  1. 1. 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

  2. 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

  3. 3. Targeting and driving somatosensory neurons

    Författare :Fabio Freitag; Malin C. Lagerström; Andrew Todd; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pain; Itch; GRPR interneurons; dorsal horn; trigeminal nucleus caudalis; Barrel field;

    Sammanfattning : Pain and itch are two distinct sensations, but the fundamental question of how our nervous system distinguishes the processing and encoding of their related information is still far to be clearly delineated. At the spinal cord level, evidences have pointed out specific groups of neurons expressing the gastrin releasing peptide (Grp) and its receptor (Grpr) as responsible for carrying specifically itch-related information.

  4. 4. Information Processing in the Nervous System. On a Holistic Functional Organization Principle

    Författare :Jonas Enander; Hjärnans sensorimotoriska funktioner; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Somatosensory; Tactile; Neuron; Neocortex; Brain organization; Cortical functional localization;

    Sammanfattning : This thesis is concerned with the nature of information processing in the nervous system. This issue has been investigated with animal experiments, using male Sprague–Dawley rats, and simulated touch generated by an artificial fingertip with neuromorphic tactile sensors. LÄS MER

  5. 5. NO PAIN, STILL GAIN- cross-modality development learning guided by spinal spontaneous activity

    Författare :Alexandra Waldenström Ellervik; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; Neurologi; Neurology; neuropsychology; development; spinal cord; activity-dependent learning and memory; pain; somatosensory; neurophysiology;

    Sammanfattning : Recent studies indicate that experience dependent mechanisms shape the pain system during the development. In view of that painful stimuli are rare during development it is not clear how this is accomplished. LÄS MER
