![[movies]](/images/mediatype_movies.gif) | Bard Ermentrout: What makes a neuron spike: Optimality, noise, and phase resetting - Redwood Center for Theoretical Neuroscience
Note: There was a mixup. This entry is NOT the talk by Bard Ermentrout. Hopefully the correct talk will be put in place towards the end of November. Seminar by Bard Ermentrout, University of Pittsburgh on October 30, 2008. Given to the Redwood Center for Theoretical Neuroscience at UC Berkeley. Abstract: I will describe behavior of nearly regularly firing neurons in the presence of noisy stimuli. I first describe the phase resetting curve (PRC) and how it responds to noisy inputs...

Talk given by Ole Jensen of the Donders Institute at University Nijmegen, Netherlands. Given to the Redwood Center for Theoretical Neuroscience at UC Berkeley on June 24, 2009. Abstract. The working brain is composed of multiple networks which must be flexibly engaged and disengaged. How is this functional architecture shaped? Recent electrophysiological studies strongly suggest that networks not important for a given task are disengaged by an increase in oscillatory alpha activity (8-13 Hz)...

Abstract: Neural development is a complex process that results from the interaction of many underlying physiological mechanisms. Over the past few decades, computational modellers have produced many models which describe how one or a few of these mechanisms might be responsible for experimentally observed patterns of development...

Abstract: A striking feature of many sensory processing problems is that there appear to be many more neurons engaged in the internal representations of the signal than in its transduction. For example, humans have about 30,000 cochlear neurons, but at least a thousand times as many neurons in the audi...

Unfortunately, the first half was not recorded because of technical problems. Sorry! Abstract: There are two basic problems in the statistical analysis of neural data. The ``encoding'' problem concerns how information is encoded in neural spike trains: can we predict the responses of a neuron (or population of neurons), given an arbitrary stimulus or observed motor be...

This is a talk given by Geoff Hinton, Dept. of Computer Science, University of Toronto, at the Redwood Center for Theoretical Neuroscience on November 27, 2007. Abstract. Neurons need to represent both the presence of a feature in the sensory input and the derivative of an error function with respect to the neural activity. I will describe a simple way in which they can represent both of these very different quantities at the same time and show that this representational scheme would make it eas...
