Remember the saying “use it or lose it” ? The brain cells that receive stimulation through our senses, experiences, and activitie continue to develop and improve. Cells that do not receive stimulation tend to be lost through pruning.
Our early years are the most active years of cell development. But complexity of cell development can continue throughout our lives.
In recent years we have been seeing very different areas of brain cell complexity being developed.* The extreme amount of time our children and youth experience from excessive stimulation first with television and now cell phones and computers activates specific areas.
Including when they’re multitasking, 8- to 18-year-olds consume an average of 7 hours and
11 minutes of screen media per day—an increase of 2.5 hours in just 10 years.(1)
For older children and adolescents, excessive screen time is linked to increased psychological difficulties that include hyperactivity, emotional and conduct problems, difficulties with peers (2) and poor school performance.(3)
While complexity develops in one area, we need to be aware that there may be loss of cell structure in areas of neglect-pruning is taking place.
Balance Activities and Experiences
Increase variety of activity and experience for maximum learning:
Providing experiences to nourish all the senses creates maximum brain capacity. Conversation, observation, active movement, quiet time, contemplation, and creative opportunity will maximize brain function.
