Book excerpt: Mammals discriminate temporal “shape†cues in speech and other sounds but the underlying neural pathways and mechanisms remain a mystery. Shape cues include the rising and falling slopes and the duration of change in the sound envelope amplitude over time and are critical for sound perception. The auditory cortices are essential for behavioral discrimination of temporal cues and yet the neural mechanisms underlying this ability remain unknown. Primary (A1) and ventral non-primary auditory cortical fields (VAF SRAF) are physiologically and anatomically organized and specialized to represent distinct spectral and spatial cues in sound. The current study investigates cortical field differences for encoding envelope shape in sound. In the present study, we ask whether A1, VAF and SRAF could utilize spike rate, distinct temporal spiking patterns, including onset and sustained components, to discriminate sound shape. To address these questions we computed a discrimination index based on the spike distance metric. We find response durations and optimal time constants for discriminating sound shape increase in rank order with: A1

This book was released on 2013 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human auditory system easily solves the "cocktail party problem"--That is, even when multiple people are speaking at once, we can easily select and pay attention to a single voice while ignoring the others. Though this seems easy to do, the problem is known to be quite computationally complex. It requires identifying the important sound, selecting it for special processing, and using information from it to make behavioral decisions; meanwhile, the other voices must not be allowed to distract us. How does the brain do this? In chapter 1, I review previous approaches to this question and motivate the choices I made in designing my experiments. In chapter 2, I present the data and conclusions I obtained in collaboration with my advisor, Dr Michael DeWeese. (We are submitting this chapter for publication separately.) In chapter 3, I present a detailed protocol for repeating our behavioral results. The final chapter, Chapter 4, is broader in scope. I discuss how our models and results relate to existing models of prefrontal control over other brain regions. Finally, I consider what my results have taught me about the scientific process of investigating neural function and ruminate on where this field may be headed next.
Download or read book Encoding of Ultrasonic Communication Signals in Rat Auditory Cortex written by Isaac Michael Carruthers and published by . This book was released on 2015 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: All social animals require a means of communication, and for many species that need is filled by the use of vocalizations. While far less intricate than human speech, many animals employ systems of vocalizations in order to attract mates, convey information about the environment, or to express an emotional state. One such animal is the rat, which communicates via a set of ultra-sonic vocalizations (USVs) in the 50kHz frequency range. These USVs have a conveniently simple structure, making them easy to synthesize and modify. The rat thus provides an excellent model system with which to probe the processing and encoding of such communication signals in the mammalian brain.
Download or read book The Auditory Cortex written by Jeffery A. Winer and published by Springer Science & Business Media. This book was released on 2010-12-02 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been substantial progress in understanding the contributions of the auditory forebrain to hearing, sound localization, communication, emotive behavior, and cognition. The Auditory Cortex covers the latest knowledge about the auditory forebrain, including the auditory cortex as well as the medial geniculate body in the thalamus. This book will cover all important aspects of the auditory forebrain organization and function, integrating the auditory thalamus and cortex into a smooth, coherent whole. Volume One covers basic auditory neuroscience. It complements The Auditory Cortex, Volume 2: Integrative Neuroscience, which takes a more applied/clinical perspective.

Available in PDF, EPUB and Kindle. Book excerpt: Connecting the auditory brain stem to sensory, motor, and limbic systems, the inferior colliculus is a critical midbrain station for auditory processing. Winer and Schreiner's The Inferior Colliculus, a critical, comprehensive reference, presents the current knowledge of the inferior colliculus from a variety of perspectives, including anatomical, physiological, developmental, neurochemical, biophysical, neuroethological and clinical vantage points. Written by leading researchers in the field, the book is an ideal introduction to the inferior colliculus and central auditory processing for clinicians, otolaryngologists, graduate and postgraduate research workers in the auditory and other sensory-motor systems.
Download or read book Elementary Signal Detection Theory written by Thomas D. Wickens and published by Oxford University Press. This book was released on 2001-10-11 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Signal detection theory, as developed in electrical engineering and based on statistical decision theory, was first applied to human sensory discrimination about 40 years ago. The theory's intent was to explain how humans discriminate and how we might use reliable measures to quantify this ability. An interesting finding of this work is that decisions are involved even in the simplest of discrimination tasks--say, determining whether or not a sound has been heard (a yes-no decision). Detection theory has been applied to a host of varied problems (for example, measuring the accuracy of diagnostic systems, survey research, reliability of lie detection tests) and extends far beyond the detection of signals. This book is a primer on signal detection theory, useful for both undergraduates and graduate students.
