Brain areas that control alertness or sensitivity, independent of what the person is alert or sensitive to, include the __________.
A) hippocampus
B) reticular activating system
C) frontal cortex
D) medulla
Reticular Activating System
A network of neurons located in the brainstem that regulates wakefulness and sleep-wake transitions.
Alertness
The state of active attention and readiness to respond to stimuli, often considered a key component of consciousness.
Brain Areas
Specific regions of the brain that have distinct functions, such as the frontal lobes for decision making and the hippocampus for memory.
- Recognize specific brain regions and their associated tasks, especially in the context of perceptual processing and memory retention.

Final Answer :
B
Explanation :
The reticular activating system (RAS) is a network of neurons located in the brainstem that plays a key role in regulating arousal, alertness, and attention. It filters out irrelevant sensory input and promotes wakefulness and selective attention to important stimuli. The other brain areas listed may play a role in cognition, memory, emotion, or autonomic functions, but they are not primarily responsible for controlling alertness or sensitivity.

- Recognize specific brain regions and their associated tasks, especially in the context of perceptual processing and memory retention.
