Full textDuring natural conversation, we send rich acoustic signals that do not only determine the content of conversation but also provide a wealth of information about the person speaking. Traditionally, the question of how we understand speech has been studied separately from the question of how we recognize the person speaking either implicitly or explicitly assuming that speech and speaker recognition are two independent processes. Recent studies, however, suggest integration in the processing of speech and speaker information. In this thesis, I provide further empirical evidence that processes involved in the analysis of speech and speaker information interact on the neural and behavioral level. In Study 1, I present data from an experiment which used functional magnetic resonance imaging (fMRI) to investigate the neural basis for speech recognition under varying speaker conditions. The results of this study suggest a neural mechanism that exploits functional interactions between speech- and speaker-sensitive areas in left and right hemispheres to allow for robust speech recognition in the context of speaker variations. This mechanism assumes that speech recognition, including the recognition of linguistic prosody, predominantly involves areas in the left hemisphere. In Study 2, I present two fMRI experiments that investigated the hemispheric lateralization of linguistic prosody recognition in comparison to the recognition of the speech message and speaker identity, respectively. The results showed a clear left-lateralization when recognition of linguistic prosody was compared to speaker recognition. Study 3 investigated under which conditions listeners benefit from prior exposure to a speaker''s voice in speech recognition. The results suggest that listeners implicitly learn acoustic speaker information during a speech task and use such information to improve comprehension of speech in noise.

Full textThis thesis focuses on the development of new in-situ methods of characterization based on the electron spectroscopies (XPS and EPES) coupled with theoretical calculations obtained through Monte-Carlo simulations in order to perform very precise quantitative studies. The first part of this thesis was devoted to quantitative studies of XPS and MM-EPES measurements. Firstly, the correction function of a hemispherical analyzer (HSA) which is a combination of the analysis area (A) and the transmission (T) was determined using a new method based on the elastic images. For the first time, the dependence of A on the kinetic energy of electrons was highlighted. Using this function, an in-situ method based on the combination of XPS and MM-EPES modeling was setting up. This method was used to determine the organization of gold film deposed on oxidized silicon substrate. Measurements show that this method is able to determine surface parameters when the microscopy techniques do not give any information in the case of a small quantity of gold deposit (less than 2 nm). The second part of this work was directed towards developing a new generation of microscopy called MM-EPEM which is based on the detection of elastic electrons. The stages required to obtain these images are well described and optimized here. The MM-EPEM images processing was used to study gold growth on different substrates. This technique is a non-destructive method and allows the operator to construct chemical tomography and to determine the nano-organization of the surface

Full textPain is a perceptual experience comprising many dimensions. These pain dimensions interrelate with each other and recruit neuronal networks that process the corresponding information. Elucidating the functional architecture that supports different perceptual aspects of the experience is thus, a fundamental step to our understanding of the functional role of different regions in the cerebral pain matrix that are involved in the cortical circuitry underlying the subjective experience of pain. Among various brain regions involved in the processing of nociceptive information, primary and secondary somatosensory cortices (S1 and S2) are the main areas generally associated with the processing of sensory-discriminative aspect of pain. However the functional organization in these somatosensory areas is not completely clear and relatively few studies have directly examined the integration of information among somatic sensory regions. Thus, several questions remain regarding the hierarchical relationship between S1 and S2, as well as the functional role of the inter-hemispheric connections of the homologous somatic sensory areas. Likewise, the question of serial or parallel processing within the somatosensory system is another questionable issue that requires further investigation. The purpose of the present study was to test a number of causal hypotheses regarding the functional interactions between S1 and S2, while subjects were receiving painful electric shocks. We implemented a connectivity modeling approach, which utilizes a causal description of system dynamics, in order to study the interactions among activation sites defined by a data set derived from a functional imaging study. Our paradigm consists of 3 experimental scans using electric shock stimuli, with the stimulus intensity changing from moderately painful (level 3), to slightly painful (level 2), and to completely non-painful (level 1) during the final scan. Therefore our paradigm allowed us to investigate how stimulus intensity is encoded within our network of interest, and how the connectivity of the different regions is modulated across the different stimulus conditions. Our result is in favor of serial mode of somatosensory processing with thalamocortical input to S1 contralateral to stimulation site. Thus our results implicates that pain information is propogated from S1 contralateral through our network of interest comprising of bilateral S1 and S2. Our analysis indicates that S1→S2 connection is modulated by pain, which suggests that S2 is higher on the hierarchy of pain processing than S1, in accordance with previous neurophysiological and MEG findings. Lastly, our analysis provides evidence for the entrance of somatosensory information into the hemisphere contralateral to the stimulation side, with inter-hemispheric connections responsible for the transfer of information to the ipsilateral hemisphere.

The Japanese encephalitis virus (JEV) can cause meninges inflammation and neuroinflammation, thus leading to lethality. Hence, complete understanding of JEV pathogenesis can benefit the development vaccines to reduce the risk of infection. The capsid protein of JEV affects its ability of infect ion and replication. In this study, we investigated the pathogenesis of JEV by mutating the protein coat at specific locations (D67 and N154). A extremely sensitive nanostructured biosensor that was built by depositing a gold thin film on the barrier layer surface of an anodic aluminum oxide (AAO) as the electrode was developed for detecting the weak binding between the mutated protein coat and receptors. Receptors CLEC5A and DC-SIGN were attached to different electrodes, respectively, as the probes using the self-assembled monolayer (SAM) method. After immobilizing JEVs with mutated protein coat on the probes, electrochemical impedance spectroscopy (EIS) was than implemented for analyzing the binding locations of JEV on different receptors. Experimental results illustrate that the wild-type JEV was able to bind to both DC-SIGN and CLEC5A, with a stronger binding affinity to the former. The non-N-linked glycosylated protein coat at the 154th amino acid displayed a lower binding capacity to CLEC5A than the modified version (N-linked glycosylated). The observation indicates that the 154th amino acid on the JEV protein coat heavily influences the JEV-CLEC5A bindings.
