Recent studies (Hu and Iannetti Proc. Natl. Acad. Sci. U. S. A. 2019;116:1782–1791 and Tan et al. Nat. Commun. 2019;10:983) in animals and humans provide converging evidence that gamma oscillations in the primary somatosensory cortex are closely and causally related to pain behavior and pain perception. These findings could help to identify brain-based markers of […]

Most research in cognitive neuroscience explores how external stimuli are processed by the brain. However, the brain also receives input from the internal body. We discuss here how the heart and gastrointestinal (GI) tract intrinsically generate their own electrical activity, thereby continuously sending information to the brain. These ongoing ascending signals actively shape brain dynamics […]
