Question

After a brain injury, Jessamyn reports many nighttime awakenings from sleep and needing several long naps

during the day. What part of the brain was likely damaged?
O Chronotype
Pituitary gland
O Suprachiasmatic nucleus
Hippocampus
O Circadian regulation center

Answer 1

The Suprachiasmatic nucleus is likely damaged after a brain injury, leading to disrupted sleep patterns.

Step-by-step explanation:

The part of the brain that was likely damaged in Jessamyn's case is the Suprachiasmatic nucleus. The suprachiasmatic nucleus (SCN) is responsible for regulating the circadian rhythm, which includes sleep-wake cycles. Damage to the SCN can lead to disrupted sleep patterns, such as frequent nighttime awakenings and excessive daytime sleepiness.
