    • Anatomical Alterations of the Visual Motion Processing Network in Migraine with and without Aura 

      Granziera, Cristina; DaSilva, Alexandre F. M; Snyder, Josh; Tuch, David S; May, Arne; Hadjikhani, Nouchine (Public Library of Science, 2006)
      Background: Patients suffering from migraine with aura (MWA) and migraine without aura (MWoA) show abnormalities in visual motion perception during and between attacks. Whether this represents the consequences of structural ...

    • Cortical hot spots and labyrinths: why cortical neuromodulation for episodic migraine with aura should be personalized 

      Dahlem, Markus A.; Schmidt, Bernd; Bojak, Ingo; Boie, Sebastian; Kneer, Frederike; Hadjikhani, Nouchine; Kurths, Jürgen (Frontiers Media S.A., 2015)
      Stimulation protocols for medical devices should be rationally designed. For episodic migraine with aura we outline model-based design strategies toward preventive and acute therapies using stereotactic cortical neuromodulation. ...

    • Differences in white matter reflect atypical developmental trajectory in autism: A Tract-based Spatial Statistics study☆ 

      Bakhtiari, Reyhaneh; Zürcher, Nicole R.; Rogier, Ophélie; Russo, Britt; Hippolyte, Loyse; Granziera, Cristina; Araabi, Babak Nadjar; Nili Ahmadabadi, Majid; Hadjikhani, Nouchine (Elsevier, 2012)
      Autism is a neurodevelopmental disorder in which white matter (WM) maturation is affected. We assessed WM integrity in 16 adolescents and 14 adults with high-functioning autism spectrum disorder (ASD) and in matched ...

    • Different Cortical Dynamics in Face and Body Perception: An MEG study 

      Meeren, Hanneke K. M.; de Gelder, Beatrice; Ahlfors, Seppo P.; Hämäläinen, Matti S.; Hadjikhani, Nouchine (Public Library of Science, 2013)
      Evidence from functional neuroimaging indicates that visual perception of human faces and bodies is carried out by distributed networks of face and body-sensitive areas in the occipito-temporal cortex. However, the dynamics ...

    • Diffusion Spectrum Imaging Shows the Structural Basis of Functional Cerebellar Circuits in the Human Cerebellum In Vivo 

      Granziera, Cristina; Schmahmann, Jeremy Dan; Hadjikhani, Nouchine; Meyer, Heiko; Meuli, Reto; Wedeen, Van Jay; Krueger, Gunnar (Public Library of Science, 2009)
      Background: The cerebellum is a complex structure that can be affected by several congenital and acquired diseases leading to alteration of its function and neuronal circuits. Identifying the structural bases of cerebellar ...

    • Early Category-Specific Cortical Activation Revealed by Visual Stimulus Inversion 

      Meeren, Hanneke K. M.; Hadjikhani, Nouchine; Ahlfors, Seppo P.; Hämäläinen, Matti S.; de Gelder, Beatrice M.L. (Public Library of Science, 2008)
      Visual categorization may already start within the first 100-ms after stimulus onset, in contrast with the long-held view that during this early stage all complex stimuli are processed equally and that category-specific ...

    • The Importance of Networking in Autism Gaze Analysis 

      Guillon, Quentin; Afzali, Mohammad H.; Rogé, Bernadette; Baduel, Sophie; Kruck, Jeanne; Hadjikhani, Nouchine (Public Library of Science, 2015)
      Visual scanning of faces in individuals with Autism Spectrum Disorder (ASD) has been intensively studied using eye-tracking technology. However, most of studies have relied on the same analytic approach based on the ...

    • Intact perception but abnormal orientation towards face-like objects in young children with ASD 

      Guillon, Quentin; Rogé, Bernadette; Afzali, Mohammad H.; Baduel, Sophie; Kruck, Jeanne; Hadjikhani, Nouchine (Nature Publishing Group, 2016)
      There is ample behavioral evidence of diminished orientation towards faces as well as the presence of face perception impairments in autism spectrum disorder (ASD), but the underlying mechanisms of these deficits are still ...

    • It’s All in the Eyes: Subcortical and Cortical Activation During Grotesqueness Perception in Autism 

      Zürcher, Nicole R.; Donnelly, Nick; Rogier, Ophélie; Russo, Britt; Hippolyte, Loyse; Hadwin, Julie; Lemonnier, Eric; Hadjikhani, Nouchine (Public Library of Science, 2013)
      Atypical face processing plays a key role in social interaction difficulties encountered by individuals with autism. In the current fMRI study, the Thatcher illusion was used to investigate several aspects of face processing ...

    • Migraine Aura: Retracting Particle-Like Waves in Weakly Susceptible Cortex 

      Dahlem, Markus A.; Hadjikhani, Nouchine (Public Library of Science, 2009)
      Cortical spreading depression (SD) has been suggested to underlie migraine aura. Despite a precise match in speed, the spatio-temporal patterns of SD observed in animal cortex and aura symptoms mapped to the cortical surface ...

    • The missing link: Enhanced functional connectivity between amygdala and visceroceptive cortex in migraine 

      Hadjikhani, Nouchine; Ward, Noreen; Boshyan, Jasmine; Napadow, Vitaly J.; Maeda, Yumi; Truini, Andrea; Caramia, Francesca; Tinelli, Emanuele; Mainero, Caterina (SAGE Publications, 2013)
      Background Migraine is a neurovascular disorder, in which altered functional connectivity between pain-modulating circuits and the limbic system may play a role. Cortical spreading depression (CSD), which underlies ...

    • Perception of Social Cues of Danger in Autism Spectrum Disorders 

      Zürcher, Nicole R.; Rogier, Ophélie; Boshyan, Jasmine; Hippolyte, Loyse; Russo, Britt; Gillberg, Nanna; Helles, Adam; Ruest, Torsten; Lemonnier, Eric; Gillberg, Christopher; Hadjikhani, Nouchine (Public Library of Science, 2013)
      Intuitive grasping of the meaning of subtle social cues is particularly affected in autism spectrum disorders (ASD). Despite their relevance in social communication, the effect of averted gaze in fearful faces in conveying ...

    • A Randomised Controlled Trial of Bumetanide in the Treatment of Autism in Children 

      Lemonnier, Éric; Degrez, Céline; Phelep, Morgane; Tyzio, Roman; Josse, Florent; Grandgeorge, Marine; Hadjikhani, Nouchine; Ben-Ari, Yehezkel (Nature Publishing Group, 2012)
