Temporal excitation patterns on the cerebral cortex as a result of migraine modeling

Kroos, J.M.; Diez, I.; Cortes, J.M.; Stramaglia, S.

; Gerardo-Giorda, L. (2016-06-29)

The complex, highly individual, geometry of the cerebral cortex in humans presents a major challenge in studying the spreading of spontaneous neuronal activity. Recent computational advances [1] allow to simulate the ...

Patient-specific computational modeling of Cortical Spreading Depression via Diffusion Tensor Imaging

Kroos, J.M.; Marinelli, I.; Diez, I.; Cortes, J.M.; Stramaglia, S.

; Gerardo-Giorda, L. (2016-06-29)

Cortical Spreading Depression (CSD), a depolarization wave originat- ing in the visual cortex and traveling towards the frontal lobe, is com- monly accepted as a correlate of migraine visual aura. As of today, little is ...

Information Flow between Resting-State Networks

Diez, I.; Erramuzpe, A.; Escudero, I.; Mateos, B.; Cabrera, A.; Marinazzo, D.; Sanz-Arigita, E.J.; Stramaglia, S.

; Cortes Diaz, J.M. (2015-12-31)

The resting brain dynamics self-organize into a finite number of correlated patterns known as resting-state networks (RSNs). It is well known that techniques such as independent component analysis can separate the brain ...

Extreme brain events: Higher-order statistics of brain resting activity and its relation with structural connectivity

Amor, T.A.; Russo, R.; Diez, I.; Bharath, P.; Zirovich, M.; Stramaglia, S.

; Cortes, J.M.; de Arcangelis, L.; Chialvo, D.R. (2015-12-31)

The brain exhibits a wide variety of spatiotemporal patterns of neuronal activity recorded using functional magnetic resonance imaging as the so-called blood-oxygenated-level-dependent (BOLD) signal. An active area of work ...

Geometry shapes propagation: Assessing the presence and absence of cortical symmetries through a computational model of cortical spreading depression

Kroos, J.M.; Diez, I.; Cortes, J.M.; Stramaglia, S.

; Gerardo-Giorda, L. (2015-12-31)

Cortical spreading depression (CSD), a depolarization wave which originates in the visual cortex and travels toward the frontal lobe, has been suggested to be one neural correlate of aura migraine. To the date, little is ...

Lagged and instantaneous dynamical influences related to brain structural connectivity

Alonso, C.; Diez, I.; Remaki, L.; Escudero, I.; Mateos, B.; Rosseel, Y.; Marinazzo, D.; Stramaglia, S.

; Cortes, J.M. (2015-12-31)

Contemporary neuroimaging methods can shed light on the basis of human neural and cognitive specializations, with important implications for neuroscience and medicine. Indeed, different MRI acquisitions provide different ...
