammals, high-frequency vibration perception is mai...

Structural Basis of Psychedelic LSD Recognition at Dopamine D1 Receptor

Structural Basis of LSD Recognition in Dopamine D1 Receptors Research Background and Problem Statement LSD (lysergic acid diethylamide) is a well-known hallucinogen that primarily exerts profound cognitive and perceptual effects by acting on various neurotransmitter receptors, including serotonin (5-HT) receptors and dopamine receptors. The 5-HT2A ...

In a study titled “Visual Experience Reduces the Spatial Redundancy between Cortical Feedback Inputs and Primary Visual Cortex Neurons,” Rodrigo F. Dias, Radhika Rajan, and their team explored how visual experience influences the spatial redundancy of cortical feedback pathways. This research was carried out by scientists from the Champalimaud Neur...

Super-relaxed Myosins Contribute to Respiratory Muscle Hibernation in Mechanically Ventilated Patients

The Impact of Super-Relaxed Myosin on Diaphragm Dysfunction in Ventilated Patients Background Weak diaphragm contraction is a common problem in patients receiving mechanical ventilation in intensive care units (ICUs). This leads to difficulties in weaning patients off ventilators, increases mortality rates, and imposes a significant economic burden...

Revisiting Distinct Nerve Excitability Patterns in Patients with Amyotrophic Lateral Sclerosis

“Revisiting Distinct Nerve Excitability Patterns in Patients with Amyotrophic Lateral Sclerosis” Academic Background Amyotrophic Lateral Sclerosis (ALS) is a devastating neurodegenerative disease characterized by the progressive loss of central and peripheral motor neurons. Although the disease is clinically and genetically heterogeneous, axonal hy...
