Abstract

Gamma-band activity, peaking around 30-100 Hz in the local field potential's power spectrum, has been found and intensively studied in many brain regions. Although gamma is thought to play a critical role in processing neural information in the brain, its cognitive functions and neural mechanisms remain unclear or debatable. Experimental studies showed that gamma rhythms are stochastic in time and vary with visual stimuli. Recent studies further showed that multiple rhythms coexist in V1 with distinct origins in different species. While all these experimental facts are a challenge for understanding the functions of gamma in the visual cortex, there are many signs of progress in computational studies. This review summarizes and discusses studies on gamma in the visual cortex from multiple perspectives and concludes that gamma rhythms are still a mystery. Combining experimental and computational studies seems the best way forward in the future.

摘要

伽马波段活动在局部场电位功率谱中于30 - 100赫兹左右达到峰值，已在许多脑区被发现并得到深入研究。尽管伽马波段被认为在大脑神经信息处理中起关键作用，但其认知功能和神经机制仍不明确或存在争议。实验研究表明，伽马节律在时间上是随机的，并且会随视觉刺激而变化。最近的研究进一步表明，在初级视皮层（V1）中多种节律共存，且在不同物种中有不同的起源。虽然所有这些实验事实对理解伽马波段在视觉皮层中的功能构成挑战，但在计算研究方面有许多进展迹象。本综述从多个角度总结并讨论了关于视觉皮层中伽马波段的研究，得出结论：伽马节律仍是一个谜。未来将实验研究与计算研究相结合似乎是最佳前进方向。
