This book was released on 2012-12-06 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: The full power of combining experiment and theory has yet to be unleashed on studies of the neural mechanisms in the brain involved in acoustic information processing. In recent years, enormous amounts of physiological data have been generated in many laboratories around the world, characterizing electrical responses of neurons to a wide array of acoustic stimuli at all levels of the auditory neuroaxis. Modern approaches of cellular and molecular biology are leading to new understandings of synaptic transmission of acoustic information, while application of modern neuro-anatomical methods is giving us a fairly comprehensive view ofthe bewildering complexity of neural circuitry within and between the major nuclei of the central auditory pathways. Although there is still the need to gather more data at all levels of organization, a ma jor challenge in auditory neuroscience is to develop new frameworks within which existing and future data can be incorporated and unified, and which will guide future laboratory ex perimentation. Here the field can benefit greatly from neural modeling, which in the central auditory system is still in its infancy. Indeed, such an approach is essential if we are to address questions related to perception of complex sounds including human speech, to the many di mensions of spatial hearing, and to the mechanisms that underlie complex acoustico-motor behaviors.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Cortical auditory processing is critical for speech perception, yet we understand little about how the neural representations available at the cortical level allow for sound recognition. In particular, the neural mechanisms for recognition of sounds via spiking patterns are currently unknown, and the characterization of auditory cortical neuron response properties using stimulus-response models remains incomplete. Previous work has shown that spike trains can be used to discriminate between sounds using analytical methods, but how biological circuits might perform such computations remains unclear. Therefore we devised a model for discrimination (inspired by a spike distance metric) that combines a network of integrate-and-fire model neurons with a decision network. We applied this model to the birdsong system, a powerful animal model for the study of audition. We then examined how stimuli could be recognized by sensory systems from spiking patterns by transforming spiking patterns into spatial representations. Previous "spike pattern recognition" models used artificially pre-processed and noiseless signals as input, despite the fact that neural spike trains show variability. Therefore, we used cortical-level neural recordings as input to a novel spike pattern recognition system designed to deal with the intrinsic variability and diverse response properties of cortical spike trains. We show that the model can learn to recognize neural responses to auditory stimuli using spike-timing dependent plasticity, and can play back learned spike patterns in reverse, not unlike the reverse spike train playback observed in hippocampus. A standard model for central auditory neurons is the spectro-temporal receptive field (STRF), which quantifies the spectral and temporal stimulus parameters that modulate neural activity. While the STRF has been used to predict neural responses, a causal connection between the STRF structure and neural responses is lacking. We used an adaptive stimulation paradigm to address this problem. Specifically, for each neuron, we filtered out stimulus frequencies predicted to be unimportant by the STRF (estimated using normalized reverse correlation), and measured responses to these stimuli. For some neurons, this filtering had little effect on neural firing, but adding a noise masker in the unimportant frequency regions adversely affected their responses, suggesting that frequency regions outside the STRF can play a role in determining neural responses.

This book was released on 2019 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The auditory scene that we face during our day life is highly complex. The human auditory system is able to allow us to maintain a conversation with another person whilst ignoring the surrounding sounds but, at the same time, keeping track of what is happening to detect unexpected sounds that can be critical for survival. This suggests that whilst listening, there is an ongoing storage of information about the sounds we have already heard and how they relate to each other, thus allowing the auditory system to form expectations at different levels of complexity about what is going to come. Indeed, repetitive stimulation has been shown to reduce auditory neural activity in the human cerebral cortex and this neural activity that represents immediate or remembered features of a sensory stimulus can be used as evidence when making simple perceptual decisions. Yet, before reaching the auditory cortex, incoming auditory information is deeply processed by nuclei in the subcortical ascending auditory pathway. In a series of three studies carried out in the University of Barcelona and the University of Jyväskylä, we recorded the auditory frequency – following response (FFR) to study the contribution of the subcortical auditory pathway to sound encoding and processing. The FFR to periodic complex sounds provides a non-invasive measure of the neural transcription of sounds, as well as how auditory experiences transform these representations. Although it has been considered as a correlate of subcortical sound encoding, recent studies challenged this assumption, demonstrating that FFR receives major contribution from the auditory cortex. The objective of the present PhD thesis is to investigate how stimulus statistics and temporal predictability modulate regularity encoding in the subcortical auditory pathway and how the encoding strength of sounds in this pathway influences the latter making of simple auditory perceptual decisions. Additionally, we aimed to further characterize the FFR by means of electroencephalography and magnetoencephalography to understand the role of the frequency of the eliciting stimuli and disentangle the anatomical contribution of the FFRs elicited to sounds of different frequencies. Together our findings support the view that regularity encoding spans across the auditory hierarchy. Going a step further, temporal predictability and the frequency of the incoming stimulation also affect the subcortical sound encoding, which is reflected in the making of latter simple auditory perceptual decisions. Indeed, the frequency is a crucial parameter, as the cortical contribution to the FFR is not observable when the frequency of the sounds is around 300 Hz. Overall, we conclude that the subcortical auditory pathway has an active role in the perception and processing of the incoming sounds, consistent with the hypothesis of a distributed network for perceptual organization. Additionally, although the FFR has a multi-generator nature, it can still be used as a window into human subcortical sound encoding when using the appropriate stimulus parameters." -- TDX.

