The Story of the 120-Cell, Volume 48, Number 1

O ne of the most beautiful objects in mathematics is the regular polytope in R4 whose boundary consists of 120 dodecahedral cells. This 120-cell is a rarity among rarities because it lives in three very special worlds. Its home is among the regular polytopes in R4, but it also lives in the remarkable sphere S3 and in the quaternions H. And if this is not enough, the 120-cell encodes the symmetr...

Spatiotemporally organized waves are among the most ubiquitous activity patterns in the brain. Recent advances in electrophysiology, imaging, and other technologies allow experimentalists to observe these activity patterns simultaneously in the responses of many individual neurons and in the ensemble response of the neural circuit, both in vivo (the whole animal/subject) and in vitro (e.g., cul...
