Basic Scientific Research


Research in the laboratory focuses on the understanding of the neurobiology of stress-related disorders, particularly Post-traumatic stress disorder and stress-induced depression.

We examine the effects of stressful experiences early and later in life on cognitive and emotional abilities in adulthood. We attempt to differentiate between the effects of very early and juvenile stress, acute and chronic stress and between controllable and uncontrollable stress.

In our lab, we have developed several behavioral models of mood and anxiety disorders and are currently studying their electrophysiological and biochemical consequences.

We study the role of emotional activation in memory formation and assess the interactions between the hippocampus, amygdala, prefrontal and entorhinal cortex, when learning under different levels of emotional activation. Both in vivo field potential recordings and measurements of signal transduction cascade activation are utilized in order to map the patterns of activation of these limbic regions.



Some of our current projects:   

  • A crosstalk between neuropathic pain and depression (emotional pain) – establishing a novel drug development platform
  •  SSRIs effects in an animal model of PTSD
  •  Modeling of complex PTSD-like behaviors using individual differences in rats
  • The role of Ventral Hippocampus GAD65 in anxiolytic behavior 
  • Periaqueductal gray modulation of the basolateral amygdala and the nucleus  accumbens under controllable and uncontrollable stressful conditions
  • Putative mediators of vulnerability and resilience in an animal model of PTSD, with specific interest in GABAergic factors and neuropeptides
  • The effects of juvenile stress on the course of inflammation 
  • Behavioral Profiling as a translational approach for dissecting molecular correlates in ananimal model for PTSD.
