Three postdocs receive the Brain Award

 Brain Award for Methodological Excellence

 

BrainAward1This years postdoc Brain Award for Methodological Excellence has been won by Julliette Cheyne for her paper ‘Spontaneous activity drives local synaptic plasticity In Vivo’ which was published in Neuron. “Juliette Cheyne co-authored a study that observed spontaneous synaptic plasticity during development and discovered a simple plasticity rule, summarized as ‘out of sync, lose your link’. To observe this effect, the authors developed an impressive approach that combines whole-cell recordings with two-photon calcium imaging in neonatal mice,” said  Lukas Kaptein, one of the jury members.

Brain Award for scientific excellence

For the first time this year, the postdoc Brain Award for scientific excellence was given to two scientists; Jeannette Lorteije and Ariel Zylberberg. They have received this award for their paper ‘The formation of hierarchical decisions in the visual cortex’ which was published in Neuron. Since the two authors contributed equally the members of the jury concluded that the award should be given to both Lorteije and Zylberberg. They both received a sculpture an each was given half the cash award.

Synapse and Network Development

The development of specific synaptic connections between nerve cells is a fundamental step during the maturation of the brain, but its underlying mechanisms are largely unknown. To investigate how neurons establish specific connections, we apply high resolution imaging and electrophysiology in brain slices and in vivo.

Our goal is to identify patterns of neuronal activity, forms of calcium signaling and molecular factors that regulate synapse development. We focus on the local regulation of synapse maturation and its relationship with activity patterns in the entire cell and the emerging network.

Roelfsema Group

The Vision and Cognition group is led by Dr. Pieter Roelfsema, also director of the Netherlands Institute for Neuroscience. Research of this group is directed at understanding cortical mechanisms of visual perception, memory and plasticity. One of our goals is to create a visual cortical prosthesis to restore vision in blind people.
