The endocannabinoidreceptor sites where THC binds to produce its effect are found in large numbers in the brain area considered to be the seat of human consciousness, which is the
A) reticular activating system.
B) limbic system.
C) prefrontal cortex.
D) medulla-pons region.

Question

Quizplus · Accepted Answer

The prefrontal cortex is considered the seat of human consciousness, and it contains a high concentration of endocannabinoid receptor sites where THC binds to produce its effects. Therefore, option C is the best choice. The reticular activating system (A) is responsible for regulating arousal and sleep-wake transitions but does not have a significant role in consciousness. The limbic system (B) is involved in emotions and memory formation but is not considered the seat of consciousness. The medulla-pons region (D) is responsible for controlling vital functions such as heart rate, breathing, and blood pressure, but it is not related to consciousness.
