A new paper has recently been published in the International Journal of Psychophysiology, outlining work carried out by Dr Philippa Howsley and Dr Liat Levita.
The study investigated age-, gender-, and puberty-related changes in two cortical sources of spontaneous alpha during eyes-open and eyes-closed conditions in a cohort of adolescents (aged 9-23 years). Results found that prefrontal alpha was greater when eyes were open compared to when eyes were closed for 18-23 year olds, and that occipital alpha was greater for all adolescents when eyes were closed. More advanced pubertal stage predicted reduced alpha in 9-17 year old males.
This study provides an important initial step towards understanding developmental changes in the cortical sources of spontaneous alpha in the typically developing brain.
