  2. 1. Radiological Studies on Hippocampal Development : Morphological Variants and their Relationship to Epilepsy

    Author : Dragan Bajic; Raili Raininko; Kai Ericson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; Brain development; Hippocampus; Epilepsy; Radiology; Radiologi; Radiologi; Radiology;

    Abstract : During fetal development, the hippocampal structures are folded forming the hippocampal sulcus which penetrates into the temporal lobe and then the entity rotates.  During this process, the hippocampal sulcus will be closed and the inverted hippocampus takes a rounded form.

  4. 2. 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.

  5. 3. Hippocampal circuit dynamics in learning and value processing of sensory cues : A study into the function of hippocampal microcircuits involving OLMα2 cells

    Author : Samer Siwani; Klas Kullander; Michael Hasselmo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The anatomical signatures of the mnemonic/emotional processes share many brain structures, one of which seems to constitute a bridge, the hippocampus. It functions as a structure that consolidates engrams. It is connected to the prefrontal cortex, nucleus accumbens and amygdala, structures that provide emotional salience. READ MORE

  6. 4. Hippocampal volumetry in mild cognitive impairment

    Author : Carl Eckerström; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mild cognitive impairment; dementia; Alzheimer s disease; vascular dementia; MRI; hippocampus; white matter lesions; CFS biomarkers; neuropsychology;

    Abstract : Dementia is a syndrome with cognitive decline as a prominent feature. MCI is similarly a syndrome of cognitive decline, albeit with much subtler symptoms, and has been identified as a condition at risk for progression to dementia. A considerable clinical challenge lies in identifying MCI patients with an underlying dementia disorder. READ MORE

  7. 5. Intraocular and intracranial transplantation of neural tissue : Studies on hypothalamic and hippocampal neuros

    Author : Hanna Bergman; Pertti Panula; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Previous studies has demonstrated the possibility to transplant monoaminergic neurons intracranially and to the anterior chamber of the eye, where these neurons continue to develop into functional, transmitter expressing cells. In the present study, investigations were undertaken to examine the development of transplanted hypothalamic and hippocampal neurons in the rat. READ MORE
