Wiring and rewiring bilateral nervous circuits
Fecha y hora
8 de febrero de 2023 15:30
Most metazoans, including humans, are bilaterally symmetric and many features of the mature neural function, including vision, depends on the coherent communication between the two brain hemispheres. Bilateral circuits containing contra- and ipsilaterally projecting axons that respectively cross or avoid the midline to send sensory input to each hemisphere, are essential to integrate sensory information and elaborate coordinated motor responses. I will present some of the past contributions and current findings from our laboratory on the molecular mechanisms underlying the formation of bilateral circuits and explain the consequences of altering these circuits.
Affiliation and short bio
Eloisa Herrera is a full Professor and Principal Investigator at the Institute of Neuroscience in Alicante (IN, Spain) that belongs to the Spanish Research Council and the University Miguel Hernández. She did her PhD at the National Center of Biotechnology in Madrid, working in Cancer and Aging. Then, she moved to Columbia University (NY, USA) to work on Developmental Neurosciences in the group of Prof. Carol Mason. In 2005, she returned to Spain to establish her own group in Alicante. Along the years her team has largely contributed to identify many of the molecular mechanisms underlying axonal navigation during the wiring of bilateral circuits. She has been an ERCGrant holder and has been was awarded with the Career Development Award from the Human Frontier Science Program and the Alberto Sols Prize.
