Memory Helps Us Evaluate Situations on the Fly, Not Just Recall the Past

The findings shed light on how the hippocampus contributes to memory and exploration, potentially leading to therapies that restore hippocampal function, which is impacted in memory-related aging and neurodegenerative diseases such as dementia, the study authors said.
In the study, scientists monitored participants' brain activity and tracked their eye movements while looking at different complex pictures. The scientists discovered that as we visually scan our environment and absorb new information, our hippocampus becomes activated, using short-term memory to better process new visual information to help us rapidly reevaluate situations.
[...] "At any given moment, your brain rapidly initiates eye movements that you are typically unaware of," said corresponding author James Kragel, a postdoctoral research fellow at Northwestern University Feinberg School of Medicine. "Our findings suggest the hippocampus uses memory to inform where your eyes look, thereby priming the visual system to learn and reevaluate our environment on the fly.
