<prompt> Utafiti uliofanywa na Zhang na wenzake kuhusu ishara za Ras na Rap katika plastiki ya synaptic: Zhang L, Zhang P, Wang H, Zhang Yu, Zhang Y, Zhang M, Xiao J, Crespo, Hell, Lin L, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian, Hu Jian.  <response>: Utafiti wa Ras na Rap, uliofanywa na Zhang na wenzake, unachunguza jukumu la Ras na Rap katika synaptic plasticity, ambayo ni muhimu kwa kujifunza na kumbukumbu. watafiti walitumia mbinu za electrophysiological na imaging kuchunguza jinsi Ras na Rap signaling njia kudhibiti synaptic plasticity katika tofauti subcellular microdomains. wao kupatikana kwamba Ras signaling modulates nguvu ya synaptic katika postsynaptic tovuti, wakati Rap signaling kudhibiti nguvu synaptic katika presynaptic tovuti.
