Landmark-Based Updating of the Head Direction System by Retrosplenial Cortex: A Computational Model
Frontiers in Cellular Neuroscience, 2018 Maintaining a sense of direction is fundamental to navigation, and is achieved in the brain by a network of head direction (HD) cells, which update their signal using stable environmental landmarks.

Current‐Driven Chirality Detection of Magnetic Textures in Cylindrical Nanowires
Advanced Functional Materials, EarlyView.Current‐assisted anisotropic magnetoresistance measurements in individual Ni/Au cylindrical nanowires enable detection of vortex chirality near Au segments and selective magnetic reversal in defined wire sections at magnetic fields lower than the propagation field. This approach provides a simple, cost‐effective, and non‐invasive method for probing and

Recurrent circuits within medial entorhinal cortex superficial layers support grid cell firing
Nature Communications, 2018 Medial entorhinal cortex (mEC) neurons encode various navigation parameters such as speed, head direction, as well as grid cells. Here, the authors demonstrate that brief disruption of the local activity in mEC specifically affects grid cell tuning.
