  1. 1. Hemocytes and neural injury in freshwater crayfish : Does the melanization reaction matter?

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Amanda Gustafsson; [2022]
    Keywords : Melanization; neural injury; freshwater crayfish; Melanisering; nervskada; sötvattenskräfta;

    Abstract : Neurogenesis primarily occurs during embryonic development in decapod crustaceans, ending when the embryonic precursor cells die. However, areas in the central olfactory pathway are exceptions to this. Here, neurons are produced throughout the animal’s life from precursor cells in the neurogenic niche. READ MORE

  3. 2. Emotional resilience in humans as an effect of hippocampal pattern separation

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Thomas Wahlund; [2021]
    Keywords : Pattern separation; adult neurogenesis; mnemonic similarity task; anxiety; fear generalization;

    Abstract : Pattern separation is the means by which the brain discriminates similar experiences. It enables retrieval of individuated memories without confusing them with other memories. It is the reason one remembers where one parked the car today and does not mix it up with where one parked it previously. READ MORE

  4. 3. Exercise-induced adult hippocampal neurogenesis and the effect of exercise and adult hippocampal neurogenesis on spatial learning and memory

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : André Sturesson; [2018]
    Keywords : adult hippocampal neurogenesis; AHN; exercise; exercise-induced AHN; spatial learning and memory;

    Abstract : It was long believed within the scientific community that the adult brain was unable to generate new neurons. In the end of the 1990s the consensus changed and it is since believed that the adult brain can and does generate new neurons after birth, a process referred to as adult neurogenesis. READ MORE

  5. 4. Increased expression, but not insertion of L1 retrotransposons in aged neural stem and progenitor cells

    University essay from Lunds universitet/Tillämpad biokemi

    Author : Jonas Fritze; [2015]
    Keywords : Retrotransposons; Aging; Neural Stem Cells; LINE1; APOBEC3; Medicine and Health Sciences;

    Abstract : Retrotransposons are mobile elements that build up an extensive part of our genome, and can create genomic instability through new insertions. LINE1 is a subtype of transposons that are still active in human and mice, and can both copy themselves, and assist other retroelements to new insertions, but are strongly regulated by different enzymes.

  6. 5. Higher depression scores are associated with lower pattern separation performance in humans

    University essay from Lunds universitet/Institutionen för psykologi

    Author : Arina Semenova; [2015]
    Keywords : depression; pattern separation; memory interference; recognition memory; BPS-O; neurogenesis; hippocampus; dentate gyrus; gender; gender-difference; Medicine and Health Sciences; Social Sciences;

    Abstract : Memory impairment has been connected to depression, however this association appears complex. Pattern separation is a specific hippocampal function, which separates similar events and stimuli into distinct memory representations. Hippocampal volume reduction has been seen in individuals suffering from depression. READ MORE
