Impaired Imagery for Upper Limbs

The brain processes associated with mental imagery have long been a matter of debate. Neuroimaging and neuropsychological studies have yielded diverging evidence of mental transformation activating the right hemisphere, the left hemisphere, or both. Here, ...

Modeling the neural correlates of imitation from a neuropsychological perspective

Biljana Petreska von Ritter-Zahony

Imitation is a fundamental mechanism by which humans learn and understand the actions of others. This thesis addresses the low-level neural mechanisms underlying the imitation of meaningless gestures, using tools from computational neuroscience. We investi ...

Spatial heterogeneity of functional Magnetic Resonance Imaging indices of dorsolateral prefrontal cortex activation evoked by a working memory task: A comparison of patients with schizophrenia and healthy controls

Background: This study is based on the hypothesis that functional Magnetic Resonance Imaging (fMRI) indices in the dorsolateral prefrontal cortex (DLPFC) of schizophrenia patients are spatially more heterogeneous than healthy controls for activation evoked ...

Predicting Human Resting-State Functional Connectivity from structural Connectivity

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet, Olaf Sporns

In the cerebral cortex, the activity levels of neuronal populations are continuously fluctuating. When neuronal activity, as measured using functional MRI (fMRI), is temporally coherent across 2 populations, those populations are said to be functionally co ...

Enhanced long-term microcircuit plasticity in the valproic Acid animal model of autism

Henry Markram, Kamila Markram, Tania Rinaldi, Jean-Vincent Le Bé, Imad Riachi, Guilherme Silva

A single intra-peritoneal injection of valproic acid (VPA) on embryonic day (ED) 11.5 to pregnant rats has been shown to produce severe autistic-like symptoms in the offspring. Previous studies showed that the microcircuitry is hyperreactive due to hyperco ...

Evolution amplified processing with temporally dispersed slow neuronal connectivity in primates

Hassan Ghaziri, Giorgio Innocenti

The corpus callosum (CC) provides the main route of communication between the 2 hemispheres of the brain. In monkeys, chimpanzees, and humans, callosal axons of distinct size interconnect functionally different cortical areas. Thinner axons in the genu and ...

Seeing the phantom: a functional magnetic resonance imaging study of a supernumerary phantom limb

Olaf Blanke, Sebastian Dieguez Falcon, François Lazeyras

OBJECTIVE: Supernumerary phantom limb (SPL) is a rare neurological manifestation where patients with a severe stroke-induced sensorimotor deficit experience the illusory presence of an extra limb that duplicates a real one. The illusion is most often exper ...

When motion takes form

Manuel Mercier

When and where is visual motion processed in the human brain? This question is highly relevant considering the importance of motion for our perception of the dynamical world surrounding us. In the present work we studied motion processing, firstly through ...

Modeling the effects of midazolam on cortical and thalamic neurons

Sean Lewis Hill

Controversy exists regarding the site where anesthetics act in the brain to produce sedation and unconsciousness. Actions in the cerebral cortex and thalamus are likely, although the relative importance of each site is unclear. We used in computo modeling ...

Investigation of high-resolution functional magnetic resonance imaging by means of surface and array radiofrequency coils at 7 T

Rolf Gruetter, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques

In this investigation, high-resolution, 1x1x1-mm(3) functional magnetic resonance imaging (fMRI) at 7 T is performed using a multichannel array head coil and a surface coil approach. Scan geometry was optimized for each coil separately to exploit the stren ...
