Temporal instability weakens entorhinal grid-like coding in older adults

This study shows that unstable hexadirectional signals in the entorhinal cortex of older adults correlate with poorer memory and reduced signal strength, suggesting grid-like coding instability rather than absence.

Entorhinal grid coding as a functional link between tau accumulation and episodic memory in human aging

The paper investigates how tau accumulation in the entorhinal cortex affects episodic memory by analyzing grid-cell-like signals in older adults using MRI and tau PET.

rTCT: Rodent Triangle Completion Task to facilitate translational study of path integration

This paper develops a rodent version of the Triangle Completion Task to improve cross-species comparability in path integration studies.

Altered coding of environmental boundaries in human aging: an fMRI study

This study investigates how aging affects the use and neural representation of environmental boundary information during spatial memory tasks using fMRI.

Path integration impairments reveal early cognitive changes in Subjective Cognitive Decline

This study identifies path integration impairments in individuals with subjective cognitive decline, suggesting memory leak as an early marker of neurodegeneration related to Alzheimer's disease.

The role of memory and perspective shifts in systematic biases during object location estimation

The paper investigates systematic biases in object location estimation during perspective shifts, finding participants consistently overestimate object positions in the same direction as the shift.
