Modeling complex responses of FM-sensitive cells in the auditory midbrain using a committee machine.
Frequency modulation (FM) is an important building block of complex sounds that include speech signals. Exploring the neural mechanisms of FM coding with computer modeling could help understand how speech sounds are processed in the brain. Here, we modeled the single unit responses of auditory neurons recorded from the midbrain of anesthetized rats. These neurons displayed spectral temporal rec...
متن کاملSpeech perception through FM auditory trainers in noise and reverberation.
Speech perception through FM auditory trainers was explored in conditions of noise and reverberation. Special attention was paid to the mode of transmission and individual capabilities of various commercially-available units to handle speech in noise and reverberation. Results indicate an overwhelming advantage of FM transmission for maintaining speech intelligibility in noise and reverberation...
متن کاملAuditory lexical decision, categorical perception, and FM direction discrimination differentially engage left and right auditory cortex.
Recent neuroimaging and neuropsychological data suggest that speech perception is supported in bilaterally auditory areas. We evaluate this issue building on well-known behavioral effects. While undergoing positron emission tomography (PET), subjects performed standard auditory tasks: direction discrimination of frequency-modulated (FM) tones, categorical perception (CP) of consonant-vowel (CV)...
متن کاملSelective attention in an insect auditory neuron.
Previous work (Pollack, 1986) showed that an identified auditory neuron of crickets, the omega neuron, selectively encodes the temporal structure of an ipsilateral sound stimulus when a contralateral stimulus is presented simultaneously, even though the contralateral stimulus is clearly encoded when it is presented alone. The present paper investigates the physiological basis for this selective...
متن کاملSyntax processing by auditory cortical neurons in the FM-FM area of the mustached bat Pteronotus parnellii.
Syntax denotes a rule system that allows one to predict the sequencing of communication signals. Despite its significance for both human speech processing and animal acoustic communication, the representation of syntactic structure in the mammalian brain has not been studied electrophysiologically at the single-unit level. In the search for a neuronal correlate for syntax, we used playback of n...
