The mental state characterized by a lack of arousal, even in response to pain, is comatose. In a comatose state, an individual is unresponsive and cannot be awakened, demonstrating no awareness of their surroundings or any stimuli, including painful stimuli. This profound level of unresponsiveness is essential for medical professionals to recognize as it has critical implications for the patient's prognosis and the necessary care interventions.

In contrast, drowsiness indicates a state where an individual may be somewhat aware and can be aroused with sufficient stimulation. Depression can lead to decreased energy and motivation, but it doesn't typically eradicate responsiveness to pain. Obtunded refers to a state that involves diminished alertness and may include reduced responses, but individuals in this state can still respond to some stimuli, including pain, albeit less effectively than in a fully alert state. Thus, the distinct lack of arousal and awareness in a comatose state aligns accurately with the description given in the question.
