Institute of Psychiatric Research, Department of Psychiatry, Indiana University School of Medicine, Indianapolis, Indiana 46202, USA
J Neurosci 28:893-903. 2008..These studies suggest one putative physiologic mechanism underlying stress resilience and could identify novel targets for development of therapies that can augment the ability to cope with stress...

- The role of neuropeptide Y in the amygdala on corticotropin-releasing factor receptor-mediated behavioral stress responses in the ratTammy J Sajdyk
Department of Psychiatry, Indiana University School of Medicine, Institute of Psychiatric Research, Indianapolis, IN 46202, USA
Stress 9:21-8. 2006..These results provide further support that an interaction between NPY and CRF within the BLA may be critical for maintaining a normal homeostatic emotional state...
- From anxiety to autism: spectrum of abnormal social behaviors modeled by progressive disruption of inhibitory neuronal function in the basolateral amygdala in Wistar ratsWilliam A Truitt
Department of Psychiatry, Indiana University School of Medicine, 1111 West 10th Street, Indianapolis, IN 4620, USA
Psychopharmacology (Berl) 191:107-18. 2007..Social behaviors are disrupted in several psychiatric disorders. The amygdala is a key brain region involved in social behaviors, and amygdala pathology has been implicated in disease states ranging from social anxiety disorder to autism...

Department of Psychiatry, Institute of Psychiatric Research, Indiana University School of Medicine, Indianapolis, Indiana 46202, USA
J Neurosci 26:9205-15. 2006..Thus, these results implicate A-II pathways and the A-II receptors in the hypothalamus as putative substrates for sodium lactate-induced panic-like responses in vulnerable subjects...

Department of Psychiatry, Indiana University Medical Center, Indianapolis, Indiana 46202, USA
Ann N Y Acad Sci 985:308-25. 2003..These results suggest that the BLA has a significant role in regulating anxiety, autonomic responses, and the development of anxiety disorders...

Department of Anatomy and Cell Biology, Indiana University School of Medicine, Indianapolis, IN, United States
Prog Neuropsychopharmacol Biol Psychiatry 44:248-56. 2013..Overall these results are the first to implicate A-II and AT1rs as putative neurotransmitter-receptors in NaLac induced panic-like responses in UCN/BLA-primed rats...
