The human brain consists of a highly complex network of about 85 billion nerve cells (neurons) that constantly exchange information. To function, all these cells have to organise the production, transport, storage and recycling of countless different molecules such as neurotransmitters, mRNA and proteins - a gigantic logistical challenge at the molecular level. So how do they organize these processes to be both robust and efficient? How do problems in solving these logistical challenges relate to brain diseases such as Alzheimer's or Parkinson's disease? To discuss these questions, neuroscientists from all over the world will meet from 28 August for the 3rd Giersch International Symposium at the Frankfurt Institute for Advanced Studies (FIAS).
