    • Análise da influência do sono na expressão da proteína quinase M zeta e na memória de ratos 

      Barros, Luísa Mendes Amando de [UNIFESP] (Universidade Federal de São Paulo (UNIFESP), 2015-01-09)
      Memory comprises acquisition, consolidation and retrieval of information. After consolidation memories must be maintained, a process that seems to be mediated by an atypical isoform of protein kinase C (PKC), the protein ...
