1. 1. fMRI for mapping the plastic somatotopy of primary somatosensory cortex - Development and clinical applications

   Författare :Andreas Weibull; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smoothing; physiological noise; spatial resolution; primary somatosensory cortex; cortical reorganisation; brain plasticity; fMRI; partial volume effects;

   Sammanfattning : Functional magnetic resonance imaging (fMRI) is a widely used tool for studying brain function in vivo. The technique is based on acquiring brain images sensitive to the physiological response following neural activation, and hence, allows brain activity to be examined and documented. LÄS MER

3. 2. Self-Organizing Body Maps in the Spinal Cord

   Författare :Marcus Granmo; Neurofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; somatosensory; learning; development; cortex; spinal cord; activity dependent; pain; plasticity;

   Sammanfattning : During development primary afferents grow into and establish neuronal connections in the spinal cord, conveying information of the anatomical and mechanical properties of the body. This body representation forms the basis for how we perceive sensory information and control our movements. LÄS MER

4. 3. Somatosensory Circuits in the Central Nervous System

   Författare :Hannah M. Weman; Malin C. Lagerström; Sarah E. Ross; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glycine receptor alpha 3; urocortin 3; vesicular monoaminergic transporter 2; nociception; pruriception; spinal cord; somatosensory cortex; DREADD; rabies tracing; transcriptomics; Neuroscience; Neurovetenskap;

   Sammanfattning : Spinal glycinergic neurons prevent spontaneous sensations of pain and itch, and development of persistent pain and itch conditions. The glycine receptor alpha 3 subunit (GLRA3) is suggested to be involved in certain inflammatory models, but not in acute nociception. LÄS MER

5. 4. 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

7. 5. A tailored biocompatible neural interface for long term monitoring in neural networks

   Författare :Per Köhler; Neuronano Research Center (NRC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-machine interfaces; neuroinflammation; somatosensory cortex; hyperalgesia; allodynia;

   Sammanfattning : Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. LÄS MER
