We found that two different regions within the brain seem to play very different roles in the generation of action timing. One area appears to keep track of the ideal waiting time based on experience. A second area also keeps track of the ideal timing, and in addition shows variability that renders individual decisions unpredictable. – Zach Mainen

Bruno Costa-Silva, principal investigator at Champalimaud Research, was awarded yesterday (May 30) the Crioestaminal/Associação Viver a Ciência Prize for biomedical research.

The winning project, which was selected among three finalists, is titled: “The role of pancreatic cancer-derived exosomes in mediating bone marrow cell recruitment to the pre-metastatic liver”.

Appearances can be deceiving. When looking at the outmost layer of the brain, called the neocortex, it looks like a simple sheet of neurons. But the truth is far from it. This “simple sheet” has a complex sub organization of its own. And not only that, the neocortex is the brain structure that endows us with advanced cognitive abilities, such as thought and language.

Faced with imminent danger, parents will unconditionally defend their young instead of ensuring their own safety. Scientists have now discovered that it is the release of the so-called “love hormone” – oxytocine – into the amygdala, a brain structure known for its crucial role in the processing of emotional reactions, that accounts for a mother’s behavior when it comes to protecting her offspring.

Scientific progress and Open Science go hand in hand. Open Science includes the sharing of data, techniques and ideas, which drives scientific progress by enabling scientists to build on each other’s work to make further discoveries. Ultimately, these discoveries produce major benefits for society in all fields including medicine and health.

To promote Open Science practice in EU, the European Commission has been taking a series of steps, which include the organisation of the international workshop held at the CCU earlier this week.

On Tuesday June 27, 2017, the Portuguese neuroscientist Rui Costa, principal investigator at the Champalimaud Centre for the Unknown, in Lisbon, Portugal, and Professor of Neuroscience at Columbia University, in New York, was awarded the Ariëns Kappers Medal at the Netherlands Institute for Neuroscience (NIN), in Amsterdam.

Chemotherapy is an important, life-saving treatment for breast cancer. But it’s not risk free. While some of its side effects are short-term and reversible, others are not and could even result in severe repercussions to the patient’s health. It is therefore of paramount importance that doctors would be able to assess whether the benefits of administering chemotherapy outweigh the risks on a case by case basis.

It is a part of every waking moment of our lives. But whenever scientists have tried to study it, consciousness has slipped through their fingers. Will we ever understand why we have it and how it arises in our brains?

“There seems to be a big gap between the physical universe, that has these objective properties, and one’s own feelings, sensations – this inner world that no one else has any access to. These two things seem to have nothing to do with one another.” – Zach Mainen
