The role of the anterior thalamic nuclei (ATN) has been proven in different learning and memory tasks.The ATN consist of three main subnuclei, the anterodorsal (AD), anteroventral (AV) and anteromedial (AM), whichhave different biological characteristics such as distinct circuitry, cell population and neurotransmitter content.The role of ATN subnuclei in learning and memory has been shown in several studies. However, their probablerole in different phases of memory including acquisition, consolidation and retrieval are not still well-known.For this purpose, the effect of reversible inactivation of each ATN subnucleus on different memory phases intwo behavioral tasks including passive avoidance (PA) and Morris water maze (MWM) was studied. Wister malerats were bilaterally implanted with cannulas above the AD, AV or AM subnucleus in separate experimentalgroups in order to inject lidocaine (4
