    Irit Akirav
    Department of Neurobiology, Weizmann Institute of Science, Rehovot, Israel
    Neuropsychopharmacology 32:542-50. 2007
    ..These findings could bear relevance to the potential involvement of extinction abnormalities in behavioral disorders, and their amelioration...

    Irit Akirav
    Department of Neurobiology, Weizmann Institute of Science, Rehovot 76100, Israel
    Eur J Neurosci 23:758-64. 2006
    ..The involvement of GABA(A) receptors in fear extinction in the prefrontal cortex and amygdala is of particular interest, because of the role of these areas in emotional processes, and the role of the GABA(A) receptors in anxiety states...
  3. ncbi request reprint Ventromedial prefrontal cortex is obligatory for consolidation and reconsolidation of object recognition memory
    Irit Akirav
    Department of Neurobiology, Weizmann Institute of Science, Rehovot, Israel
    Cereb Cortex 16:1759-65. 2006
    ..These results indicate that both protein synthesis and NMDA receptors are required for consolidation and reconsolidation of recognition memory in the vmPFC...

    Irit Akirav
    Laboratory of Behavioral Neuroscience, Department of Psychology, University of Haifa, Haifa 31905, Israel
    J Neurosci 22:9912-21. 2002
    ..Possibly, at the onset of an emotional event the stress hormones permissively mediate plasticity. However, their prolonged presence in the system may suppress the cognitive response to stress...
  5. pmc A facilitative role for corticosterone in the acquisition of a spatial task under moderate stress
    Irit Akirav
    Department of Psychology and The Brain and Behavior Research Center, University of Haifa, Haifa 31905, Israel
    Learn Mem 11:188-95. 2004
    ..These two mirror experiments of corticosterone blockade and enhancement strongly suggest that corticosterone is instrumental in the acquisition and retention of the spatial learning task...

    Irit Akirav
    Department of Neurobiology and Ethology, The Brain and Behavior Research Center, University of Haifa, Haifa 31905, Israel
    Learn Mem 13:254-8. 2006
    ..Anisomycin microinfusion into vmPFC had no effect on CTA acquisition and by itself did not induce CTA. These findings show the necessary role functional protein synthesis is playing in the vmPFC during the learning of CTA extinction...
