Benefits of Focusing Visual Attention on a Small Region of Space
56:15 - 1:06:39 (10:23)
Focusing visual attention on a small region of space for at least 60 seconds increases visual acuity, brain activity and enhances our ability to gather information from that location, leading to the release of acetylcholine and epinephrine in the brain for plasticity.

The acetylcholine system, responsible for focus and available through both pharmacology and behavioral practices, can be enhanced by developing behavioral practices centered around visual focus.

Summary
The acetylcholine system, responsible for focus and available through both pharmacology and behavioral practices, can be enhanced by developing behavioral practices centered around visual focus. Those on Adderall may experience increased focus due to autonomic nervous system regulation towards parasympathetic function.

Summary
Focusing on a small window of our screen for 60 to 120 seconds stimulates an increase in activity in several brain areas that are crucial for acquiring information from that location. This technique can help increase visual acuity and the brain's ability to focus, which is beneficial for tasks such as reading and listening.

The neurons in our brainstem responsible for making us feel alert also control our eyelids, and as we get tired, our blinking increases.

Summary
The neurons in our brainstem responsible for making us feel alert also control our eyelids, and as we get tired, our blinking increases. Practicing blinking less and focusing our visual attention on a smaller region of space can improve alertness and reduce blinking.
