  1. 1. Effects of Vagus Nerve Stimulation and Ketogenic Diet on Quality of Life and Changes in EEG and Sleep

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Tove Hallböök; Lunds universitet.; Lund University.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; vagus nerve stimulation; Neurologi; neurophysiology; neuropsychology; Neurology; Medicin människa och djur ; Medicine human and vertebrates ; behaviour; attention; ketogenic diet; delta power; slow wave sleep; REM; mood; sleep; quality of life; EEG; seizure frequency; spike detection; children; neurofysiologi; Pediatri; epilepsy; Pediatrics;

    Abstract : When anti-epileptic drugs fail, and epilepsy surgery is found unfeasible or ineffective, there remains a group of at least 25% of children with epilepsy in whom seizure control cannot be achieved. Vagus nerve stimulation (VNS) is an adjunctive treatment for medically refractory epilepsy. READ MORE

  2. 2. A Signal Processing Approach to Practical Neurophysiology A Search for Improved Methods in Clinical Routine and Research

    University dissertation from Uppsala : Signals and Systems

    Author : Björn Hammarberg; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; matched filter; asynchronous detection; Kalman filter; initialization; MHT; Wiener deconvolution; line source model; electromyography; needle EMG; motor unit potential; MUAP; mean fiber concentration; jitter; microneurography; C-fiber; spike sorting; Systemteknik; TECHNOLOGY Information technology Systems engineering; TEKNIKVETENSKAP Informationsteknik Systemteknik; Signal Processing; signalbehandling;

    Abstract : Signal processing within the neurophysiological field is challenging and requires short processing time and reliable results. In this thesis, three main problems are considered.First, a modified line source model for simulation of muscle action potentials (APs) is presented. READ MORE

  3. 3. Speciation analysis of butyl- and phenyltin compounds in environmental samples by GC separation and atomic spectrometric detection

    University dissertation from Umeå : Kemi

    Author : Dong Nguyen Van; Umeå universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organotin speciation analysis; species-specific isotope dilution; inductively coupled plasma mass spectrometry; single isotope spike; multi-isotope spike; redistribution; species transformation; preparative liquid chromatography; gas chromatography; line source atomic absorption spectrometry; continuum source atomic absorption spectrometry; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi;

    Abstract : The main goal of the work presented in this thesis is to improve the reliability of existing methods for speciation analysis of organotin compoundsSpecies-specific isotope dilution (SSID) calibration in combination with gas chromatography – inductively coupled plasma mass spectrometry was used to investigate the transformation of phenyltin species during sample preparation. Isotope-enriched phenyltin species were synthesized from corresponding isotope-enriched tin metals. READ MORE

  4. 4. Oscillations and spike statistics in biophysical attractor networks

    University dissertation from Stockholm : Numerical Analysis and Computer Science (NADA), Stockholm Univeristy

    Author : Mikael Lundqvist; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attractor networks; computational neuroscience; cortex; datalogi; Computer Science;

    Abstract : The work of this thesis concerns how cortical memories are stored and retrieved. In particular, large-scale simulations are used to investigate the extent to which associative attractor theory is compliant with known physiology and in vivo dynamics. READ MORE

  5. 5. Information processing in the Striatum a computational study

    University dissertation from Stockholm : KTH

    Author : Johannes Hjorth; KTH.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; striatum; fast spiking interneuron; gap junctions; synchronisation; up-state detection; CaMKII; mathematical modelling; MEDICINE Morphology; cell biology; pathology Cell biology Neuroscience; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi Neurovetenskap;

    Abstract : The basal ganglia form an important structure centrally placed in the brain. They receive input from motor, associative and limbic areas, and produce output mainly to the thalamus and the brain stem. The basal ganglia have been implied in cognitive and motor functions. READ MORE
