This recursive exchange of signals suppresses the prediction error at each level and provides a hierarchical explanation for sensory inputs that enter at the lowest (sensory) level. The neuronal activity of the entire hierarchy encodes beliefs (or probability distributions) over states in the world ...
The gastrointestinal mucus layer represents the last barrier between ingested food or orally administered pharmaceuticals and the mucosal epithelium. This complex gel structure plays an important role in the process of small intestinal absorption. It pro
This explanation is compelling in its simplicity, but it is far from clear that it provides the complete picture of what is happening. Competition between sources and sinks of cold gas can plausibly balance each other, but it is worth noting that there is little evidence for evolution of the...
Magnetic Resonance Imaging (MRI) has become the reference imaging technique for the diagnosis and prognosis of many cancers. It is also an ideal biomedical imaging technique for monitoring therapeutic efficiencies. In addition, cellular MRI enables the detection and tracking of cells within the whole ...
