Antonia Marin Burgin, from the Biomedicine Research Institute of Buenos Aires, will be presenting on the "Interaction among excitatory and inhibitory circuits in the hippocampus during adult neurogenesis." http://tdlc.ucsd.edu/research/DNS/speakers/Burgin.html Abstract: The hippocampus is a brain area that is involved in a variety of functions related to the formation of memory and the representation of space. All areas of the hippocampus, and of most parts of the brain, contain excitatory and inhibitory neurons that form individual microcircuits. It is in the interaction between excitatory and inhibitory circuits where appropriate functional responses arise. We study how excitation and inhibition interact to activate neurons in the dentate gyrus of the hippocampus, one of the few regions of the brain in which new neurons are being formed throughout life. In this seminar I will present experiments using electrophysiology and calcium imaging aiming to understand the functional role of newborn neurons in the processing of afferent stimuli, with the focus on synaptic and circuit mechanisms that generate the unique properties they present. Bio: Dr. Antonia Marin-Burgin received her Ph.D. in Biological Sciences at the University of Buenos Aires (2000). She completed a research internship at the Institute of Physiology at the University of Wuerzburg, Germany (1999–2001), and then became a Postdoctoral Fellow at UC San Diego (2002–2008). In 2009, she returned to Argentina as a Researcher from CONICET, where she worked at the Laboratory of Neuronal Plasticity at the Leloir Institute (2009–2012).
