The Functional Role of Gamma Band Activity - Lessons from MEG

About this Research Topic

In recent years magnetoencephalography (MEG) has been intensively used to scrutinise the functional role of cortical gamma band activity, i.e. the oscillatory brain activity at 30-100 Hz.

In recent years magnetoencephalography (MEG) has been intensively used to scrutinise the functional role of cortical gamma band activity, i.e. the oscillatory brain activity at 30-100 Hz. Thus, gamma band activity has been observed in primary sensory cortices, e.g. the primary visual, motor, somatosensory and auditory cortices. It has been shown that gamma band activity plays a crucial role and is modulated by varied cognitive tasks, memory and pathophysiology. Moreover, it has been suggested that gamma band activity interacts with activity in other frequency bands, e.g. alpha and theta band activity. However, the functional role of human gamma band activity is not yet fully understood and further research is needed to enlighten its full functional meaning and implications.
This Research Topic aims to summarise and review where the MEG community stands today in studying gamma band activity. What has been achieved? Which questions still remain to be solved?
Moreover, it will present current activities in the field. What are the hot topics today and what are the emerging findings right now?
In addition to this, implications from other fields of research, such as animal studies examining the functional role of gamma band activity will be integrated and discussed.
Last but not least, this Research Topic aims to identify prospective directions for the field, trying to inspire the future work of researchers. Which questions on gamma band activity have to be tackled in the near future?
Researchers are welcome to contribute experimental reports, perspectives and reviews.
