  2. 1. Development of central catecholaminergic neuronal systems in the lizard Anolis sagrei

    Author : Agneta Rehn; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; double labelling; immunohistochemistry; interplexiform cells; amacrine cells; catecholamines; development; retina; Reptiles; brain; Zoology; Zoologi;

    Abstract : Catecholamines, comprising the neurotransmitters dopamine (DA), noradrenaline (NA) and adrenaline (A) are synthesized by specific enzymes (tyrosine hydroxylase (TH), dopamine ß-hydroxylase (DBH), phenylethanolamine-N-methyltransferase (PNMT)) in the central nervous system. The development and distribution of different catecholaminergic systems have been described in both the brain and retina of the lizard Anolis sagrei. READ MORE

  4. 2. Generation of Retinal Neurons : Focus on the Proliferation and Differentiation of the Horizontal Cells and their Subtypes

    Author : Henrik Boije; Finn Hallböök; Paul Layer; Uppsala universitet; []

    Abstract : We have used the chicken retina as a model for investigating cell cycle regulation and cell fate commitment during central nervous system development. This thesis focuses on the characterization of and commitment to the horizontal cell fate in the retina. READ MORE

  5. 3. Neurotrophic factors and their receptors in the developing avian retina and its tectal target

    Author : Miriam Karlsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neurovetenskap; Neurology; Neurologi; Developmental Neurosciences; medicinsk utvecklings- och neurobiologi;

    Abstract : Neurotrophic factors and their receptors are crucial for the formation of neuronal connections and for the neuronal survival during embryonic development of the nervous system. This has particularly been shown by studies of the PNS. READ MORE
