This book was released on 2011 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: The neural correlates of episodic encoding have been studied using functional magnetic resonance imaging (fMRI) in conjunction with the `subsequent memory procedure'. In this procedure, neural activity elicited by individual items during a study phase are contrasted according to performance on a later memory test, allowing for the identification of candidate brain regions that support later memory. The cortical loci of these `subsequent memory effects' have been shown to vary according to the features emphasized at study, and have also been shown to co-localize to regions engaged during the on-line processing of the study episode. However, as prior studies have almost exclusively employed visual items, it is not currently known to what extent these principles generalize to auditory items. The aim of the present body of work was to characterize the neural correlates of encoding auditory information. The experiments described in Chapters 3 and 4 investigated whether auditory items are similarly sensitive to manipulations of study material and encoding task, respectively. The experiment in Chapter 5 analyzed a common encoding condition across the experiments reported in Chapters 3 and 4, and aimed to determine whether subsequent memory effects are similarly sensitive to differences in experimental context. The experiments in Chapters 6 and 7 investigated the neural correlates of across-modality contextual encoding, while the experiment in Chapter 7 additionally investigated across-modality multifeatural encoding. The findings from these experiments indicate that subsequent memory effects dissociate according to study material, encoding task, experimental context, as well as the nature of the contextual feature being encoded. Additionally, the experiments described in Chapters 6 and 7 suggest that the encoding of auditory contextual information requires additional hippocampal resources than does the encoding of visual contextual information. Collectively, these findings support the proposal that the encoding operations supporting memory for a specific event are represented in terms of the processes engaged during the initial experience of that event.

Download or read book Neural Correlates of Auditory Perceptual Organization Measured with Direct Cortical Recordings in Humans written by Andrew Richard Dykstra and published by . This book was released on 2011 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the primary functions of the human auditory system is to separate the complex mixture of sound arriving at the ears into neural representations of individual sound sources. This function is thought to be crucial for survival and communication in noisy settings, and allows listeners to selectively and dynamically attend to a sound source of interest while suppressing irrelevant information. How the brain works to perceptually organize the acoustic environment remains unclear despite the multitude of recent studies utilizing microelectrode recordings in experimental animals or non-invasive human neuroimaging. In particular, the role that brain areas outside the auditory cortex might play is, comparatively, vastly understudied. The experiments described in this thesis combined classic behavioral paradigms with electrical recordings made directly from the cortical surface of neurosurgical patients undergoing clinically-indicated invasive monitoring for localization of epileptogenic foci. By sampling from widespread brain areas with high temporal resolution while participants simultaneously engaged in streaming and jittered multi-tone masking paradigms, the present experiments sought to overcome limitations inherent in previous work, namely sampling extent, resolution in time and space, and direct knowledge of the perceptual experience of the listener. In experiment 1, participants listened to sequences of tones alternating in frequency (i.e., ABA-) and indicated whether they perceived the tones as grouped ("1 stream") or segregated ("2 streams"). As has been reported in neurologically-normal listeners since the 1950s, patients heard the sequences as grouped when the frequency separation between the A and B tones was small and segregated when it was large. Evoked potentials from widespread brain areas showed amplitude correlations with frequency separation but surprisingly did not differ based solely on perceptual organization in the absence of changes in the stimuli. In experiment 2, participants listened to sequences of jittered multi-tone masking stimuli on which a regularly-repeating target stream of tones was sometimes superimposed and indicated when they heard the target stream. Target detectability, as indexed behaviorally, increased throughout the course of each sequence. Evoked potentials and high-gamma activity differed strongly based on the listener's subjective perception of the target tones. These results extend and constrain theories of how the brain subserves auditory perceptual organization and suggests several new avenues of research for understanding the neural mechanisms underlying this critical function.

Download or read book The Cognitive Neuroscience of Memory written by Amanda Parker and published by Psychology Press. This book was released on 2005-08-18 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in techniques available to memory researchers have led to a rapid expansion in the field of cognitive neuroscience of memory. This book provides accessible coverage of four key areas of recent advance, including research on functional imaging, electrophysiological and lesion studies, and developments from the computational modelling approach. The first section reviews functional imaging studies in humans, with particular emphasis on how imaging methods have clarified the cortical areas involved in memory formation and retrieval. The second section describes electrophysiological and lesion research in monkeys, where lesion and disconnection studies are rapidly adding to our knowledge of both information processing and modulatory aspects of memory formation. In the third section, electrophysiological and lesion studies in rats are reviewed allowing for a detailed study of the role of novelty and exploration in memory formation. The final section reviews current research in computational modelling which has allowed the development of new theoretical and experimental approaches to the study of memory encoding and retrieval. This volume draws together the current developments in each field, allowing the synthesis of ideas and providing converging evidence from a range of sources. It will be a useful resource for both advanced undergraduate and postgraduate students of psychology, as well as researchers in the field and anyone with an interest in cognitive neuroscience.

Download or read book The Cambridge Handbook of Cognitive Aging written by Ayanna K. Thomas and published by Cambridge University Press. This book was released on 2020-05-28 with total page 1019 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decades of research have demonstrated that normal aging is accompanied by cognitive change. Much of this change has been conceptualized as a decline in function. However, age-related changes are not universal, and decrements in older adult performance may be moderated by experience, genetics, and environmental factors. Cognitive aging research to date has also largely emphasized biological changes in the brain, with less evaluation of the range of external contributors to behavioral manifestations of age-related decrements in performance. This handbook provides a comprehensive overview of cutting-edge cognitive aging research through the lens of a life course perspective that takes into account both behavioral and neural changes. Focusing on the fundamental principles that characterize a life course approach - genetics, early life experiences, motivation, emotion, social contexts, and lifestyle interventions - this handbook is an essential resource for researchers in cognition, aging, and gerontology.
