Champalimaud Researcher Receives two million euros grant from the European Research Council to study defensive strategies, from neurons to behaviour

Marta Moita, Deputy Director of the Champalimaud Research Programme and group leader of the Behavioural Neuroscience lab at the Champalimaud Centre for the Unknown, in Lisbon – Portugal, was awarded a two million euros grant from the European Research Council (ERC) to advance her innovative work on the neural basis of defensive behaviours.

Tumour cells conquer territory from their neighbours using a newly discovered mechanism

Despite decades of cancer research, the early phases of tumour progression that connect the appearance of few abnormal cells to the formation of a clinically detectable tumour mass remains poorly understood. It was previously proposed that certain mutations could give a competitive advantage to a subset of cells that would enable them to kill and replace their neighbours, thereby initiating a cancerous tumour. Yet, the mechanisms at the basis of such competition were not clear.

Losing neurons can sometimes not be that bad

For the first time, scientists at the Champalimaud Centre for the Unknown (CCU), in Lisbon, Portugal, have shown that neuronal cell death in Alzheimer’s disease (AD) may actually not be a bad thing – on the contrary, it may be the result of a cell quality control mechanism trying to protect the brain from the accumulation of malfunctioning neurons.

Life of PI: Searching for the mechanistic explanations of brain function

For most of his scientific career, Alfonso Renart has been working at the frontier between computational and experimental neuroscience, developing mathematical models that try to explain salient properties of the activity of neurons in cortical circuits and how these embody the computations that underlie cognition.

I feel like I’m still very much searching for a way to describe the essence of what it means to be a living organism in purely physical terms.Alfonso Renart

Where is George? Ask this software to look at the crowd

Idtracker.ai is a mix of conventional algorithms and artificial intelligence developed at the Champalimaud Centre for the Unknown. From the video footage of a moving crowd composed of dozens of individuals, it learns to identify each and every individual in that crowd. The Collective Behavior lab has now shown that it takes about an hour for idtracker.ai to identify each and every one of 100 zebrafish in a video, at all times, with almost 100% accuracy.

Mapping the neural circuit of innate responses to odors

The innate capacity to discern between an appetizing and a foul – i.e. dangerous – odor is essential, from the start, to guide behavior for survival. Until now, little was known about how these innate olfactory responses are hard-wired in the brain. A team of neuroscientists at the Champalimaud Centre for the Unknown has performed one of the first studies into the central neural circuits that underlie these innate responses.

Untangling the where and when of walking in the brain

How do our brains know when and where to place our feet in order to prevent us from tripping each time we find ourselves on a new terrain such as a icy path, or a sandy beach? In an innovative study, the Neural Circuits and Behaviour Lab, finds remarkable similarities between the way humans and mice learn to adapt their manner of walking and pinpoint a site in the brain that controls two components crucial for mastering this task – space and time.

Science Snapshot: Untangling Space and Time in the Brain

How do our brains know when and where to place our feet in order to prevent us from tripping each time we find ourselves on a new terrain such as an icy path, or a sandy beach?

In an innovative study, scientists from the Neural Circuits and Behaviour lab (careylab.org), find remarkable similarities between the way humans and mice learn to adapt their manner of walking and pinpoint a site in the brain that controls two components crucial for mastering this task – space and time.

Solving the "Catch 22" of rectal cancer

When rectal cancer infiltrates adjacent lymph nodes, patients may have a better clinical outcome if chemotherapy or radiotherapy are administered prior to the standard surgery to remove the tumour. However, the status of these lymph nodes can only be precisely assessed upon removal during surgery.

Science Snapshot: Deciphering the Magnetic Signature of Cancer

A multidisciplinary team of scientists and clinicians at the Champalimaud Centre for the Unknown, developed a new noninvasive MRI methodology, called SPI (Susceptibility Perturbation MRI), that is able to identify whether lymph nodes have been infiltrated by malignant cells with high accuracy in rectal cancer patients.

Such a characterisation can help define treatment strategy for rectal cancer patients and may have future implications for other malignancies.
