S., Izquierdo, M. A., Cristaudo, S., Hernández, O., Pérez-González, D., Covey, E., & Oliver, D. L. (2008). A discontinuous tonotopic organization in the inferior colliculus of the rat. The Journal of neuroscience : the official journal of the Society for Neuroscience, 28(18), 4767–4776. 0270-6474 http://hdl.handle.net/10366/154496 10.1523/JNEUROSCI.0238-08.2008 1529-2401 [EN]Audible frequencies of sound are encoded in a continuous manner along the length of the cochlea, and frequency is transmitted to the brain as a representation of place on the basilar membrane. The resulting tonotopic map has been assumed to be a continuous smooth progression from low to high frequency throughout the central auditory system. Here, physiological and anatomical data show that best frequency is represented in a discontinuous manner in the inferior colliculus, the major auditory structure of the midbrain. Multiunit maps demonstrate a distinct stepwise organization in the order of best frequency progression. Furthermore, independent data from single neurons show that best frequencies at octave intervals of approximately one-third are more prevalent than others. These data suggest that, in the inferior colliculus, there is a defined space of tissue devoted to a given frequency, and input within this frequency band may be pooled for higher-level processing. eng Attribution-NonCommercial-NoDerivatives 4.0 Internacional http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Auditory Inferiorcolliculus Tonotopic organization Laminar organization 3-D reconstruction Critical bands A Discontinuous Tonotopic Organization in the Inferior Colliculus of the Rat info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://www.jneurosci.org/content/28/18/4767 Ministerio de Educación y Ciencia (MEC) BFU2006-00572 Junta de Castilla y León (JCYL) SA 007C05 Ministerio de Educación y Ciencia (MEC) SAB2004-0076 National Institutes of Health R01 DC00189 National Institutes of Health DC-00607 National Institutes of Health DC-00287 Ministerio de Educación y Ciencia (MEC) BFU2006-00572 Ministerio de Educación y Ciencia (MEC) AP2005-5166 The Journal of Neuroscience 28 18 4767 4776
