Detection of self-paced reaching movement intention from EEG signals

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Eileen Lew Yi Lee

Future neuroprosthetic devices, in particular upper limb, will require decoding and executing not only the user's intended movement type, but also when the user intends to execute the movement. This work investigates the potential use of brain signals reco ...

Cortical Current Density vs. Surface EEG for Event-Related Potential-based Brain-Computer Interface

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Mohit Kumar Goel

In this paper we use the cortical current density based inverse solution to classify Event Related Potential, in particular for error-related potential elicited during Brain-Computer Interface experiment. We selected discriminant cortical sources for compa ...

Altered branching patterns of Purkinje cells in mouse model for cortical development disorder

Giorgio Margaritondo

Disrupted cortical cytoarchitecture in cerebellum is a typical pathology in reeler. Particularly interesting are structural problems at the cellular level: dendritic morphology has important functional implication in signal processing. Here we describe a c ...

Delayed cortical impairment following lipopolysaccharide exposure in preterm fetal sheep

Yohan Van de Looij, François Lazeyras

Preterm infants exhibit chronic deficits in white matter (WM) and cortical maturation. Although fetal infection/inflammation may contribute to WM pathology, the factors contributing to cortical changes are largely unknown. We examined the effect of fetal l ...

Longitudinal MR Assessment of Hypoxic Ischemic Injury in the Immature Rat Brain

Rolf Gruetter, Yohan Van de Looij

Extremely preterm infants commonly show brain injury with long-term structural and functional consequences. Three-day-old (P3) rat pups share some similarities in terms of cerebral development with the very preterm infant (born at 24-28 weeks of gestation) ...

Diminished activity-dependent brain-derived neurotrophic factor expression underlies cortical neuron microcircuit hypoconnectivity resulting from exposure to mutant huntingtin fragments

Henry Markram, Michele Giugliano, Elena Katsyuba, Ozgün Gökce, Heike Runne, Luca Gambazzi

Although previous studies of Huntington's disease (HD) have addressed many potential mechanisms of striatal neuron dysfunction and death, it is also known, based on clinical findings, that cortical function is dramatically disrupted in HD. With respect to ...

Characterization of a mice model of human epilepsy with Multi-Electrode Arrays

Diego Ghezzi

We applied microelectrode array (MEA) recordings to study the generation and propagation of epileptform activity in various connected regions of cortico-hippocampal slices obtained from SynapsinI/II/III knockout (TKO) mice and the effects of the synaptic v ...

Whole-brain structural connectivity in patients with focal epilepsy studied with MRI diffusion spectrum imaging (DSI)

Jean-Philippe Thiran, Tobias Kober, Reto Meuli, Leila Cammoun, Alia Lemkaddem, François Lazeyras, Christoph Michel

In patients with focal epilepsy, diffusion MRI often reveals structural changes extending beyond visible lesions or show structural abnormalities even when the clinical scans are normal. MR Tractography based on diffusion tensor imaging allows non-invasive ...

Risk and risk prediction error signals in anterior insula

Most accounts of the function of anterior insula in the human brain refer to concepts that are difficult to formalize, such as feelings and awareness. The discovery of signals that reflect risk assessment and risk learning, however, opens the door to forma ...

Orientation specificity of learning vernier discriminations

Michael Herzog

Orientation selective neurons in the primary visual cortex typically respond to a range of orientations that covers 20, or more, while in psychophysical experiments, orientation bandwidth is often clearly narrower. Here, we measure the orientation specific ...
