Topic: auditory stimulation

Background: Age-related sleep architecture alterations include fewer N2 sleep spindles, shorter N3 duration, and Slow Waves. This is linked to age-related decline in cognition. Auditory stimulation (AS) improves sleep oscillations. Aim: This study examines how open-loop AS impacts spindles and SW in young (YNG) and older (OLD) individuals during N2 and N3. Methods: A nap polysomnography was conducted on two healthy adult groups: YNG (n=8, 19–34 years) and OLD (n=6, 50–65 years). In N2 and N3 stages, a 20s AS was given, with 2s of 13.75 Hz modulated pink noise, 8s of constant pink noise, and 10

Neuronal oscillations can be used to understand brain plasticity phenomena during trauma. The oscillations of local field potentials (LFP) represent the phasing of the membrane potentials of different types of neurons at both the cortical and subcortical levels. In this project, we have studied the plasticity process that occurs in the primary visual cortex following monocular enucleation in mice using LFP recordings. To elicit a response in V1, animals are subjected to protocols of visual, auditory, and somatosensory stimulation while the electrode remains in the same location (figure). We ha
