Time-Warp–Invariant Neuronal Processing
Fluctuations in the temporal durations of sensory signals constitute a major source of variability within natural stimulus ensembles. The neuronal mechanisms through which sensory systems can stabilize perception against such fluctuations are largely unknown. An intriguing instantiation of such robustness occurs in human speech perception, which relies critically on temporal acoustic cues that ...
متن کاملFrom Neuronal Models to Neuronal Dynamics and Image Processing
Neurons make contacts with each other by synapses: The presynaptic neuron sends its output to the synapse via an axon, and the postsynaptic neuron receives it via its dendritic tree (“dendrite”). Most neurons produce their output in form of virtually binary events (action potentials or spikes). Some classes of neurons (e.g., in the retina) nevertheless do not generate spikes but show continuous...
متن کاملUsing neuronal latency to determine sensory-motor processing pathways in reaction time tasks.
We describe a new technique that uses the timing of neuronal and behavioral responses to explore the contributions of individual neurons to specific behaviors. The approach uses both the mean neuronal latency and the trial-by-trial covariance between neuronal latency and behavioral response. Reliable measurements of these values were obtained from single-unit recordings made from anterior infer...

متن کاملDistributed processing in cultured neuronal networks.
Thanks to a number of recent technical advances, it will become increasingly popular to study the very basics of distributed information processing using cultured neuronal networks. Most researchers studying population coding are working with intact, living animals. Clearly, cultured neuronal networks lack many features of real brains, but they retain many others. They develop organotypic synap...
