Anesthesia changes frequency tuning of neurons in the rat primary auditory cortex.
The vast majority of investigations on central auditory processing so far were conducted under the influence of an anesthetic agent. It remains unclear, however, to what extend even basic response properties of central auditory neurons are influenced by this experimental manipulation. We used a combination of chronic recording in unrestrained animals, computer-controlled randomized acoustic sti...
متن کاملRapid tuning shifts in human auditory cortex enhance speech intelligibility
Experience shapes our perception of the world on a moment-to-moment basis. This robust perceptual effect of experience parallels a change in the neural representation of stimulus features, though the nature of this representation and its plasticity are not well-understood. Spectrotemporal receptive field (STRF) mapping describes the neural response to acoustic features, and has been used to stu...
متن کاملFine frequency tuning in monkey auditory cortex and thalamus.
The frequency resolution of neurons throughout the ascending auditory pathway is important for understanding how sounds are processed. In many animal studies, the frequency tuning widths are about 1/5th octave wide in auditory nerve fibers and much wider in auditory cortex neurons. Psychophysical studies show that humans are capable of discriminating far finer frequency differences. A recent st...
متن کاملTuning in to sound: frequency-selective attentional filter in human primary auditory cortex.
Cocktail parties, busy streets, and other noisy environments pose a difficult challenge to the auditory system: how to focus attention on selected sounds while ignoring others? Neurons of primary auditory cortex, many of which are sharply tuned to sound frequency, could help solve this problem by filtering selected sound information based on frequency-content. To investigate whether this occurs...
متن کاملTitle: Fine Frequency Tuning in Monkey Auditory Cortex and Thalamus
23 The frequency resolution of auditory neurons throughout the ascending auditory pathway 24 is an important parameter for understanding how sounds are processed. It has been shown in 25 previous animal studies that the frequency tuning widths are about 1/5 octave wide in auditory 26 nerve fibers and much wider in auditory cortex neurons (Pickles, 1979; McLaughlin et al., 2008; 27 see Table 1)....
