Inside the brainstem
Reticular formation
The hippocampus is part of the limbic system and plays a crucial role in memory formation and storage. The reticular formation is located in the brainstem and is responsible for regulating wakefulness, alertness, and controlling the sleep-wake cycle.
The brain area that regulates activities controlling wakefulness or alertness of the cerebral cortex is the reticular activating system (RAS). The RAS is a network of neurons located in the brainstem that plays a key role in maintaining consciousness, attention, and arousal levels by continuously monitoring sensory inputs and sending signals to the cortex. Dysfunction in the RAS can lead to conditions like coma or excessive sleepiness.
Stimulation of the reticular formation results in increased consciousness.
Damage to the reticular formation can lead to disruptions in arousal, attention, and consciousness. Patients may experience difficulties with wakefulness, alertness, and regulating their sleep-wake cycles. This can result in issues with focus, awareness, and overall cognitive functioning.

thalamus reticular activating system
The reticular formation is located in the portion of the brainstem known as the pons. Its functions are primarily that of regulating the sleep/wake cycle, and assist in the function of discriminating incoming stimuli (which could impact the sleep/wake cycle, as well).
The reticular formation
The brain stem is where the reticular activating system is found. It is a very old system and so is a very old part of the brain common to lower life forms as well as higher life forms. See link below:
