Train resting neural networks, responsible child's for lack of attention


Train resting neural networks, responsible child's for lack of attention

Various theories of the mind divide the intrinsic activity of brain into multiple low frequency or resting state neural network as DMN and relatively high frequency states such as TPN and TNN (task positive/negative network). DMN or default mode network is active when the child is at complete rest. Low frequency states retains large amount of information, which helps child to perform tasks in active states. In disordered child the change of state from rest state to active state to perform tasks, deactivates certain neural networks. This results into child not being able to perform amazingly in active states. Temple bells, meditation, recitation of Vedic mantras or hymns are low frequency activities. Such low frequency  activities train default mode network. There is a exponential development of DMN states in very young children. This cease to develop with adults or adolescent children, but these low frequency states could developed by training. Wandering mind is thought to occur due to the ability of DMN to continue to process self-referential material at variable levels which is related the degree of attention required to tend to tasks in external environment. A person who is deeply involved in a task has significant attenuation of DMN with minimal wandering thoughts, whereas a person participating passively in a task has an active DMN giving way to the emergence of activities such as "day dreaming", "spacing out", and opportunity to multi-task. Temple bells, meditation, recitation of Vedic mantras or hymns might improves attention deficit/hyperactivity disorder (ADHD) syndromes in child by indirect training of DMN areas.
