- A publication in Nature Neuroscience by Cyril Herry's team
Internally generated 4 hz oscillations synchronize prefrontal-amygdala neuronal circuits during fear behaviour. Fear response to traumatic or threatening situations helps us evade or escape danger. At the same time fear response is learned in the form of association between stimulus or situation and the presence of a stressor (e.g. physical danger). This association is very powerful and leaves a memory trace that persists for years after a single experience, generating profound structural and functional changes in the brain that can potentially develop into post-traumatic stress and other anxiety-related disorders.[ read more ]Share on

- Neuronal Circuits for Fear Expression and Recovery: Recent Advances and Potential Therapeutic Strategies
In this publication in Biological Psychiatry, Cyril Dejean and Cyril Herry review the functional role of distinct neuronal structures involved in the expression and recovery of conditioned fear responses and detail the non-canonical neuronal circuits recently identified to play a key role in fear expression. The identification of neuronal circuits dedicated to fear expression may promote the development of new therapeutical strategies for anxiety disorders and related psychiatric conditions.[ read more ]Share on
- CocAddict Consortium meeting in Bordeaux
Members of the European ERA-NET NEURON (Network of EUROpean funding for Neuroscience research). COCADDICT met in Bordeaux on July, 7th and 8th 2015, in the premises of Magendie Neurocenter. Specialized in cocaine addiction mechanisms, this network members develop preclinical and clinical research projects on neural mechanisms involved in cocaine addiction process. Coming from Canada and Germany, the neuroimaging and electrophysiology experts of this consortium came in Bordeaux to share their results with their French partners and promote the development of scientific collaborations.[ read more ]Share on

- A second publication for Optopath in Neuropsychopharmacology
Cocaine seeking: The dual role of the prelimbic cortex in High frequency users. Coupling cocaine intravenous self-administration with optogenetic, Dr Deroche-Gamonet in collaboration with Dr Herry reveals that high frequency cocaine intake promotes a PL-dependent control of cocaine seeking, with the PL exerting a facilitatory effect on cocaine-induced resinstatement and an inhibitory effect on cocaine self-administration. Individual differences in cocaine-induced PL activation might be a source of vulnerability for poorly controlled cocaine-induced seeking and/or cocaine intake.[ read more ]Share on
- First publication for OptoPath in Nature
Controlling fear: Prefrontal cortex interneurons in action. Using multi-site electrophysiology and optogenetic, Dr Herry’s group reveals that persistent fear behavior, which is at the core of psychiatric conditions such as anxiety disorders, might be finely regulated at the level of specific prefrontal inhibitory circuits.[ read more ]Share on
