1. 16. Acute toluene effects on neurotransmission in the central nervous system

   Författare :Karl Stengård; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :acetylcholine; aspartate; cerebellum; dopamine; GABA; globus pallidus; glutamate; microdialysis; rat; striatum; toluene; ;

   Sammanfattning : The aim of this thesis was to develop a method to study the effects of toluene in the central nervous system of the rat. Microdialysis on awake rats was used to study toluene's effects on the transmission of dopamine, acetylcholine, glutamate and aspartate in the striatum, and on GABA in the striatum, the cerebellum and the globus pallidus.

3. 17. The central cervical nucleus in the rat : studies on connectivity, function and chemical transmission

   Författare :Birger Ragnarson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Amino acid transmitter AMPA Anterograde Cerebellum Cervical Choleragenoid Electron microscopy Freeze-substitution Glutamate Horseradish peroxidase Ia primary afferent Immunogold Immunocytochemistry Locomotion Motoneuron NMDA Neck muscle Postembedding;

   Sammanfattning : The central cervical nucleus (CCN) is a spinocerebellar cell group in the upper cervical spinal cord (rat: Cl-C3), that is known to receive a powerful primary afferent input from, the upper cervical spinal nerves (C 1-C4), originating mainly from muscle spindle afferents in deep dorsal neck muscles and from the ipsi- and contralateral vestibular nuclei. It projects to the cerebellar vermis bilaterally and to all the vestibular nuclei contralaterally. LÄS MER

4. 18. Serotonergic mechanisms in atopic dermatitis

   Författare :Aram Rasul; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Atopic dermatitis (AD) may be worsened by stress and anxiety. Serotonin (5-hydroxytryptamine; 5-HT) is an important mediator in stress and anxiety. In the present thesis serotonergic mechanisms were studied in atopic dermatitis (AD). LÄS MER

5. 19. 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.

7. 20. 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.