Available in PDF, EPUB and Kindle. Book excerpt: It has become accepted in the neuroscience community that perception and performance are quintessentially multisensory by nature. Using the full palette of modern brain imaging and neuroscience methods, The Neural Bases of Multisensory Processes details current understanding in the neural bases for these phenomena as studied across species, stages of development, and clinical statuses. Organized thematically into nine sub-sections, the book is a collection of contributions by leading scientists in the field. Chapters build generally from basic to applied, allowing readers to ascertain how fundamental science informs the clinical and applied sciences. Topics discussed include: Anatomy, essential for understanding the neural substrates of multisensory processing Neurophysiological bases and how multisensory stimuli can dramatically change the encoding processes for sensory information Combinatorial principles and modeling, focusing on efforts to gain a better mechanistic handle on multisensory operations and their network dynamics Development and plasticity Clinical manifestations and how perception and action are affected by altered sensory experience Attention and spatial representations The last sections of the book focus on naturalistic multisensory processes in three separate contexts: motion signals, multisensory contributions to the perception and generation of communication signals, and how the perception of flavor is generated. The text provides a solid introduction for newcomers and a strong overview of the current state of the field for experts.

Download or read book Neural Correlates of Auditory Processing Following Exposure to an Augmented Acoustic Environment written by Adam Christopher Dziorny and published by . This book was released on 2009 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Each year as many as 3/1000 children are diagnosed with congenital sensorineural hearing loss. Common in these children are delays in grammar comprehension, vocabulary retention and speech development, related to temporal processing abilities. Studies in a mouse model of congenital sensorineural hearing loss suggest that early exposure to an augmented acoustic environment (AAE) limits outer hair cell death and maintains peripheral auditory thresholds. However, there have been no studies on the effects of AAE on neural encoding in the central auditory system. The goal of these experiments is to investigate midbrain auditory processing in a mouse model (the DBA strain) of sensorineural hearing loss, and determine the effects of AAE exposure. It is clear that sound exposure during the early developmental period has profound effects on neural processing in the central auditory system of normal-hearing subjects. Questions remain on the effects of such sound exposure on a model of hearing impairment. In Aim I of this study we presented a novel temporal AAE containing silent gaps embedded in noise bursts to DBA mice and examined the frequency representation, intensity encoding and temporal processing in the auditory midbrain. Mice were exposed to a traditional AAE stimulus, a novel temporal AAE stimulus, or no stimulus from birth to P30. Auditory brainstem responses (ABRs) and distortion product otoacoustic emissions (DPOAEs) were recorded to assess peripheral auditory function. To assess the effects on central auditory processing we recorded neural activity from a 16-channel electrode in the inferior colliculus (IC). We confirmed peripheral preservation with AAE exposure, and expanded these results to demonstrate outer hair cell functional preservation. In the midbrain we demonstrated that IC neurons showed decreased thresholds, that high best-frequency units were maintained, tuning sharpness was improved, excitatory drive was increased and most importantly, units displayed shorter neural gap thresholds. Additionally, only mice exposed to our novel temporal AAE demonstrated significantly shortened mean gap threshold at low carrier levels, and in the presence of continuous background noise. To be useful as a therapeutic intervention the effect of onset time on central auditory function must be examined. Additionally, it is not known if the improvements provided by AAE exposure will remain after exposure cessation. In Aim II of this study we asked whether delaying the exposure onset or altering its duration influence the improvements in neural processing noted above. Again DBA mice were exposed to a traditional AAE stimulus or no stimulus from birth to P60. Two additional groups were included, one exposed for 30 days followed by 30 days of no exposure (On/Off), the other not exposed until P30 followed by 30 days of exposure (Off/On). All animals were tested at P60. Again ABRs and DPOAEs were recorded to assess peripheral auditory function, and central auditory processing was measured using a 16-channel electrode in the IC. We determined that the onset time of exposure is of little importance in demonstrating improvements in both peripheral and central auditory system. However, continued exposure is essential to maintain the beneficial effects and limit functional loss. Our results demonstrate that AAE preserves peripheral structure and function and improves central auditory processing, that a targeted temporal AAE can improve neural correlates of temporal processing, and that the timing of AAE is essential in delaying the progression of sensorineural hearing loss. These experiments pave the way for possible therapeutic intervention in children suffering congenital sensorineural hearing loss."--Leaves v-vi.

Book excerpt: An integrated overview of hearing and the interplay of physical, biological, and psychological processes underlying it. Every time we listen—to speech, to music, to footsteps approaching or retreating—our auditory perception is the result of a long chain of diverse and intricate processes that unfold within the source of the sound itself, in the air, in our ears, and, most of all, in our brains. Hearing is an "everyday miracle" that, despite its staggering complexity, seems effortless. This book offers an integrated account of hearing in terms of the neural processes that take place in different parts of the auditory system. Because hearing results from the interplay of so many physical, biological, and psychological processes, the book pulls together the different aspects of hearing—including acoustics, the mathematics of signal processing, the physiology of the ear and central auditory pathways, psychoacoustics, speech, and music—into a coherent whole.

Book excerpt: Volume 1: The Ear (edited by Paul Fuchs) Volume 2: The Auditory Brain (edited by Alan Palmer and Adrian Rees) Volume 3: Hearing (edited by Chris Plack) Auditory science is one of the fastest growing areas of biomedical research. There are now around 10,000 researchers in auditory science, and ten times that number working in allied professions. This growth is attributable to several major developments: Research on the inner ear has shown that elaborate systems of mechanical, transduction and neural processes serve to improve sensitivity, sharpen frequency tuning, and modulate response of the ear to sound. Most recently, the molecular machinery underlying these phenomena has been explored and described in detail. The development, maintenance, and repair of the ear are also subjects of contemporary interest at the molecular level, as is the genetics of hearing disorders due to cochlear malfunctions.
