This YouTube video discusses the potential harmful effects of screen time on the frontal cortex. It points to research that suggests that screen time can lead to problems like ADHD, Alzheimer's disease, and premature graying of hair. The video also provides tips on how to reduce screen time and improve cognitive function.

  • 00:00:00 This homeschool mom shares her research on the effects of screen time on the frontal cortex, which she believes is causing problems for children. She discusses the three books she read on the subject, which she believes provide valuable information on the negative effects of video gaming on children's brains.
  • 00:05:00 This woman explains how screen time has affected her behavior and personality. She says that the changes started happening around three to four years ago, when she and her husband started looking for land to live self-sustainably. She used to wake up early to go look for land, but started to get tired and slip out for coffee. Eventually, she became addicted to coffee and junk food, and her husband started to get tired too. She shares how all this changed when they moved to their current land and started living a self-sustainable and self-reliant life.
  • 00:10:00 The video discusses how the prefrontal cortex, located in the frontal lobe, is important for various cognitive functions, such as rational thinking, self-control, and focus. It also discusses how damage to the prefrontal cortex can lead to various behavioral problems, such as addiction, depression, and impulsiveness. The video provides tips on how to improve cognitive function and reduce behavioral problems through a combination of lifestyle changes and brain training exercises.
  • 00:15:00 The prefrontal cortex is responsible for many higher cognitive functions, including decision making, focus, and self-control. Damage to this area can lead to problems such as procrastination, memory loss, and dementia. The pre-motorchotics and the primary motor cortex are both located in the pre-frontal cortex. The pre-motorchotics helps in self-initiated movements, while the primary motor cortex generates signals to direct the movement of body parts. The ventral lateral prefrontal cortex is responsible for motor inhibition, which reflects reorienting and attention shifting based on situation. The lateral anterior prefrontal cortex helps in higher cognitive functions, such as task management and the execution capability. The dorsolateral prefrontal cortex helps in rational thinking, self-control, and focus. It also gives the sense of time. The prefrontal cortex is most important during the developmental stage from age 25 to 26. Teens who consume lots of junk food are likely to have impaired prefrontal cortex function.
  • 00:20:00 According to this YouTube video, excessive screen time can damage the frontal cortex, which can lead to addiction and mental illness. The video also mentions research that indicates that screen time can deactivate the dorsol lateral prefrontal cortex, which is the part of the brain responsible for decision-making.
  • 00:25:00 The video discusses the effects of dopamine, serotonin, and other neurotransmitters on the brain, and how low levels or high levels of these chemicals can lead to various health problems. The video also discusses how a "Trader or Investor's brain is pretty much working like a gambler," all of which is due to reduced activity in an area of the brain associated with pain and negative emotions. These people will have no empathy in the long run, and because they lose the ability to control their impulses, the combination of these two attributes will push them toward immorality and disgraceful environment.
  • 00:30:00 The mother of a homeschooled child points out that too much screen time can harm the frontal cortex, leading to problems like ADHD, Alzheimer's disease, premature graying of hair, low blood pressure, and fibromyalgia. She encourages viewers to have faith in God and in their free will, and to avoid screen time that is too high in chemicals.
