Now accepted and published --- with many thanks to the referees for helping sharpen the manuscript. Long time since the first notes. Good to see it officially out. www.cell.com/current-biol...

A vector navigation and inference architecture can construct universal cognitive maps for abstract reasoning
Bicanski proposes an algorithm and neural mechanisms for the iterative construction of abstract cognitive maps via non-local inference. Map positions are triangulated and memorized by a set of extant ...

1/N: Dear cognitive map fans, I’d like to share a model I’ve been working on for a while (clearing backlog :). I show how a vector navigation architecture (VNA) and a “positional inference network” (PIN) can build Universal Cognitive Maps (UCMs) for abstract spaces. www.biorxiv.org/content/10.6...

A Passage of Time Signal in the Human Brain
In a dense-sampling resting–state functional magnetic resonance imaging study, Wang et al. (2025) recorded two individuals’ functional connectivity patterns over 30 consecutive days to find a marker o...

Our new paper, now published in @natcomms.nature.com , asks a simple question: when two tasks share a common structure, does the brain learn them more efficiently? Surprisingly, this was not the case. Thread below (1/7) rdcu.be/eSwvU

The effects of task similarity during representation learning in brains and neural networks
Nature Communications - Here, the authors show learning tasks with similar structures can initially cause interference and slow down learning, but both the brain and artificial networks gradually...

🚨 New preprint! Impact of Task Similarity and Training Regimes on Cognitive Transfer and Interference 🧠 We compare humans and neural networks in a learning task, showing how training regime and task similarity interact to drive transfer or interference. www.biorxiv.org/content/10.1...

Impact of Task Similarity and Training Regimes on Cognitive Transfer and Interference
Learning depends not only on the content of what we learn, but also on how we learn and on how experiences are structured over time. To investigate how task similarity and training regime interact dur...

Happy to share the results of a new exp done in collaboration with Rena Bayramova and Christian Doeller at MPI_CBS, and Roberto Bottini at CIMeC/UniTrento, now out in Nat Comms :) “Mental search of concepts is supported by egocentric vector representations and restructured grid maps” rdcu.be/ds67W
