Abstract The hippocampus undergoes substantial structural remodeling across the lifespan, yet how its resident immune cells, microglia, reorganize during development and aging remains poorly understood in primates. We quantified microglial density and spatial organization across hippocampal subfields in 15 female rhesus macaques spanning late gestation (gestational day 140) to advanced age (32.4 years) using tissue from the MacBrain Resource Center.

When rubber meets the road The longer I spend time outdoors, the more comfortable I become. I came to a point where I felt confident. I’m assured that I know everything I need to know about backpacking outdoors. Not so fast. Although I did countless hours of research about this trail, nothing beats the experience itself. With that being said, I would like to share with you how the trail humbled me.

How subtle or obvious it is, it really defines my personality and identity on trail. Flow state hiking There are instances in my studies and in my desk job that I feel so absorbed in what I do. It’s where productivity is at its highest. I lose the sense of time.
