  2. 11. Aging Along the Hippocampal Axis : Structure, Function and Whole-brain Connections in Association with Memory

    Author : Kristin Nordin; Hedvig Söderlund; Agneta Herlitz; Jessica Damoiseaux; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; hippocampus; aging; longitudinal-axis; episodic memory; spatial memory; connectivity; fMRI; Psychology; Psykologi;

    Abstract : Hippocampus-dependent functions display marked reductions in older age, an observation that has led to the extensive study of age effects on hippocampal properties. Even though research indicates that the hippocampus is structurally and functionally heterogeneous along its longitudinal axis, its anterior and posterior regions differentially supporting episodic and spatial memory representations, few studies explicitly consider age effects in relation to axis.

  4. 12. Gastric Inhibitory Polypeptide in the brain

    Author : Jenny Nyberg; Göteborgs universitet; []
    Keywords : neural progenitor cells; neural stem cells; hippocampus; cell proliferation; GIP; neuropeptides; insulinotropic; gastrointestinal;

    Abstract : The hippocampus is an area of active cell proliferation and neurogenesis within the adult mammalian brain. Adult neurogenesis is of great importance for the brain, since it increases neuroplasticity and the ability to respond to environmental stimuli. READ MORE

  5. 13. Food hoarding: Memory and social conditions - an evolutionary approach

    Author : Ken Lundborg; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Corvidae; Paridae; dominance rank; memory; food hoarding; foraging; hippocampus; birds; behavioural ecology;

    Abstract : Food hoarding is a widespread behavior among a large number of animals, and it exists in several different varieties, all of them used by the animals as a method of having a steady supply of food during periods of low food abundance such as the winter. This thesis concentrates mainly on two aspects of scatter food hoarding behavior, using small birds as study and model animals. READ MORE

  6. 14. Synaptic Integration of Hippocampal Neurons Generated in the Adult Brain: Influence of a Pathological Environment

    Author : Katherine Jakubs; Lund Neurologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; Neurologi; synaptic plasticity; GABA; glutamate; GFP; Neurology; neuropsychology; neurophysiology; hippocampus; dentate gyrus; neurogenesis; LPS; inflammation; epilepsy; SE; patch-clamp;

    Abstract : The adult brain constantly produces new neurons from endogenous neural progenitor cells located in at least two regions, the subgranular zone (SGZ) in dentate gyrus of the hippocampus, and the subventricular zone (SVZ). Major efforts are underway to discover the functional significance of new neurons in the adult brain. READ MORE

  7. 15. On the Mechanisms Behind Hippocampal Theta Oscillations : The role of OLMα2 interneurons

    Author : Sanja Mikulovic; Richardson Leao; Klas Kullander; Stefan Remy; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hippocampus; interneuron; optogenetics; theta oscillations; anxiety;

    Abstract : Theta activity is one of the most prominent rhythms in the brain and appears to be conserved among mammals.  These 4-12 Hz oscillations have been predominantly studied in the dorsal hippocampus where they are correlated with a broad range of voluntary and exploratory behaviors.
