Advances in research on the neurological and neuropsychiatric phenotype of Klinefelter syndromeIvanka Savic
Department of Clinical Neuroscience, Karolinska Institute, Solna, Stockholm, Sweden
Curr Opin Neurol 25:138-43. 2012..The aim of this review is to combine available brain imaging and behavioral data to provide an overview of what we have learned about the neural underpinnings of cognitive, emotional and behavioral dysunctions in Klinefelter syndrome...
Pheromone signal transduction in humans: what can be learned from olfactory lossIvanka Savic
Stockholm Brain Institute, Department of Clinical Neuroscience, Karolinska University Hospital, MR Centre, Sweden
Hum Brain Mapp 30:3057-65. 2009..The anosmics inability to activate the hypothalamus with EST, therefore, suggests that in healthy men EST signals were primarily transmitted via the olfactory system...
PET and MRI show differences in cerebral asymmetry and functional connectivity between homo- and heterosexual subjectsIvanka Savic
Stockholm Brain Institute, Department of Clinical Neuroscience, Karolinska Institute, 171 76 Stockholm, Sweden
Proc Natl Acad Sci U S A 105:9403-8. 2008..The present study shows sex-atypical cerebral asymmetry and functional connections in homosexual subjects. The results cannot be primarily ascribed to learned effects, and they suggest a linkage to neurobiological entities...
Sex dimorphism of the brain in male-to-female transsexualsIvanka Savic
Stockholm Brain Institute, Department of Clinical Neuroscience, Karolinska Institute, Stockholm, Sweden
Cereb Cortex 21:2525-33. 2011..The present data do not support the notion that brains of MtF-TR are feminized. The observed changes in MtF-TR bring attention to the networks inferred in processing of body perception...
Androstenol--a steroid derived odor activates the hypothalamus in womenIvanka Savic
Stockholm Brain Institute, Karolinska Institutet, Department of Clinical Neuroscience, Stockholm, Sweden
PLoS ONE 5:e8651. 2010..A further issue was to evaluate whether the pattern of activation resembles the pattern of common odors...
Imaging of odor perception delineates functional disintegration of the limbic circuits in mesial temporal lobe epilepsyCarolina Ciumas
Department of Clinical Neuroscience, Division of Neurology, Karolinska University Hospital, Karolinska Institutet, Sweden
Neuroimage 39:578-92. 2008..It shows an altered response in several regions, which may underlie some interictal behavioral problems associated with this condition...
Passive perception of odors and semantic circuitsIvanka Savic
Department of Neuroscience, Karolinska Institute, Stockholm, Sweden
Hum Brain Mapp 21:271-8. 2004..Already the most elemental form of odor processing, passive perception thus seems to engage semantic circuits. This is achieved by the ability of odorants to immediately elicit associations and judgments of odor characteristics...
Odor processing in multiple chemical sensitivityLena Hillert
Department of Public Health Sciences, Division of Occupational Medicine, Karolinska Institutet, Stockholm, Sweden
Hum Brain Mapp 28:172-82. 2007..One possible explanation for the observed pattern of activation in MCS is a top-down regulation of odor-response via cingulate cortex...
Brain imaging studies of the functional organization of human olfactionIvanka Savic
Department of Neuroscience, Division of Human Brain Mapping, Karolinska Institute, Stockholm, Sweden
Chem Senses 30:i222-3. 2005
Brain response to putative pheromones in lesbian womenHans Berglund
Department of Medicine, and Stockholm Brain Institute, Karolinska University Hospital, Karolinska Institutet, 171 76 Stockholm, Sweden
Proc Natl Acad Sci U S A 103:8269-74. 2006..These data support our previous results about differentiated processing of pheromone-like stimuli in humans and further strengthen the notion of a coupling between hypothalamic neuronal circuits and sexual preferences...
Imaging of brain activation by odorants in humansIvanka Savic
Department of Neuroscience, Karolinska Institute, Retziusvag 8, 17177, Stockholm, Sweden
Curr Opin Neurobiol 12:455-61. 2002....
Brain response to putative pheromones in homosexual menIvanka Savic
Department of Clinical Neuroscience, Karolinska University Hospital, 171 76 Stockholm, Sweden
Proc Natl Acad Sci U S A 102:7356-61. 2005..These findings show that our brain reacts differently to the two putative pheromones compared with common odors, and suggest a link between sexual orientation and hypothalamic neuronal processes...
The dopamine system in idiopathic generalized epilepsies: identification of syndrome-related changesCarolina Ciumas
Stockholm Brain Institute, and Department of Clinical Neuroscience, Karolinska Institutet, Sweden
Neuroimage 51:606-15. 2010..The present data suggest that the two forms of IGE have different neuronal substrates...
Quantitative PET analyses of regional [11C]PE2I binding to the dopamine transporter--application to juvenile myoclonic epilepsyIkuo Odano
Psychiatric Section, Department of Clinical Neuroscience Karolinska Institutet, Stockholm, Sweden
Neuroimage 59:3582-93. 2012..The reference tissue models should be applied with better understanding of the biochemical nature of the radioligand and the reliability of these approaches...
Migraine and olfactory stimuliChristina Sjöstrand
Headache Research Centre, Department of Clinical Neuroscience, Karolinska Institutet, Karolinska University Hospital Huddinge, Stockholm, Sweden
Curr Pain Headache Rep 14:244-51. 2010..Migraine pathophysiology likely explains this particular vulnerability. We discuss these pathophysiologic mechanisms and hypotheses relating odour intolerances and migraine...
Brain imaging studies of the functional organization of human olfactionIvanka Savic
Department of Neuroscience, Karolinska Institute, Stockholm, Sweden
Neuroscientist 8:204-11. 2002..New data from brain imaging studies suggest that this is not the case and that the specific characteristics of the sense of smell can be attributed to the engagement of limbic structures at an early stage in the signal processing...
Odorant differentiated pattern of cerebral activation: comparison of acetone and vanillinIvanka Savic
Division of Human Brain Research, Department of Neuroscience, Karolinska Institute, Stockholm, Sweden
Hum Brain Mapp 17:17-27. 2002..Acetone's limited activation of the olfactory cortex may result from a cross-modal interaction, with inhibition of acetone's odor component by its trigeminal component...
