Auditory modulation of visual stimulus encoding in human retinotopic cortex
Sounds can modulate visual perception as well as neural activity in retinotopic cortex. Most studies in this context investigated how sounds change neural amplitude and oscillatory phase reset in visual cortex. However, recent studies in macaque monkeys show that congruence of audio-visual stimuli also modulates the amount of stimulus information carried by spiking activity of primary auditory ...
متن کاملEncoding frequency contrast in primate auditory cortex.
Changes in amplitude and frequency jointly determine much of the communicative significance of complex acoustic signals, including human speech. We have previously described responses of neurons in the core auditory cortex of awake rhesus macaques to sinusoidal amplitude modulation (SAM) signals. Here we report a complementary study of sinusoidal frequency modulation (SFM) in the same neurons. ...
متن کاملHigh-level and Low-level Processing in the Auditory System: The Role of Primary Auditory Cortex
In spite of a large number of studies at different levels of the auditory system, there is still no satisfactory physiological account for the perception of speech. We argue here that many of the problems in creating such an account are common to other processing tasks of the auditory system, such as the extraction of pitch and sound localization. These difficulties are related to the global as...
متن کاملMillisecond encoding precision of auditory cortex neurons.
Neurons in auditory cortex are central to our perception of sounds. However, the underlying neural codes, and the relevance of millisecond-precise spike timing in particular, remain debated. Here, we addressed this issue in the auditory cortex of alert nonhuman primates by quantifying the amount of information carried by precise spike timing about complex sounds presented for extended periods o...
متن کاملMotion direction tuning in human visual cortex.
A number of electrophysiological studies have been conducted in recent years in order to clarify the dynamics of visual motion processing in the human brain. Using a variety of event-related potential (ERP) measures, several parameters such as onset, offset, contrast and velocity have been investigated, while a critical aspect of visual motion, that of direction, has received less attention. He...
