You can submit questions through the registration and will have the opportunity to pose questions during the webinar through a Q&A box.
Below is the significance statement of Interoception Primes Emotional Processing: Multimodal Evidence from Neurodegeneration, published on April 7, 2021, in JNeurosci and authored by Paula C. Salamone, Agustina Legaz, Lucas Sedeño, Sebastián Moguilner, Matías Fraile-Vazquez, Cecilia Gonzalez Campo, Sol Fittipaldi, Adrián Yoris, Magdalena Miranda, Agustina Birba, Agostina Galiani, Sofía Abrevaya, Alejandra Neely, Miguel Martorell Caro, Florencia Alifano, Roque Villagra, Florencia Anunziata, Maira Okada de Oliveira, Ricardo M. Pautassi, Andrea Slachevsky, Cecilia Serrano, Adolfo M. García, and Agustín Ibañez.
Salamone, Legaz, et al. examined whether and how emotions are primed by interoceptive states combining multimodal measures in healthy controls and neurodegenerative models. In controls, negative emotion recognition and ongoing heart-evoked potential modulations were increased after interoception. These patterns were selectively disrupted in patients with atrophy across key interoceptive-emotional regions (e.g., the insula and the cingulate in frontotemporal dementia, frontostriatal networks in Parkinson’s disease), whereas persons with Alzheimer’s disease presented generalized emotional processing abnormalities with preserved interoceptive mechanisms. The integration of both domains was associated to the volume and connectivity (salience network) of canonical interoceptive-emotional hubs, critically involving the insula and the anterior cingulate. This study reveals multimodal markers of interoceptive-emotional priming, laying the groundwork for new agendas in cognitive neuroscience and behavioral neurology.
Marina Picciotto, PhD
Marina Picciotto is Charles B.G. Murphy Professor in psychiatry, professor of neurobiology and pharmacology in the child study center, and deputy chair for basic science at Yale University. She is also the deputy director of the Kavli Institute for Neuroscience. Picciotto is the editor-in-chief of The Journal of Neuroscience and president-elect of the Society for Research on Nicotine and Tobacco. She previously served on the Scientific Council of the National Institute on Drug Abuse and as the treasurer of SfN. Her research interests lie in the role of nicotinic acetylcholine receptors in mouse models, including research related to addiction, depression, brain development, learning and appetite. She earned her BS in biology from Stanford University, PhD in neuroscience from Rockefeller University, and completed her postdoctoral training at the Pasteur Institute.
Agustín Ibáñez, PhD
Agustin Ibáñez is the director of the Latin American Brain Health Institute, and the Cognitive Neuroscience Center. Ibáñez is also Senior Atlantic Fellow at the Global Brain Health Institute, University of California, San Francisco, Trinity College Dublin, Ireland. His research interests lie in global approaches to dementia and social, cognitive, and affective neuroscience. He received his undergraduate degree in psychology and his PhD at the Pontifical Catholic University of Chile, he completed his postdoctoral training in neuroscience at University of Heidelberg, Germany.
Paula Celeste Salamone, Phd
Paula C. Salamone is a postdoctoral research fellow at Linköping University. Salamone previously was a PhD fellow at the Cognitive Neuroscience Center (UdeSA, Argentina), employed by the Argentinean Research Council (CONICET). Her main research interests lie in affective neuroscience and interoception in neuropsychiatric conditions or through experimental interventions using multimodal techniques (such as, behavior, EEG, fMRI). She received her degree in psychology from University of Palermo and her PhD in neuroscience from National University of Cordoba, she also did an extended research collaboration with Erno Herman’s CANLAB group from the Donders Institute. She is now studying affective touch and interoception as a postdoc fellow in Rebecca Böhme’s lab at the CSAN, Linköping University.
