- Disruption of Pavlovian contextual conditioning by excitotoxic lesions of the nucleus accumbens coreLiat Levita
Department of Experimental Psychology, University of Cambridge, United Kingdom
Behav Neurosci 116:539-52. 2002..These results suggest that during acquisition, processes independent of the NAcc core mediate contextual conditioned freezing, but that the NAcc is implicated in the retention of this aversive memory...
- Subtypes of substance P receptor immunoreactive interneurons in the rat basolateral amygdalaLiat Levita
Department of Psychiatry and Behavioral Sciences, Emory University, Woodruff Memorial Building, 1639 Pierce Drive, Rm 4000, Atlanta, GA 30322, USA
Brain Res 981:41-51. 2003..Consequently, these results support the use of SP-saporin lesions as a useful technique to study the role of NPY-IR interneurons in the BLA...
- Nucleus accumbens dopamine and learned fear revisited: a review and some new findingsLiat Levita
Department of Experimental Psychology, University of Cambridge, Downing Street, CB2 3EB, Cambridge, UK
Behav Brain Res 137:115-27. 2002..Hence, rather than discount an involvement of NAcc DA in affective processes, we propose that functionally dissociable sub-regions of the NAcc may contribute to different aspects of Pavlovian aversive learning...
- Sulpiride alleviates the attentional impairments of rats with medial prefrontal cortex lesionsFilippo Passetti
Department of Experimental Psychology, University of Cambridge, Downing Street, Cambridge CB2 3EB, UK
Behav Brain Res 138:59-69. 2003..These results extend previous findings of attentional impairments in rats with mPFC lesions and are compatible with recent hypotheses concerning the role of dopaminergic dysregulation in the pathogenesis of schizophrenia...
