  1. 1. Liksom ett par nya ögon. Frithiof Holmgren och synsinnets problematik

    Författare :Jan-Eric Olsén; Avdelningen för idé- och lärdomshistoria; []
    Nyckelord :HUMANIORA; HUMANITIES; history of ideas; History of philosophy; vivisections; colour perception; colour-blindness; the visual organ; the human body; sensations; scientific ideals; industrial technology; Frithiof Holmgren; scientific instruments; physiological experiments; laboratory medicine; physiology; Filosofins historia; idéhistoria; History of science; Vetenskapshistoria;

    Sammanfattning : This study deals with research on the visual organ as pursued in experimental physiology during the latter half of the nineteenth-century. In the 1850's och 60's experimental physiology developed as a new, scientific discipline within the curriculum of western medicine. LÄS MER

  2. 2. Ephrins off the beaten path

    Författare :Johan Holmberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The Orchestration of cell-cell interactions is crucial to the developing embryo and the adult organism. Intercellular communication is to a large extent controlled by signalling events downstream of receptor tyrosine kinases (RTKs). Ligands for RTKs are often soluble and confer long distance information to the receptor expressing cell. LÄS MER

  3. 3. Physical measurements and subjective characterization of pipe organ mechanical key actions

    Författare :Erkin Asutay; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical key action; Pipe organ; Instrument – player interaction;

    Sammanfattning : Musical instruments do not only provide auditory or visual information but they also convey haptic feedback to the performer. One might consider that the auditory feedback is the only crucial information that the musician requires. LÄS MER

  4. 4. How the sensory ecology of the bumblebee affects their functional traits

    Författare :Vun Wen Jie; Emily Baird; Mikael Carlsson; Martin How; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bumblebee; functional morphological traits; intraspecific differences; allometry; DRA; micro-CT; co-existence; Functional Zoomorphology; funktionell zoomorfologi;

    Sammanfattning : Morphological traits are important for trait-based ecological studies as they allow for the prediction of biodiversity across the biosphere. Currently, the predictive power of trait-based ecology is not often applied to terrestrial arthropods, even though they provide us with important agricultural, ecological, and cultural value.

  5. 5. The optic tectum of the salmon:site of interaction of neurohormonal photoperiodic and neural visual signals. The GABAergic neuronal system and melatonin receptors

    Författare :Marie Anzelius; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal anatomy; melatonin receptors; GABA; optic tectum; fish; brain; animal morphology; Djurs anatomi och morfologi;

    Sammanfattning : Melatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. LÄS MER
