The Reticular Activating System (RAS) of the brain stem is considered as one of the most important systems which facilitates the functioning of sensation and attention. This is made up of a net-like bundle of neurons that run through the hind-brain, mid-brain and a part of the fore-brain called the hypothalamus.

Jun 22, 2017 · The Reticular Activating System (RAS) is a bundle of nerves at our brainstem that filters out unnecessary information so the important stuff gets through. The RAS is the reason you learn a...

Waking and the reticular activating system (RAS) as described in this book has much wider scientific and societal implications than at first sight. The RAS mediates preconscious awareness, which represents the context of our lives, and is responsible for our survival.

Sep 27, 2017 · The reticular activating system (RAS) consists of neuronal networks originating in brainstem regions that project upward to the subthalamic nucleus and from there to many cortical and subcortical brain structures as indicated by arrows.

How can your subconscious mind help your community? Learn about RAS (Reticular Activating System) and how it can help focus you on the positive in your community.
