    Early removal of one eye reduces normally occurring cell death in the remaining eye (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-07-31
    Description: During normal development of the hamster eye, there is a substantial loss of cells from the retinal ganglion cell layer in the first two postnatal weeks. If one eye is lost at birth, this cell death is reduced in the remaining eye. This may account for the increased ipsilateral projection from this eye to the thalamus and midbrain observed in these animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sengelaub, D R -- Finlay, B L -- New York, N.Y. -- Science. 1981 Jul 31;213(4507):573-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244655" target="_blank"〉PubMed〈/a〉

    Androgens prevent normally occurring cell death in a sexually dimorphic spinal nucleus (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-08-16
    Description: The spinal nucleus of the bulbocavernosus (SNB) contains many more motoneurons in adult male rats than in females. Androgens establish this sex difference during a critical perinatal period, which coincides with normally occurring cell death in the SNB region. Sex differences in SNB motoneuron number arise primarily because motoneuron loss is greater in females than in males during the early postnatal period. Perinatal androgen treatment in females attenuates cell death in the SNB region, reducing motoneuron loss to levels typical of males. The results suggest that steroid hormones determine sex differences in neuron number by regulating normally occurring cell death and that the timing of this cell death may therefore define critical periods for steroid effects on neuron number.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nordeen, E J -- Nordeen, K W -- Sengelaub, D R -- Arnold, A P -- HD06478-02/HD/NICHD NIH HHS/ -- HD15021/HD/NICHD NIH HHS/ -- NS07355-01/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1985 Aug 16;229(4714):671-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4023706" target="_blank"〉PubMed〈/a〉

    Androgens regulate the dendritic length of mammalian motoneurons in adulthood (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-04-18
    Description: Sex steroid hormones have been thought to alter behaviors in adulthood by changing the activity of neural circuits rather than by inducing major structural changes in these pathways. In a group of androgen-sensitive motoneurons that mediate male copulatory functions, decreases in androgen levels after castration of adult rats produced dramatic structural changes, decreasing both the dendritic length and soma size of these motoneurons. These changes were reversed by androgen replacement. These results imply a surprising degree of synaptic plasticity in adult motoneurons and suggest that normal changes in androgen levels in adulthood are associated with significant alterations in the structure and function of these neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kurz, E M -- Sengelaub, D R -- Arnold, A P -- HD15021/HD/NICHD NIH HHS/ -- NS07355-02/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1986 Apr 18;232(4748):395-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3961488" target="_blank"〉PubMed〈/a〉
