  2. 11. Keeping Eye and Mind on the Road

    Author : Trent Victor; Claes von Hofsten; John Wann; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Vision; Eye-movements; Driving; Attention; Distraction; Ventral stream; Dorsal stream; Road safety; Traffic crashes; Evaluation methodology; Psykologi; Psychology; Psykologi;

    Abstract : This thesis is devoted to understanding and counteracting the primary contributing factor in traffic crashes: inattention. Foremost, it demonstrates the fundamental importance of proactive gaze in the road centre area for action guidance in driving. READ MORE

  4. 12. Stem cell function and organ development : analysis of Lhx2 function in hematopoietic stem cells and eye development

    Author : Lina Dahl; Leif Carlsson; Jan-Ingvar Jönsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Abstract : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. READ MORE

  5. 13. Characterisation of nystagmus waveforms in eye-tracker signals

    Author : William Rosengren; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Eye tracking; Signal processing; Nystagmus;

    Abstract : This thesis deals with the analysis of eye–tracker signals recorded from nystagmus patients. Nystagmus is an eye movement disorder caused by an underlying condition, and patients who suffer from nystagmus express involuntary oscillating eye move- ments. READ MORE

  6. 14. Visual ecology of insect superposition eyes

    Author : Pär A Brännström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal physiology; tiger beetle; hawkmoth; mayfly; insect; visual ecology; eye design; vision; compound eye; Djurfysiologi;

    Abstract : In the superposition compound eye each rhabdom (light sensitive unit) receives light through many ommatidial facets, while in the apposition compound eye every rhabdom receives light from a single facet. The superposition design increases photon capture, which is an advantage in dark environments. READ MORE

  7. 15. Comparative optics of prosobranch eyes

    Author : Jan-Olof Seyer; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ampularia; Littorina; Strombus; evolution; visual ecology; summation; convergence; optic nerve; resolution; sensitivity; optics; eye; gastropod; prosobranch; Animal anatomy; animal morphology; Djurs anatomi och morfologi;

    Abstract : Functional aspects of the large diversity of eye design in prosobranch molluscs was investigated using morphological and optical methods. Three species from different habitats were investigated. Littorina littorea from Scandinavian intertidal rock habitats, Strombus raninus and S. gigas from tropical sand-flats and Ampularia sp.
