Can Your Eyesight Affect Your Brain?The visual system, which controls eyesight, is the largest system in the brain and can directly affect many functions of thinking, memory and cognition. We acquire information about our environment through our senses and vision plays one of the most important roles in cognition. The visual pathways of the human brain start in the retina and carry sensory information to the primary visual cortex, where it starts being processed, and then to other areas of the cerebral cortex, where complex processing and association take place.Visual processing takes up a very large fraction of the human brain-around 27%

Introduction to DopamineDopamine is one of the main neurotransmitters in the brain. It is most commonly recognized for its role in reward, motivation, and pleasure, but also plays a crucial part in modulating focus, motivation, cognitive flexibility, and emotional resilience. In addition to these creative-productive capacities and states, dopamine is one of the main regulators of motor control and coordination of body movements.[1–5]Dopaminergic substances or actions affect dopamine-related activity in the brain. The proper functioning of the dopaminergic system is of high importance for cognitive performance and emotional drive. In this article, we review the dopaminergic system, including what dopamine is,

The vagus nerve could be likened to the queen of the parasympathetic nervous system — a.k.a. the “rest and digest” — so the more we can do things that “stimulate” or activate it, like deep breathing, the more we offset the effects of the sympathetic nervous system and reduce cortisol levels.Ideally, within your autonomic nervous system, the tug of war between these two opposing mechanisms creates a “yin-yang” type of harmony marked by homeostatic balance.Unfortunately, the hectic paced, digital age we find ourselves living in causes our evolutionary biology to short-circuit by throwing our individual and collective nervous systems out of balance.It’s for this reason that

IsYour Screen Time Behavior is Impacting Your Vision? 10 Clues.“My eyes are always tired” …”My eyes hurt” …”I’m having a hard time focusing” …”My eyes feel dry and irritated” …”Things look blurry”High amounts of screen time cause the body to give us vision- and quite often posture-related feedback clues. It can also impact thinking and mood. Let’s focus on the visual system, because clues in this area are (1) a common type of feedback, and (2) an indication of visual system stress. Postural complaints, like neck stiffness and back aches, are partly to mostly a result of ergonomics, or postural discomfort, while looking at screens rather

Photo by Shaun SalmonIt all started when I was living in Taiwan, 21 years old, having just graduated from Yale with a degree in mathematics and philosophy.Of course I did what most people do with such a degree — I got a job in a bar. One day on my way to work I attempted to kick-start my motorcycle. After several unsuccessful tries I have it one final frustrated stomp with all my strength. The starting lever jammed and sprang back, severely spraining my ankle. I took a cab to work and by the time I arrived my ankle had ballooned to twice
