Disruption of Nucleolar Integrity and Dysregulation of RNA Splicing in C9orf72-FTD/ALS Background and Research Motivation The hexanucleotide repeat expansion (GGGGCC)n in the C9orf72 gene is the most common genetic cause of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). Studies have shown that these repeat sequences not only...
Exploring the Crucial Role of the Motor Cortex in Basal Ganglia and Dynamic Motor Control Research Background and Motivation The role of the motor cortex (Motor Cortex, M1) in motor generation and regulation has long been a significant topic in neuroscience. The interaction between M1 and the striatum in selecting and executing goal-directed action...
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 ...
Scientific News Report: The Molecular and Neural Circuit Mechanisms in the Globus Pallidus for Controlling Cocaine-Induced Behavioral Plasticity In the field of the neurobiology of drug abuse, this paper provides a new perspective for exploring cocaine-induced behavioral plasticity and neural circuit regulation. The research team centered on the Gl...
I. Research Background The taste of food has a significant impact on the feeding motivation of animals. Previous research has shown that taste, as a positive feedback signal, can enhance the feeding motivation of animals. However, in recent years, studies on whether taste also plays a role in suppressing feeding and helping achieve negative feedbac...
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...
With the advancement of neuroscience research, the crucial role of N-methyl-D-aspartate receptors (NMDA receptors, NMDAR) in neurotransmission and cognitive functions has become increasingly clear. NMDARs are a type of ionotropic glutamate receptor that play an important role in neuronal synapses, responsible for rapid excitatory transmission and s...
Antisense Oligonucleotide Enhances SLC20A2 Expression and Inhibits Brain Calcification in Humanized Mouse Models Background and Research Questions Primary Familial Brain Calcification (PFBC) is an age-related neurogenetic disorder, characterized by bilateral calcifications in brain regions such as the basal ganglia, thalamus, and cerebellum. PFBC p...
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...
Reversible Regulation of Retinal and Peripheral Nerve Function: Physiological Study of Serine and Glycine Background and Research Motivation Macular Telangiectasia Type 2 (Mactel) is an age-related retinal disease characterized by central vision loss. The molecular etiology of this disease is complex and is primarily associated with the metabolism ...
