  1. 1. Mass Spectrometry-based Neuroproteomics Deciphering the Human Brain Proteome

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sravani Musunuri; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brain; Proteomics; Mass spectrometry; Alzheimer s disease; Traumatic brain injury; Membrane proteins; Sample preparation; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Abstract : Mammalian brain is challenging to study due to its heterogeneity and complexity. However, recent advances in molecular imaging, genomics and proteomics have contributed significantly to achieve insights into molecular basis of brain function and pathogenesis of neurological disorders.

  2. 2. Dietary L-Tryptophan Suppresses Aggression and Stress Responsiveness in Juvenile Rainbow Trout (Oncorhynchus mykiss) The Role of Brain Serotonin and Plasma Melatonin

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Olivier Lepage; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; serotonin; brain; fish; rainbow trout; Oncorhynchus mykiss; feed; stress; cortisol; melatonin; behaviour; aggression; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : Juvenile rainbow trout (Oncorhynchus mykiss) fed L-tryptophan (TRP) supplemented feed for 7 days show a suppression of aggressive behaviour along with a reduction in post-stress plasma cortisol levels. However, 3 days of elevated dietary TRP does not have any effects on either aggressive behaviour or post-stress plasma cortisol levels. READ MORE

  3. 3. Segmentation and Visualisation of Human Brain Structures

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Roger Hult; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; segmentation; visualisation; brain; cortex; hippocampus; autoradiography; MRI; PET; ROI; Bildanalys; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Abstract : In this thesis the focus is mainly on the development of segmentation techniques for human brain structures and of the visualisation of such structures. The images of the brain are both anatomical images (magnet resonance imaging (MRI) and autoradigraphy) and functional images that show blood flow (functional magnetic imaging (fMRI), positron emission tomography (PET), and single photon emission tomograpy (SPECT)).

  4. 4. Why and how brain size evolves Sociality, predation and allometry

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Wouter van der Bijl; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; brain size; brain size evolution; encephalization; predation; predator inspection; sociality; animal contest; constraint; etologi; Ethology;

    Abstract : The evolution of the vertebrate brain has remained a topic of intense interest from biologists over many decades. Evolutionary biologists have seen it as an intriguing example of how the size and structure of a trait evolves across large phylogenies and under body size constraints, with both large shifts in deep evolutionary time and continuous smaller scale adaptation.

  5. 5. Reality-based brain-computer interaction

    University dissertation from Umeå : Department of Computing Science, Umeå University

    Author : Daniel Sjölie; Umeå universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reality-based brain-computer interaction; virtual reality; reality-based interaction; brain-computer interface; activity theory; the free-energy principle; grounded cognition; TECHNOLOGY Information technology Computer science Cognitive science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Kognitionsvetenskap; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi; människa-datorinteraktion; människa-datorinteraktion;

    Abstract : Recent developments within human-computer interaction (HCI) and cognitive neuroscience have come together to motivate and enable a framework for HCI with a solid basis in brain function and human reality. Human cognition is increasingly considered to be critically related to the development of human capabilities in the everyday environment (reality). READ MORE
