Gamma神经振荡和信息整合加工 postprint

Abstract: The Gamma oscillation is one kind of neural interaction activities. The characteristics of the Gamma oscillation contribute to its important role in information binding process. A large body of research has demonstrated that binding the sensory signal from multiple channels at the perceptual level is associated with the gamma oscillatory synchronization in sensory cortex (e.g. visual cortex, auditory cortex), whereas binding the information from single channel at the conscious level is associated with the enhanced Gamma oscillations in higher cortex (e.g. temporo-parietal cortex). The functions of Gamma oscillations in information-binding process have been described in several theoretical frameworks, including Neural Coupling model and Match & Utilization model. However, extreme caution should be exercised when Gamma oscillations were applied as an index of binding process. What roles of Gamma oscillations play in a complex binding process should be investigated in the future.
