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.

The Reticular Activating System (RAS) is a bundle of nerves that sits in your brainstem. And its job is to regulate behavioural arousal, consciousness and motivation. What that means is, the RAS is able to control what incoming information (stimulus) you’re aware of, so that you’ll be motivated to behave in a certain way. But what does that ...
Jul 24, 2023 · The RAS is a component of the reticular formation, found in the anterior-most segment of the brainstem. The reticular formation receives input from the spinal cord, sensory pathways, thalamus, and cortex and has efferent connections throughout the nervous system.
The reticular activating system (RAS) is not an amorphous region but distinct nuclei with specific membrane properties that dictate their firing during waking and sleep.
Jan 1, 2018 · The reticular activating system (RAS) denotes that part of the brainstem reticular formation that performs a crucial role in maintaining behavioral arousal, consciousness, and motivation.

RAS refers to a bundle of nerves located on the brain stem. Much like most other parts of the brain, the RAS is responsible for a host of tasks; sleep-wake transition, wakefulness, and behaviour. But, in the context we are looking at today, the RAS also tunes our attention, regulates behaviour, and drives motivation.
