| dbo:abstract | Postprandial somnolence (colloquially known as food coma, after-dinner dip, and postprandial sleep, or by the African-American Vernacular English term the itis) is a normal state of drowsiness or lassitude following a meal. Postprandial somnolence has two components: a general state of low energy related to activation of the parasympathetic nervous system in response to mass in the gastrointestinal tract, and a specific state of sleepiness. While there are numerous theories surrounding this behavior, such as decreased blood flow to the brain, neurohormonal modulation of sleep through digestive coupled signaling, or vagal stimulation, very few have been explicitly tested. To date, human studies have loosely examined the behavioral characteristics of postprandial sleep, demonstrating potential shifts in EEG spectra and self-reported sleepiness. To date, the only clear animal models for examining the genetic and neuronal basis for this behavior are the fruit fly, the mouse, and the nematode Caenorhabditis elegans.

(sv) 餐後嗜睡（英語：Postprandial somnolence）也俗稱為食物昏迷（英語：food coma）或飯氣攻心，是指用餐後出現昏睡或是疲倦的正常情形。餐後嗜睡有二個組成內容：用餐後因為消化道中的食物活化副交感神经所造成的低活力狀態，以及特定狀態下的昏睡或是疲倦。有關餐後嗜睡有許多的理論，例如腦部的血流量下降，一些和消化耦合的訊號造成神經激素調節到容易睡眠的狀態，或是迷走神經的刺激，不過這些理論都還沒有具體的進行實驗。到目前為止已有人體實驗大略的檢查餐後嗜睡時的行為特性，表現方式是腦電圖頻譜的潛在相位移，以及受試者自我報告是否有想睡的情形。目前為止只有針對果蠅及老鼠的此一行為，清楚地檢驗遺傳及神經元基礎，也是唯一的動物模型。 (zh) |
