A 7 tesla FMRI study of amygdala responses to fearful faces

Wietske Van der Zwaag, Nouchine Hadjikhani, Nicole Regula Zürcher Wimmer

The amygdalae are involved in the perception of emotions such as happiness, anger and fear. Because of their proximity to the sinuses, the image signal intensity in T2* weighted fMRI data is often affected by signal loss due to through-slice dephasing, esp ...

Activelets: Wavelets for sparse representation of hemodynamic responses

Michaël Unser, Dimitri Nestor Alice Van De Ville, Ildar Khalidov, François Lazeyras

We propose a new framework to extract the activity-related component in the BOLD functional magnetic resonance imaging (fMRI) signal. As opposed to traditional fMRI signal analysis techniques, we do not impose any prior knowledge of the event timing. Inste ...

Functional MRI connectivity as a predictor of the surgical outcome of epilepsy

Roberto Martuzzi

Purpose: In planning epilepsy surgery, it is important to be able to assess the likelihood of success of surgery for each patient so that the possible risk and benefit can be properly considered. In this study, functional connectivity was investigated as ...

Decoding brain states from fMRI connectivity graphs

Dimitri Nestor Alice Van De Ville, Jonas Richiardi

Functional connectivity analysis of fMRI data can reveal synchronised activity between anatomically distinct brain regions. Here, we extract the characteristic connectivity signatures of different brain states to perform classification, allowing us to deco ...

Neural Mechanisms of the Embodied Self

Ravi Tej Sai Giridhar Tadi

What is it like to have a body? The unitary experience of the self and the body accompanied by unambiguous self-location and egocentric visuo-spatial perspective are essential aspects of the embodied self. They play a vital role for dynamic whole body huma ...

Alpha band oscillations correlate with illusory self-location induced by virtual reality

Olaf Blanke, Bigna Lenggenhager, Pär Halje

Neuroscience of the self has focused on high-level mechanisms related to language, memory or imagery of the self. However, recent evidence suggests that low-level mechanisms such as multisensory and sensorimotor integration may play a fundamental role in s ...

The impact of disappointment in decision making: inter-individual differences and electrical neuroimaging

Disappointment, the emotion experienced when faced to reward prediction errors (RPEs), considerably impacts decision making (DM). Individuals tend to modify their behavior in an often unpredictable way just to avoid experiencing negative emotions. Despite ...

Global Functional Connectivity Deficits in Schizophrenia Depend on Behavioral State

Roy Salomon

Schizophrenia is a devastating psychiatric illness characterized by deterioration of cognitive and emotional processing. It has been hypothesized that aberrant cortical connectivity is implicated in the disease (Friston, 1998), yet previous studies of func ...

Sparse Source Recovery from Boundary Measurements using an Extension of Prony's Method for the Poisson Equation

Djano Kandaswamy

Electroencephalography (EEG) is a key modality to monitor brain activity with high temporal resolution. EEG makes use of an array of electrodes to measure the electrical potential on the scalp. While most traditional EEG analyses have looked at EEG rhythms ...

Single Molecule Sensing

Claudio Dellagiacoma

Living organisms consist of cells, the elementary components of which are proteins providing cellular structures and functionality. Nowadays, proteins of the size of one to a few tens of nanometers can be efficiently monitored by fluorescence microscopy an ...
