Topic: Hierarchical Gaussian Filtering

Beliefs and expectations, also referred to as priors, shape how we perceive our environment. In a complex and ever-changing world, prior beliefs need to be flexibly and continuously integrated into sensory decision processes to guide adaptive behavior. Despite the advances in understanding the integration of priors in visual decisions at the computational and algorithmic levels, its neural mechanisms remain unclear. The goal of this study was to understand the neural dynamics involved in belief formation and updating. Here, we used high-density electroencephalogram recordings to constrain and
