The paper proposes experiments to distinguish mechanisms underlying hexadirectional fMRI modulations linked to grid-cell activity.

The paper reanalyzes grid-cell datasets and finds that scale ratios follow a geometric progression, refuting a developmental theory and supporting an efficient-coding explanation.

The paper identifies a three-ring shifter network in zebrafish that computes heading direction, showing convergent evolution with the Drosophila compass mechanism.

The paper analyzes mental calculation speeds in international competitions, finding rates exceeding 215 bit/s, surpassing previous estimates for high-level cognition.

The paper investigates whether grid cells encode future position by analyzing how shifting spikes in space or time affects firing field properties in mice.

This paper compares multi-scale, multi-field place codes with grid codes in simulations, finding grid codes outperform in decoding accuracy but are less robust to noise and lesions.

The paper investigates how spike afterpotentials influence burst activity in medial entorhinal cortex neurons during in-vivo behavior, finding that DAPs are associated with specific burst patterns in Layer II cells.

The paper shows anticipatory firing in head-direction neurons improves decoding accuracy by reducing temporal bias in dynamic head-direction signal estimation.

The paper shows GABA modulates action potential dynamics through a universal mechanism, confirmed by experiments and modeling in different neurons.

This paper identifies a universal sequence of dynamic transitions in neuronal excitability controlled by synaptic activity and demonstrates its implications for network synchronization and information processing.
