Action-selection is determined by a combination of goal-directed and habitual processes. Habits are defined as the reward-independent, stimulus-response relationships which form when an action is regularly executed in the same context, regardless of outcome. An influential computational model proposes that habit format...

Effective decision making in stochastic environments requires balancing flexible, value-based learning with a stabilising influence of habitual action selection. While dopamine-mediated reward prediction errors (RPEs) are a well-established component of value learning, the mechanisms underlying habit- like behaviour re...

Beta oscillations (13–35 Hz) in the subthalamic nucleus (STN) are a hallmark of Parkinson’s disease (PD), yet little is known about their spatial dynamics. Since traveling waves (spatially propagating oscillations) have been observed in cortical and subcortical structures at different frequencies, we hypothesized that...

The ability to extract and exploit temporal structure across diverse tasks is central to human cognition. Neuroscientists have typically relied on recurrent neural networks (RNNs) trained with backpropagation through time (BPTT) when modelling neural and behavioural processes such as decision-making and motor control....
