Adults with Down syndrome display altered entrainment of occipital cortical neurons.

ABSTRACT: Down syndrome is commonly associated with a trisomy of chromosome 21 that often presents an accelerated aging profile and higher probability of developing Alzheimer's disease-like symptoms at a relatively early age. However, the physiological changes that may contribute to such symptoms remain poorly understood. To begin to address this knowledge gap, we used magnetoencephalographic neurophysiological imaging to assess the entrainment of occipital cortical neurons to a 15 Hz visual stimulus in a cohort of adults with DS without a dementia diagnosis (N = 26; Age = 27.65 ± 9.55 years) and a demographically matched cohort of neurotypical controls (N = 22; Age = 30.81 ± 8.02 years). Our results indicated that adults with Down syndrome exhibit substantially weaker entrainment of t
