Professor Ma Jian on Ablation of Difficult Right-Sided Bypass: Possible Causes and Strategies

The main causes of atrioventricular reentrant tachycardia include atrioventricular bypass (Kent bundle), atrioventricular His bundle bypass (James bundle), junctional-ventricular bypass (Mahaim bundle), and bundle-ventricular bypass (Mahaim bundle). Atrioventricular bypass (Kent bundle) presents as WPW syndrome, short P-R interval, and δ wave; while atrioventricular His bundle bypass (James bundle) shows L-G-L syndrome on ECG, short P-R … Read more

Scientists Reveal Reward Learning Pathway Mediated by Somatostatin Neurons

Assessing the positive or negative valence of external sensory cues and translating them into appropriate behavioral responses is crucial for animal survival in complex or challenging environments. Negative valence signals lead to aversive/avoidance behaviors, while positive valence signals promote reward/approach behaviors. Much previous research has focused on the neural structures within the emotional processing network … Read more
