More serotonin, less motivation? It depends on the circumstances
[Short] stimulations [of serotonin-producing neurons] reduced the animals’ motor activity only when they were freely exploring a new environment, with no directed ‘goals’. (...) Long term stimulation triggered a second effect: the mice became globally more active. – Patrícia Correia
Simple rule explains complex group swimming patterns
In an article published in the scientific journal PNAS, researchers from the Collective Behaviour lab at the Champalimaud Centre for the Unknown (CCU) present a surprisingly simple rule that explains how complex patterns of collective movement emerge in zebrafish as they develop from recently hatched larvae into adults.
From brouhaha to coordination: motor learning from the neuron's point of view
In the [animal] motor cortex, activity is highly variable at the beginning [of motor learning] and then becomes consistent, not so variable – it crystallizes. So Vivek [Athalye] wanted to know: “Can we devise a way to see how the brain does this?” – Rui Costa
An alternative America - How will the Trump Administration impact science?
How will this new administration impact science? What will be the role of scientists in the years to come? To find out what is the perspective of american scientists on this topic, we spoke with three US-born researchers at Champalimaud Centre for the Unknown: Baylor Brangers, Tracy Pritchett and Aaron Koralek.
