A Thalamic Hub-and-Spoke Network Enables Visual Perception During Action by Coordinating Visuomotor Dynamics

Neural Mechanisms of Visual Perception and Motor Coordination Academic Background In daily life, animals need to distinguish sensory experiences caused by the external environment from those elicited by their own movements. This distinction is crucial for accurate perception and motor control. However, the diversity of behaviors and their complex i...

Neural Mechanisms of Relational Learning and Fast Knowledge Reassembly in Plastic Neural Networks

Neural Mechanisms and Relational Learning: Rapid Knowledge Reassembly in Neural Networks Background Humans and animals possess a remarkable ability to learn relationships between items in experience (such as stimuli, objects, and events), enabling structured generalization and rapid information assimilation. A fundamental type of such relational le...

Experience-Dependent Dopamine Modulation of Male Aggression

Experience-Dependent Dopamine Modulation of Male Aggression in Mice Academic Background Aggression is a common social behavior in the animal kingdom, crucial for territory defense, resource competition, and mate protection. Although the role of dopamine in regulating aggression has been extensively studied, its specific neural mechanisms remain unc...

Impact of Different Muscle-Lengthening Amplitudes Combined with Electrical Nerve Stimulation on Torque Production

The Impact of Muscle Lengthening and Electrical Nerve Stimulation on Torque Production Academic Background In rehabilitation and training programs, Neuromuscular Electrical Stimulation (NMES) is an effective method for enhancing skeletal muscle function. However, traditional high-intensity NMES, while capable of generating high torque, often comes ...

Days-Old Zebrafish Rapidly Learn to Recognize Threatening Agents Through Noradrenergic and Forebrain Circuits

This study explores the necessity of quickly recognizing and avoiding predators in the natural environment, which is crucial for juvenile animals due to their increased vulnerability to predators. However, it remains unclear whether neonatal vertebrates can rapidly acquire such skills and the underlying neural mechanisms. Zebrafish, a widely used m...
