During sleep, the brain weakens the connections among nerve cells, apparently conserving energy and, paradoxically, aiding memory

Brains, even of relatively simple organisms like fruit flies, are teeming with a huge variety of nerve cells that can behave differently depending on their connections, task and even time of day.

It may, for example, partly account for the differences in brain structure and behavior between identical twins, and could even affect thought processes by subtly influencing the changes in nerve cell connections that occur with experience.

The three scientists assembled small aggregates of nerve cells, known informally as «mini-brains,» and used them to study how specific groups of neurons in the brain find each other and establish connections.
