在神经功能和行为输出之间建立因果关系仍然是一个具有挑战性的问题。常用的扰动技术能够对内在活动模式进行前所未有的控制,并且可以有效地识别对特定行为重要的关键电路元件。然而,这些方法可能会严重扰乱活动,妨碍对特定大脑区域内即时神经动力学的行为相关性的研究。在这里,我们讨论应用轻度局部冷却来减缓内在神经回路活动,同时保留其整体结构。使用网络建模和来自多个物种的示例,我们强调了焦点冷却的力量和多功能性,以了解神经动力学如何控制行为,并主张其在系统神经科学界得到更广泛的采用。班纳吉等人。展示了局部冷却神经回路作为测试大脑动力学和行为之间联系的一种手段的强大功能和多功能性,并使用来自多个物种的示例以及网络模拟来支持这一观点。
Establishing a causal link between neural function and behavioral output has remained a challenging problem. Commonly used perturbation techniques enable unprecedented control over intrinsic activity patterns and can effectively identify crucial circuit elements important for specific behaviors. However, these approaches may severely disrupt activity, precluding an investigation into the behavioral relevance of moment-to-moment neural dynamics within a specified brain region. Here we discuss the application of mild focal cooling to slow down intrinsic neural circuit activity while preserving its overall structure. Using network modeling and examples from multiple species, we highlight the power and versatility of focal cooling for understanding how neural dynamics control behavior and argue for its wider adoption within the systems neuroscience community. Banerjee et al. demonstrate the power and versatility of focally cooling neural circuits as a means of testing the link between brain dynamics and behavior, supporting this view using examples from multiple species as well as network simulations.
