Abstract The cerebral cortex is organized along a dominant sensorimotor-to-association (S–A) axis, anchored by modality-specific primary sensorimotor areas at one end and transmodal association areas forming distributed networks that support abstract cognition at the other1,2,3,4,5,6,7,8,9,10,11. The developmental mechanisms shaping this axis remain unclear9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24.

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.

Abstract Liquid interfaces play central roles in biological and physicochemical processes. Sum-frequency-generation (SFG) spectroscopy is intrinsically interface-specific, but the insight gained from SFG spectra into molecular interfacial structure has been limited since spectral analysis is usually done within the electric-dipole approximation, neglecting higher-order multipole contributions.
