  1. Is it possible to reset our biological clocks? A study shows, for the first time, that the peripheral biological clocks located in white blood cells can be synchronized through the administration of glucocorticoid tablets. See abstract at: Glucocorticoids entrain molecular clock components in human peripheral cells
  2. Implanting fear: Two mechanisms work in tandem to form memories of frightening events. The formation of memories of fearful experiences involves not only changes in brain wiring, but also the action of a chemical known as noradrenaline. Armed with this knowledge, a research team succeeded in inducing a fear memory without an electric shock. “We were able to artificially implant a fear memory based on a better understanding of the plasticity mechanisms,” says researcher Joshua Johansen.

Hebbian and neuromodulatory mechanisms interact to trigger associative memory formation. Proceedings of the National Academy of Sciences USA 111, 51 (2014). doi: 10.1073/pnas.1421304111
  3. Neuroscientists investigate how 100 billion nerve cells produce a clear thought or an action. The neuroscientists Dr. Michael Strüberand Prof. Dr. Marlene Bartos from the University of Freiburg and their colleague from Vienna Prof. Dr. Peter Jonas have discovered that the distances between communicating cells play a part in the regulation of brain networks. The team presents this approach in the current issue of the journal Proceedings of the National Academy of Sciences (PNAS): Michael Strüber, Peter Jonas, Marlene Bartos. (2015) Strength and duration of perisomatic GABAergic inhibition depend on distance between synaptically connected cells. Proceedings of the National Academy of Sciences USAdoi: 10.1073/pnas.1412996112
  4. Electrical stimulation ‘tunes’ visual attention using long-term memory. Researchers claim our brains can be electrically “tuned” to enable us to do a much better job of finding what we’re looking for, even in a crowded and distracting scene. The new findings, published Dec. 1, 2014, in the Proceedings of the National Academy of Science, challenge our current understanding of how visual attention is focused and the roles of short- and long-term memory.
