The Brain Encodes Pure Logic Beyond Natural Language And At The Boundaries With Mathematics

The paper investigates how the brain processes pure logic by comparing neural activity during logic, language, and arithmetic tasks, finding distinct brain circuits for logic.

The effects of task similarity during representation learning in brains and neural networks

This study shows that task similarity during learning can impair performance, with neural and network models showing reduced orthogonality in representations for similar tasks.

Foraging in conceptual spaces: hippocampal oscillatory dynamics underlying searching for concepts in memory

The paper investigates how the brain accesses stored knowledge by comparing conceptual search to foraging in physical space, finding hippocampal theta power increases and theta-gamma coupling during semantic memory retrieval.

Impact of Training Regimes and Task Similarity on Learning and Cognitive Transfer

The paper investigates how task similarity and training regime affect learning and transfer, finding that blocked training improves performance on similar tasks, while interleaving hinders it, with an asymmetric effect based on task order.

Hippocampal-entorhinal cognitive maps and cortical motor system represent action plans and their outcomes

The paper shows that hippocampal-entorhinal circuits and SMA represent action plans and their outcomes, with hippocampal activity scaling with outcome similarity and SMA responding to overlapping actions.

Mental search of concepts is supported by egocentric vector representations and restructured grid maps

This study shows that mental search involves egocentric vector representations and restructured grid maps in the parietal cortex during conceptual task performance.

Multiple spatial codes for navigating 2-D semantic spaces

The paper investigates how the brain represents abstract semantic spaces using spatial coding mechanisms similar to those used in physical navigation.

How emotional memory affects face remembering: an ERP investigation

This study investigates how emotional memory affects face remembering using ERP signals, finding that emotional valence enhances memory traces and that temporal recency influences neural responses.
