A Relevant Analysis of Motor-Related Alpha Frequency in Infant Patients

Dr. Atish Nishad

This rhythm arises from resting sensorimotor activity and has a defined frequency range of 8–13 Hz, the same frequency as the alpha band. Mu rhythms are cortical oscillations that can be recorded from the scalp overlying the primary sensorimotor cortex using electroencephalography (EEG) and magneto encephalography (MEG). To date, alpha rhythm research has involved subjects ranging from infants to adolescents to the elderly. In addition, these subjects included not only healthy people, but also patients suffering from various neurological and psychiatric disorders. However, few studies have addressed the effects of alpha rhythm on aging and there is no review of the literature on this subject. Focusing on age-related changes in mu rhythm, it is important to examine the details of the features of alpha rhythm activity in the elderly compared with young. Through a comprehensive review, older adults compared with younger individuals showed changes in alpha activity, increased event-related desynchronization (ERD), earlier onset and later termination, and symmetrical we found that it showed an ERD pattern, and increased cortical recruitment. Cells revealed areas with significantly reduced beta-event-associated desynchronization (ERS). It was also found that the alpha rhythm pattern of behavioral observation changed with age. Future research is needed to study not only the localization of the elderly, but also the network of alpha rhythms.
