Context

Karavela is a neuroscience research company established in 2025 and currently based in Paris, France. We build a foundation model of the human brain relying on next-generation magnetic resonance. To do so, Karavela is collecting a very large MRI dataset from healthy volunteers listening to naturalistic stimuli (e.g., audiobooks, podcasts, radio programmes). This dataset is then used to train deep learning models that can reconstruct the stimuli from recorded brain activity. The goal is to leverage the representations learnt by these models in downstream applications, in particular by providing biomarkers for neurological and psychiatric diseases in clinical trials. Karavela is currently organised into 3 teams that each focus on one of the aforementioned aspects: data collection, model development, and clinical applications.
