New study makes crucial discovery about diagnosing Alzheimer’s

• Scientists have located a "mileage clock" in the brain for the first time, identifying specific "grid cells" crucial for memory and navigation.
• Research involving rats and human volunteers demonstrated that these cells "fire" in a pattern mirroring the distance travelled.
• The regularity of the grid cells' firing pattern was directly linked to the accuracy of distance estimation in both species.
• Changes in the environment, such as altering the shape of an arena, disrupted the firing patterns and led to errors in distance judgment.
• These findings offer new insights into the brain's internal navigation system and could potentially aid in the early diagnosis of Alzheimer's disease.
