    Area of Science:

    • Neuroscience
    • Cognitive Science

    Background:

    • Grid cells, discovered in 2005, are fundamental to the brain's spatial navigation system.
    • These neurons are located in the entorhinal cortex, a region implicated in Alzheimer's disease pathology.

    Purpose of the Study:

    • To investigate the communication pathways between grid cells and other neuronal types (place, border, head direction cells).
    • To elucidate the role of these interactions in spatial awareness, memory, and decision-making.
    • To explore the implications for understanding cognitive and memory loss in Alzheimer's disease.

    Main Methods:

    • The study focuses on analyzing the functional connectivity and communication dynamics between different neuronal populations involved in spatial cognition.
    • Utilizing established neuroscience research methodologies to observe and interpret neural communication patterns.
