Penelitian baru  berhasil mengetahui bagaimana ingatan  jangka panjang  bisa  terbentuk. Peneliti berharap penemuan itu bisa  membantu ilmuwan  mengembangkan cara perawatan berhubungan dengan  ingatan.
Studi  itu dilakukan oleh peneliti di Wake Forest University School of   Medicine.
"Meskipun sudah diketahui ingatan terbentuk dari  pengalaman berulang,  tapi tidak banyak yang diketahui bagaimana ingatan  terbentuk hanya  dengan satu paparan," kata Ashok Hegde Ph.D, ketua  penelitian itu.
Ilmuwan sudah tahu orang cenderung mengingat  secara tajam peristiwa yang  membahagiakan maupun yang sedih karena  hubungan emosional. Emosi yang  ekstrim akan melepas zat kimia ke otak  disebut norepinephrine yang  berhubungan dengan adrenaline. Zat  norepinephrine ini dalam satu hal  membuat ingatan lebih panjang.
Sebagai  contoh, orang akan cepat ingat peristiwa serangan teroris.  Karena  peristiwa itu merupakan tragedi.
Namun studi yang dilakukan oleh  Hegde dan koleganya mencari tahu  bagaimaan kerja norepinephrine. Tim  mencari tahu apakah zat itu membantu  tikus betina mengingat bau  pasangan jantannya hanya dalam satu kali  kawin.
Studi itu  mendapati, sirkuit syaraf mengaktifkan olfactory bulb, tempat  ingatan  bau jantannya disimpan. Peneliti mendapati norepinephrine  dilepas saat  tikus kawin, mengaktifkan enzim yang disebut Protein Kinase  C (PKC)  terutama alpha isoform PKC di olfactory bulb. Enzim PKC ada di  otak  berbagai mamalia termasuk manusia.
"Kenyataan PKC-alpha  diaktifkan saat keluarnya norepinephrine adalah  penemuan penting. Itu  menjelaskan bagaimana terbentuknya ingatan yang  kuat,” kata Hegde.
