  1. 1. Early Rostrocaudal Patterning of the CNS

    Författare :Ulrika Nordström; Thomas Edlund; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CNS development; neural patterning; neural specification; Wnt; FGF; RA; Isthmic organizer; motor neurons; rostrocaudal patterning.; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : The transformation of an initially uniform population of epiblast cells into an intricately complex central nervous system (CNS) is one of the most fascinating processes during embryonic development. Presumptive neural cells are initially specified as cells of forebrain character. LÄS MER

  3. 2. Cerebellar pathways and mechanisms in classical conditioning

    Författare :Pär Svensson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; Climbing Fibers; Conditioned Response; Mossy Fibers; Ferret; Eyeblink; Cerebellum; Classical Conditioning; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : It has been suggested that the cerebellar mossy fibre afferents transmit the conditioned stimulus (CS) information to the cerebellum. Several studies are consistent with this suggestion but alternative explanations have not been excluded. LÄS MER

  4. 3. Severe Head Injury. Evaluation of Acute Treatment and Rehabilitation

    Författare :Christer Eker; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neuropsykologi; neurofysiologi; cerebral blood flow; neuropsychological test; assessment of motor and process skills; rehabilitation; Neurology; neuropsychology; neurophysiology; intracranial pressure; Severe head injury; intensive care;

    Sammanfattning : Mortality after severe head injury can be considerably reduce with a therapy using physiological principles for brain volume regulation and preserved microcirculation, with the main purpose of restricting the rise in ICP to reasonable levels simultaneously with preservation of adequate blood supply. This study shows that the ?Lund Concept? can reduce mortality in patients with severe traumatic brain lesions from 47% to 8%. LÄS MER

  5. 4. Quantitative Magnetic Resonance Imaging of the Brain : Applications for Tissue Segmentation and Multiple Sclerosis

    Författare :Janne West; Peter Lundberg; Anne-Marie Landtblom; Marcel Jan Bertus Warntjes; Örjan Smedby; Olof Dahlqvist Leinhard; Per Thunberg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Magnetic resonance imaging (MRI) is a sensitive technique for assessing white matter (WM) lesions in multiple sclerosis (MS), but there is a low correlation between MRI findings and clinical disability. Because of this, other pathological changes are of interest, including changes in normal appearing white matter (NAWM) and diffusely abnormal white matter (DAWM). LÄS MER

  7. 5. Immunocytochemical studies of excitatory amino acid neurotransmitters and transporters in the spinal cord and nucleus submedius

    Författare :Stefan Persson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurophysiology; neuropsychology; Neurology; VGLUT2; VGLUT1; pain; somatosensory; thalamus; immunogold; glutamate; aspartate; dorsal horn; excitatory amino acids; spinal cord; neurofysiologi; Neurologi;

    Sammanfattning : The amino acid glutamate is today regarded as the main fast excitatory neurotransmitter in the central nervous system and a large body of evidence support that glutamate serves as a neurotransmitter in primary afferent terminals in the spinal cord. Previous evidence also suggests that the closely related amino acid aspartate may serve a similar role in some primary afferent terminals. LÄS MER
