Título: Neural oscillations and birdsong rhythms:
from biomechanics to neural dynamics
Resumo: Birdsong is a complex motor activity that emerges from the interaction between the central and peripheral nervous systems, with the body and the environment. The similarities with human speech, both in production and learning, have positioned songbirds as highly useful animal models to study this learned motor skill.
In this talk I will show an interdisciplinary approach to study the emergence of behavior. Specifically I will discuss a biomechanical model for song production and its validation through neural experiments. I will show how this model can be used to make predictions regarding motor control and how it can suggest a hierarchy of importance of the physiological parameters.
I will also show neuronal recordings in a telencephalic region where a sensori-motor integration occurs, showing the presence of well-defined oscillations in local field potentials, which are synchronized to the rhythm of the canary (Serinus canaria) song. I will also show that there is a correspondence between local field potentials, multiunit activity, and single unit activity within the same brain region. A low- dimensional mathematical model for a neural network will be presented that can
reproduce the neural dynamics observed in the experiments.
This interdisciplinary work shows how low-dimensional models can be a valuable tool to study the neuroscience of perception, generation and control of complex motor tasks.
Bio: Ana Amador is a professor at the Physics Department of the School of Sciences at the University of Buenos Aires, Argentina, since 2018. She is also a Research Associate at the National Scientific and Technical Research Council of Argentina (CONICET) since 2013.
After finishing her undergraduate studies in Physics at the University of Buenos Aires, she won a scholarship for a research project in epidemics dynamics at the University of Pernambuco, Brazil. After that experience, she returned to Buenos Aires to complete her Ph.D. studies in Physics with Gabriel Mindlin at the University of Buenos Aires, where she graduated with honors in 2009. During her Ph.D. research, she performed interdisciplinary studies, putting together dynamical systems and experiments for studying the physiology of birdsong production.
In 2009, Ana won a cross-disciplinary scholarship from the Human Frontiers Science Program Organization to perform postdoctoral studies and research with Daniel Margoliash at the University of Chicago, USA. From one of the works developed there, a paper in Nature was published, that has been highlighted by Nature’s Editor Editorial Board (best 2013 Editor’s Selections) and by Physics Today, among others.
In 2012 she returned to Argentina with a repatriation scholarship granted by CONICET, Argentina. Since then, she has developed an innovative experimental line which includes the recording of neuronal bio-potentials in behaving animals. This research work includes the development of specific recording equipment as well as the development of software for data acquisition and analysis. In collaboration with Dr. Mindlin, he has reinforced an interdisciplinary line of data analysis and modeling within the framework of Nonlinear Dynamics.
Ana has been the advisor of 1 postdoc, 4 Ph.D. students, and 3 Master students. During her scientific career, she has also been a Physics Department Council representative in several occasions and has participate in different Science Outreach Programs and Gender Programs. As an example of her interdisciplinary nature and her bonds to the community, Ana is currently Professor councilor at the Physics Department, councilor at the International Society of Neuroethology, and president of the Buenos Aires branch of the Argentine Physics Association (AFA).
Ana is a theoretical-experimental physicist and her research interests are biomechanics, neurophysiology, neuroethology, non-linear dynamics and, in a more specific area, the production and perception of birdsongs.
