Barasa yana aiki azaman babban abin damuwa na tsarin juyayi na tsakiya, amma kuma yana shafar wasu takamaiman wuraren kwakwalwa fiye da sauran. An danganta lalacewar ƙwaƙwalwar ajiya da barasa ke haifar da rushewar aikin hippocampal -musamman yana shafar gamma-Aminobutyric acid (GABA) da N-methyl-D-aspartate (NMDA) neurotransmission wanda ke haifar da mummunan tasiri na dogon lokaci (LTP).  Tushen kwayoyin halitta na LTP yana da alaƙa da koyo da ƙwaƙwalwa.  Musamman, lalacewa ga sel na hippocampal CA1 yana haifar da mummunar tasiri akan samuwar ƙwaƙwalwar ajiya,  kuma wannan rushewar an danganta shi da matakan dogaro da kashi na yawan barasa.  A mafi girma allurai, barasa yana hana aikin neuronal a cikin duka CA1 da CA3 pyramidal cell layers na hippocampus .
