Representation of speech categories in the primate auditory cortex.
A "ventral" auditory pathway in nonhuman primates that originates in the core auditory cortex and ends in the prefrontal cortex is thought to be involved in components of nonspatial auditory processing. Previous work from our laboratory has indicated that neurons in the prefrontal cortex reflect monkeys' decisions during categorical judgments. Here, we tested the role of the superior temporal g...
متن کاملRepresentation of Reward Feedback in Primate Auditory Cortex
It is well established that auditory cortex is plastic on different time scales and that this plasticity is driven by the reinforcement that is used to motivate subjects to learn or to perform an auditory task. Motivated by these findings, we study in detail properties of neuronal firing in auditory cortex that is related to reward feedback. We recorded from the auditory cortex of two monkeys w...
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 کاملAuditory Cortex: Representation through Sparsification?
melanoma cells could be reversibly converted into pigmented melanoma cells, although the conversion toward the pigmented state is favored. Thus, invasive melanoma cells are in a metastable state allowing them to migrate or become stationary according to the local environment. TGFb signaling was directly controlling the pigmented status of melanoma cells by regulating Brn2 expression. However, b...
