1. 1. Sensorimotor transformations during grasping movements

   Författare :Daniel Säfström; Benoni B. Edin; Melvyn A. Goodale; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sensorimotor transformation; sensory integration; visuomotor map; human physiology; adaptation; grasping; sensory substitution; Physiology; Fysiologi;

   Sammanfattning : ‘Sensorimotor transformations’ are processes whereby sensory information is used to generate motor commands. One example is the ‘visuomotor map’ that transforms visual information about objects to motor commands that activates various muscles during grasping movements. LÄS MER

3. 2. On sensory feedback in hand prostheses

   Författare :Christian Antfolk; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prosthetic hands; sensory feedback.;

   Sammanfattning : Amputation of the hand implies the loss of the ability to grasp and the ability to "feel". The grasping function can be primitively restored using an active prosthesis. Multi­articulating electrically powered hands have recently made their way to the market and these hands provide enhanced grasping and gripping capabilities. LÄS MER

4. 3. Identification of subgroups in experimental and chronic pain : Sensory, emotional and evaluative aspects

   Författare :Ragnhild Raak; Bengt H. Sjölund; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : One hundred and two healthy subjects, 32 fibromyalgia patients and 12 chronic low back pain patients were included in the study. Quantitative sensory tests were performed to identify thermal hyperalgesia in the fibromyalgia group and to compare the results with those in healthy pain-free subjects. LÄS MER

5. 4. Vitamin A regulated neuronal regeneration and homeostasis

   Författare :Sofia Håglin; Anna Berghard; Staffan Bohm; Leif Carlsson; Ola Hermanson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Activity dependent; Adult stem cells; Ageing; CYP26B1; Homeostasis; Metaplasia; Neurogenesis; Olfactory epithelium; Regeneration; Respiratory epithelium; Retinoic acid; Sensory map; Vitamin A;

   Sammanfattning : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. LÄS MER

7. 5. Towards a tactile artifical hand

   Författare :Ulrika Wijk; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amputation; upper limb; phantom hand map; sensory feedback; referred sensation; hand prosthesis; body ownership; tactile sensation;

   Sammanfattning : Amputation of a hand is a life-changing event, and the loss of motor and sensory functions leads to disability and has devastating effects on the individual. What is normally performed using two hands must be solved with only one, and the loss also affects body balance and body posture. LÄS MER
