  2. 1. Machine learning for identification of brain activity patterns with applications in gentle touch processing

    Author : Malin Björnsdotter Åberg; Göteborgs universitet; []
    Keywords : Somatosensory; Machine learning; Pattern recognition; fMRI; Support vector machines; Neuroscience; Brain; BOLD; Signal processing; Artificial intelligence; Touch; Human; Unmyelinated; Sensory; Affective;

    Abstract : Since the first mention of artificial intelligence in the 1950s, the field of machine learning has provided increasingly appealing tools for recognition of otherwise unintelligible pattern representations in complex data structures. Human brain activity, acquired using functional magnetic resonance imaging (fMRI), is a prime example of such complex data where the utility of pattern recognition has been demonstrated in a wide range of studies recently (Haynes et al.

  4. 2. Itch and Pain Inhibitory Mechanisms in Humans - evidence for a differential control of nociceptive senses

    Author : Hans-Jörgen Nilsson; Neurofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; Human; TENS; Somatosensory; Pruritus; Analgesia; Pain; Nociception; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : It is known that stimulation of thin nerve afferents can inhibit itch and pain and that the nociceptive systems have a detailed topographical organisation, with subsystems exhibiting specific excitatory and inhibitory receptive fields. On this basis, a new technique was developed, termed Cutaneous Field Stimulation (CFS), that electrically stimulates thin nerve fibers innervating specific skin fields. READ MORE

  5. 3. Spontaneous Movements during Sleep Guide Spinal Self-organization: Formation and Expression of a Memory Trace

    Author : Per Petersson; Neurofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neuropsychology; Neurology; long-term memory; somatosensory; receptive field; learning; sensorimotor; developmental; neurophysiology; neurofysiologi; neuropsykologi;

    Abstract : During development, information about the three-dimensional shape and mechanical properties of the body is laid down in the synaptic connectivity of sensorimotor systems through adaptive mechanisms. In spinal reflex systems, this enables the fast transformation of complex sensory information into adequate correction of movements. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Analysis of Adaptation in Human Postural Control

    Author : Per-Anders Fransson; Lund näs- och halssjukdomar Öron-; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical medicine; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ; Adaptation; Postural control; Proprioception; Vestibular; Posturography; neuropsykologi; Neurologi; neurophysiology; neuropsychology; Neurology; hörsel- och talorganen; audiologi; Otorinolaryngologi; auditive system and speech; audiology; Otorhinolaryngology; Movement pattern; Sensorimotor integration; Muscle fatigue; Age; Cutaneous sensation; neurofysiologi;

    Abstract : The ability to obtain correct balance control information and adjust motor performance appropriately are essential elements in effective postural control. However, functional disorders may affect the reliability of receptor information and ability to carry out corrective motions needed to maintain balance. READ MORE
