Have you ever felt like your surroundings look unreal? Our new Registered Report (accepted in Neuroscience of Consciousness) studied derealisation and shows that altered visual experiences don’t change how we assess vividness. To find our more:

Adaptive learning is coordinated across behaviour, time and neurobiology (from synapses and dendrites, to astrocytes and the systems level). If you’ve ever wondered how noradrenaline helps shape these multiscale learning processes, you might like this:

Social rejection sucks, but they also provide a learning signal. Here we show that the two aspects of social rejection can be dissociated using computational modeling and neuroimaging. Delighted to have been able to be part of this work, definitely one of the most fun collaborations I've had!
