A Spike-Based Model of Binaural Sound Localization
نویسندگان
چکیده
This paper describes a spike-based model of binaural sound localization using interaural time differences (ITDs). To handle the problem of temporal coding and to facilitate a hardware implementation all neurons are simulated by a spike response model, which includes postsynaptic potentials (PSPs) and a refractory period. A winner-take-all (WTA) network selects the dominant source from the representation of the sound's angles of incidences, and can be biased by a multisensory support. We use simulations on real audio data to investigate the function and the practical application of the system.

Stochastic model explains role of excitation and inhibition in binaural sound localization in mammals
Short title: Excitation and inhibition in binaural sound localization Summary Interaural time differences (ITDs), the differences of arrival time of the sound at the two ears, provide a major cue for low-frequency sound localization in the horizontal plane. The first nucleus involved in the computation of ITDs is the medial superior olive (MSO). We model the neural circuit of the MSO using a st...
متن کاملEncoding of sound localization cues by an identified auditory interneuron: effects of stimulus temporal pattern.
An important cue for sound localization is binaural comparison of stimulus intensity. Two features of neuronal responses, response strength, i.e., spike count and/or rate, and response latency, vary with stimulus intensity, and binaural comparison of either or both might underlie localization. Previous studies at the receptor-neuron level showed that these response features are affected by the ...

We describe a biological inspired model of binaural sound localization using interaural time di erences (ITDs). To handle the problem of temporal coding and to facilitate a hardware implementation in analog VLSI, the simulation of the system is based on a spike response model. This neuron model takes up physiological properties like postsynaptic potentials (PSPs) and a refractory period. A winn...
متن کاملSpike-Timing-Based Computation in Sound Localization
Spike timing is precise in the auditory system and it has been argued that it conveys information about auditory stimuli, in particular about the location of a sound source. However, beyond simple time differences, the way in which neurons might extract this information is unclear and the potential computational advantages are unknown. The computational difficulty of this task for an animal is ...
متن کاملLocalization and identification of concurrent sounds in the owl's auditory space map.
In nature, sounds from multiple sources sum at the eardrums, generating complex cues for sound localization and identification. In this clutter, the auditory system must determine "what is where." We examined this process in the auditory space map of the barn owl's (Tyto alba) inferior colliculus using two spatially separated sources simultaneously emitting uncorrelated noise bursts, which were...
