  2. 1. Lateralization of human olfaction : cognitive functions and electrophysiology

    Author : Daniel Broman; Steven Nordin; Matthias Laska; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human olfaction; Laterality; Olfactory processes; Odor familiarity; Odor identification; OERP; Psychology; Psykologi;

    Abstract : In this thesis lateralization of olfactory functions was investigated by both behavioral and electrophysiological assessment, the latter with the olfactory event-related potential (OERP) technique. The olfactory sense is primarily ipsilateral in that a stimulus that is presented to one nostril is initially processed in the same hemisphere. READ MORE

  4. 2. BMP - a key signaling molecule in specification and morphogenesis of sensory structures

    Author : Vijay Kumar Jidigam; Lena Gunhaga; Jonas von Hofsten; Richard A. Lang; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BMP signaling; Placode morphogenesis; lens; retina; olfactory; otic; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : Cranial placodes are transient thickenings of the vertebrate embryonic head ectoderm that will give rise to sensory (olfactory, lens, and otic) and non-sensory (hypophyseal) components of the peripheral nervous system (PNS). In most vertebrate embryos, these four sensory placodes undergo invagination. READ MORE

  5. 3. Modeling prediction and pattern recognition in the early visual and olfactory systems

    Author : Bernhard Kaplan; Lansner Anders; Fred Hamker; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spiking neural networks; pattern recognition; self-organization; prediction; anticipation; visual system; olfactory system; modeling; Computer Science; Datalogi;

    Abstract : Our senses are our mind's window to the outside world and determine how we perceive our environment.Sensory systems are complex multi-level systems that have to solve a multitude of tasks that allow us to understand our surroundings. READ MORE

  6. 4. Early development of the olfactory placode and early rostrocaudal patterning of the caudal neural tube

    Author : Esther Maier; Lena Gunhaga; Fernando Giraldez; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; olfactory placode; caudal neural tube; Wnt; FGF; RA; BMP; Notch; patterning; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The development of the nervous system is a complex process. Cell divisions, cell differentiation and signalling interactions must be tightly regulated. To comprehend the mature nervous system, we have to understand its assembly during development. READ MORE

  7. 5. The Role of miRNA in Neurogenesis and Cell Specification

    Author : Malin Åkerblom; Molekylär neurogenetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; miRNA; microRNA; miR-124; miR-9; miR-125; adult neurogenesis; neural stem cells; cell specification; microglia; lentiviral vectors; olfactory bulb; olfactory bulb interneurons;

    Abstract : Only a few decades ago, it was generally believed that gene expression was controlled in a unidirectional way, i.e. DNA was transcribed into RNA, which simply acted as a messenger molecule used to produce the protein that executed cellular functions. READ MORE
