  1. 1. Making Head or Tail of the Hippocampus : A Long-Axis Account of Episodic and Spatial Memory

    Författare :Jonas Persson; Hedvig Söderlund; Tomas Furmark; Asaf Gilboa; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hippocampus; fMRI; episodic memory; spatial memory; gender differences; Psychology; Psykologi;

    Sammanfattning : While episodic and spatial memory both depend on the hippocampus, opposite gender differences in these functions suggest they are partly separate, with different neural underpinnings. The anterior and posterior hippocampus differ  in structure and whole-brain connectivity, and studies point to the posterior hippocampus being more involved in spatial memory while the anterior hippocampus’ role in episodic memory is less clear.

  3. 2. Genes to remember : imaging genetics of hippocampus-based memory functions

    Författare :Karolina Kauppi; Lars Nyberg; Jonas Persson; Guillén Fernández; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Imaging genetics; fMRI; Episodic memory; SNP; KIBRA; BDNF; APOE; Hippocampus; Parahippocampus;

    Sammanfattning : In the field of imaging genetics, brain function and structure are used as intermediate phenotypes between genes and cognition/diseases to validate and extend findings from behavioral genetics. In this thesis, three of the strongest candidate genes for episodic memory, KIBRA, BDNF, and APOE, were examined in relation to memory performance and hippocampal/parahippocampal fMRI blood-oxygen level-dependent (BOLD) signal.

  4. 3. Brain characteristics of memory decline and stability in aging : Contributions from longitudinal observations

    Författare :Sara Pudas; Jonas Persson; Lars Nyberg; Emrah Düzel; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; aging; episodic memory; individual differences; longitudinal assessment; magnetic resonance imaging; hippocampus; frontal cortex; Psychology; psykologi;

    Sammanfattning : Aging is typically associated with declining mental abilities, most prominent for some forms of memory. There are, however, large inter-individual differences within the older population. Some people experience rapid decline whereas others seem almost spared from any adverse effects of aging. LÄS MER
