What outcome is associated with damage to the lateral hypothalamic nuclei?
Understand the Problem
The question is asking about the physiological effects that occur when the lateral hypothalamic nuclei are damaged, specifically focusing on the outcomes related to energy, appetite, pain sensitivity, and temperature regulation.
Answer
Narcolepsy with symptoms like hypersomnolence, sleep-wake fragmentation, and cataplexy.
Damage to the lateral hypothalamic nuclei can lead to narcolepsy, characterized by hypersomnolence, sleep-wake fragmentation, increased REM sleep, and cataplexy.
Answer for screen readers
Damage to the lateral hypothalamic nuclei can lead to narcolepsy, characterized by hypersomnolence, sleep-wake fragmentation, increased REM sleep, and cataplexy.
More Information
The lateral hypothalamic area is critical in controlling functions such as arousal and feeding behaviors. Damage here impacts neural cells that produce orexins, leading to conditions like narcolepsy.
Tips
Common mistakes include confusing the effects of damage to the lateral hypothalamus with outcomes of damage to other areas of the hypothalamus, such as the ventromedial hypothalamus.
