Episodic memory must accomplish two adversarial goals: encoding and storing a multitude of experiences without exceeding the finite neuronal structure of the brain, and recalling memories in vivid detail. Dimensionality reduction and expansion (‘dimensionality transformation’) enable the brain to meet these demands. Reduction compresses sensory input into simplified, storable codes, while expansion reconstructs vivid details. […]

Responding to Adam Zeman’s excellent article in TiCS on aphantasia [1], Michel et al. [2] raise the intriguing possibility that aphantasia represents a case of access consciousness without phenomenal consciousness of mental imagery. This entails that people with aphantasia could perform tasks using mental imagery, while being unaware of doing so. Read Full Article (External […]

Traditionally considered a motor structure, the cerebellum has been shown to play a key role in several cognitive functions. However, for decades, the cerebellum has been largely overlooked and even deliberately excluded from ‘whole-brain’ neuroimaging studies. Here, we propose that the continued exclusion of the cerebellum has limited our understanding of whole-brain function. We describe […]
