Echoes of the Brain
Transmodal (nonsensory-specific) regions sit at the confluence of different information streams, and play an important role in cognition. These regions are thought to receive and integrate information from multiple functional networks. However, little is known about (1) how transmodal cortices are functionally organized and (2) how this organization might facilitate information processing. In t...
متن کاملEchoes of the brain within the posterior cingulate cortex.
There is considerable uncertainty about the function of the posterior cingulate cortex (PCC). The PCC is a major node within the default mode network (DMN) and has high metabolic activity and dense structural connectivity to widespread brain regions, which suggests it has a role as a cortical hub. The region appears to be involved in internally directed thought, for example, memory recollection...
متن کاملPerceptual Echoes at 10 Hz in the Human Brain
The occipital alpha rhythm (∼10 Hz) is the most prominent electrophysiological activity in the awake human brain, yet its functional role and relation to visual perception are little understood. Transient stimuli normally elicit a short series of positive and negative deflections lasting between 300 and 500 ms: the visual-evoked potential (VEP). Alpha oscillations, on the other hand, are genera...

متن کاملEchoes of the Month
The Paris Morgue is no more. It is to be replaced by an entirely new type of institution. The original Morgue, which overhangs the riverside close by Notre Dame, was founded in 1864. It was devoted to the reception of the bodies of those to whom death had come by other than natural means, and the bodies of people who had met with violent ends were in manjr cases preserved there for many years u...
