Gestalt rules are over 100 years old. But how do they show up in neurons? We find that convexity & closure define figures, boost perceived contrast and enhance responses in V1 and V4 of visual cortex, even when figureness is irrelevant. eur05.safelinks.protection.outlook.com?url=https%3A...

Our new paper in Brain Stimulation by Antonio Lozano et al.: NEUmap rapidly maps visual percepts for cortical visual prostheses using spontaneous neural activity. Validated in macaques and blind humans, with <1s of data. www.brainstimjrnl.com/article/S193...

Predictive coding has guided neuroscience for years but it does not account for the neuronal data. We review how patterns of feedback during spatial and temporal predictions are better captured by a family of opposing theories, collectively termed BELIEF. doi.org/10.1016/j.ti...

In this short letter we explain why binding problems occur in the brain and why deep neural networks need to cope with them. We respond to Scholte and de Haan (TICS 2025), who claimed the opposite. lnkd.in/euNaS6eu

We have a PhD-position at the institute de la Vision in to develop optogenetic stimulation in macaques to induce and refine artificial vision for blind people. For information about the position and the application procedure, see www.institut-vision.org/en/job-offer...
