  1. 6. Cerebellar Control of Classical Conditioning

    Författare :Magnus Ivarsson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Associative module; Bilateral; Orbicularis oculi muscle; Inferior olive; Purkinje cell; Eyeblink; Conditioned response; neuropsykologi; neurofysiologi; Neurologi; neurophysiology; neuropsychology; Neurology;

    Sammanfattning : It has previously been shown that the cerebellum is critical for classical conditioning. The experiments presented in this thesis aimed to study how the cerebellum controls conditioned eyeblink responses (CRs) and specifically the efferent path from the cerebellar cortex to the muscles.

  2. 7. Preterm intraventricular cerebral hemorrhage: role of cell-free hemoglobin

    Författare :Alex Adusei Agyemang; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intraventricular hemorrhage; Preterm birth; Haptoglobin; Alpha 1 microglobulin; cerebellar hypoplasia; periventricular white matter; cell-free hemoglobin;

    Sammanfattning : Cerebral intraventricular hemorrhage in preterm infants continues to be a major clinical problem associated with neurodevelopmental abnormalities manifested by cognitive, behavioral, attentional, social and motor deficits. Hypothesis and aims: The central thesis is that the cytotoxicity of extravasated blood and of consequently released cell-free hemoglobin(Hb) is pivotal for the pathophysiological events causally involved in brain injury.

  3. 8. Feedback control of cerebellar learning

    Författare :Anders Rasmussen; Associativ inlärning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; Rescorla-Wagner; Anticipation; In vivo Electrophysiology; Purkinje cells; Nucleo-Olivary inhibition; Inferior Olive; Classical Conditioning; Eyeblink Conditioning; Feedback;

    Sammanfattning : The ability to anticipate future events and to modify erroneous anticipatory actions is crucial for the survival of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. LÄS MER

  4. 9. Gastric Inhibitory Polypeptide in the brain

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

    Sammanfattning : 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. LÄS MER

  5. 10. Application of imaging TOF-SIMS in cell and tissue research

    Författare :Katrin Richter; Göteborgs universitet; []
    Nyckelord :TOF-SIMS; imaging mass spectrometry; cryopreparation; ions; lipids; galactosylceramide; sulfatide; fatty acids;

    Sammanfattning : This thesis is aimed at extending the use of TOF-SIMS (time of flight secondary ion mass spectrometry) as an analytical tool in cell and tissue research. TOF-SIMS is a relatively new method that allows analysis of the chemical composition of sample surfaces. LÄS MER
