by Massachusetts Institute of Technology A) Neural field model and connections. Neural fields provided a quantitative way to describe each ensemble’s patterns of activity across simultaneously recorded sites. The same model can describe different ensembles. Each electrode occupies a position on a cortical manifold (line) Δ parameterized by the variable x and is connected to all...
Electric fields may represent information held in working memory, allowing the brain to overcome “representational drift,” or the inconsistent participation of individual neurons. As the brain strives to hold information in mind, such as the list of groceries we need to buy on the way home, a new study suggests that the most consistent and...

Pulsing cells with electric fields can force calcium diffusion into cells. Researchers have now optimized this technique in an attempt to kill cancer cells and leave healthy cells intact. Researchers from the Bioelectrics Department of Kumamoto University (Japan) have identified the optimal pulsed electric field (PEF) conditions for the maximum calcium cell membrane permeability. There...
