2 Pantangan Belajar di Malam Sebelum Ujian

1. Jangan mengorbankan waktu tidur. Sebuah penelitian yang dilakukan pada tikus-tikus lab menunjukkan bahwa ketika mereka tidur, bagian otak yang terkait dengan memori ternyata masih aktif dan mengulang (dalam pikiran) hal-hal yang telah dipelajari sewaktu masih bangun tadi. Jadi sebenarnya anda belajar juga selama tidur itu.

2. Kalau bisa, belajarlah sebelum hari gelap. Ini terkait dengan melatonin, yaitu hormon yang berperan dalam pengaturan jam biologis kita. Dalam percobaan yang dilakukan terhadap ikan zebra, ikan-ikan yang dilatih di siang hari (ketika hormon melatonin sedang rendah) bisa mengingat latihannya dengan lebih baik dibanding ikan yang dilatih di malam hari.

Scientists are finding new evidence that a good night’s rest plays a crucial role in cementing memories formed during the day.

One new study has identified a brain region involved, along with the hippocampus, in creating memories of the day’s activities during sleep. Another study suggests melatonin, a hormone involved in regulating our day-night cycle, or “circadian rhythm,” acts to suppress the formation of new memories as bedtime nears, perhaps in an effort to give memories made earlier in the day a chance to be prepared for long-term storage.

So does that mean learning is best done during the day and not at night?

Maybe, Roman said, but he points out that the human memory system is much more complex than that of the zebrafish, and while melatonin should inhibit memory formation at night in us, its effects will be buffered by other hormones and other brain components.
