Real-life Examples of Ventral Attention Network in Action

📚 Quick Study Guide

🧠 The Ventral Attention Network (VAN) is crucial for reorienting attention to unexpected but relevant stimuli. 🧭 It's primarily located in the right hemisphere of the brain. 📍 Key regions include the temporoparietal junction (TPJ) and the ventral frontal cortex (VFC). ⚠️ VAN is activated when attention needs to be shifted from a current focus to something new or salient. 🔄 Unlike the Dorsal Attention Network (DAN), which is involved in sustained, voluntary attention, VAN is more reactive. 🚦 VAN helps in detecting salient stimuli, especially when those stimuli are behaviorally relevant. 💡 Dysfunction in the VAN can lead to difficulties in attention shifting and impaired awareness of surroundings.

Practice Quiz
