Karel Svoboda is the Director of the Allen Institute for Neural Dynamics. Svoboda’s work is at the intersection of neuronal biophysics and cognition. His current focus is to identify core principles and mechanisms underlying information processing in brain-wide neural circuits. Svoboda is also developing new optical, electrical and molecular methods to interrogate neural function in intact brains. Svoboda earned a PhD in Biophysics (1994) from Harvard University. He was a postdoctoral fellow at Bell Laboratories (until 1997), a principal investigator at Cold Spring Harbor Laboratories (until 2006), and a Senior Group Leader at HHMI’s Janelia Research Campus (until 2020).

报告摘要
Illuminating synaptic learning
How do synapses in the middle of the brain know how to adjust their weight to advance a behavioral goal (i.e. learning)? This is referred to as the synaptic ‘credit assignment problem’. A large variety of synaptic learning rules have been proposed, mainly in the context of artificial neural networks. The most powerful learning rules (e.g. back-propagation of error) are thought to be biologically implausible, whereas the widely studied biological learning rules (Hebbian) are insufficient for goal-directed learning. I will describe ongoing work focused on understanding synaptic learning rules in the cortex in a brain-computer interface task.
