On the neural origin of hexadirectional fMRI modulations

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

The lattice scales of 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.

A multi-ring shifter network computes head direction in zebrafish

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

Mental calculation speeds surpass known limits for high-level cognition

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

Depolarizing afterpotentials in rodent mEC layer II neurons vary gradually across all principal cell types

The paper analyzes biophysical properties of neurons in the rodent medial entorhinal cortex, finding a continuum of depolarizing afterpotential characteristics across cell types.

Grid cells anticipate the animal's future movement

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

Burst activity plays no role for the field-to-field variability and rate remapping of grid cells.

This study investigates whether burst activity contributes to field-to-field variability and rate remapping in grid cells, finding no role for burst activity in these phenomena.

Spike afterpotentials shape the in-vivo burst activity of principal cells in medial entorhinal cortex

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.

Zebrafish use visual cues and geometric relationships to form a spatial memory

This study shows juvenile zebrafish use visual cues and geometric relationships to form spatial memory in a Y-shaped maze.

Anticipatory neural activity improves the decoding accuracy for dynamic head-direction signals

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

GABA regulates resonance and spike rate encoding via a universal mechanism that underlies the modulation of action potential generation

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