DOI: 10.1007/s12145-021-00687-2
Abstract: Susceptibility assessment of landslides over a large area depends on the basic spatial unit of mapping, usually by using grid cell or slope unit. Both units are used in this study for the assessment of… read more here.

DOI: 10.1016/j.cobeha.2017.08.012
Abstract: It has been proposed that path integration in mammals is performed by the convergence of internally generated speed and directional inputs onto grid cells. Although this hypothesis has been supported by the discovery that head… read more here.

DOI: 10.1016/j.cub.2018.02.038
Abstract: Summary A progressive loss of navigational abilities in old age has been observed in numerous studies, but we have only limited understanding of the neural mechanisms underlying this decline [1]. A central component of the… read more here.

DOI: 10.1016/j.neuron.2016.12.023
Abstract: The earliest stages of Alzheimer's disease (AD) are characterized by the formation of mature tangles in the entorhinal cortex and disorientation and confusion when navigating familiar places. The medial entorhinal cortex (MEC) contains specialized neurons… read more here.

DOI: 10.1038/s41598-021-03124-y
Abstract: The regular equilateral triangular periodic firing pattern of grid cells in the entorhinal cortex is considered a regular metric for the spatial world, and the grid-like representation correlates with hexadirectional modulation of theta (4–8 Hz)… read more here.
