Learning at night; Hassot:

One who is awake and learning at night, must say (at Hassot) Shema She'al HaMita, and then Birkhot Hashahar. However, one does not recite Birkhot HaTorah at this time, rather when the days appears. However, if one was sleeping and then arose at Hassot, he must recite all the Berakhot HaShahar, and then say Tikkun Hassot (Dibre Shalom, Siman 14).

All 18 Berakhot one must recite them, and even if he does fuflfill their actions (Nahar Shalom 20b).
