In-vivo magnetic resonance imaging of the structural core of the Papez circuit in humans

Reto Meuli, Cristina Granziera, Nouchine Hadjikhani

Papez circuit is one of the major pathways of the limbic system, and it is involved in the control of memory and emotion. Structural and functional alterations have been reported in psychiatric, neurodegenerative, and epileptic diseases. Despite the clinic ...

Hedging Your Bets by Learning Reward Correlations in the Human Brain

Human subjects are proficient at tracking the mean and variance of rewards and updating these via prediction errors. Here, we addressed whether humans can also learn about higher-order relationships between distinct environmental outcomes, a defining ecolo ...

Separate encoding of model-based and model-free valuations in the human brain

Behavioral studies have long shown that humans solve problems in two ways, one intuitive and fast (System 1, model-free), and the other reflective and slow (System 2, model-based). The neurobiological basis of dual process problem solving remains unknown d ...

Impact of transient emotions on functional connectivity during subsequent resting state: A wavelet correlation approach

Dimitri Nestor Alice Van De Ville

The functional properties of resting brain activity are poorly understood, but have generally been related to self-monitoring and introspective processes. Here we investigated how emotionally positive and negative information differentially influenced subs ...

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 ...

EARLY-ONSET DYSFUNCTION OF RETROSPLENIAL CORTEX PRECEDES OVERT AMYLOID PLAQUE FORMATION IN Tg2576 MICE

Guillaume Poirier

A mouse model of amyloid pathology was used to first examine using a cross sectional design changes in retrosplenial cortex activity in transgenic mice aged 5, 11, 17, and 23 months. Attention focused on: (1) overt amyloid labeled with beta-amyloid((1-42)) ...

Psychogenic amnesia and self-identity: a multimodal functional investigation

Olaf Blanke

Background: Patients with psychogenic amnesia generally suffer from episodic memory deficits associated with an impairment of self-identity. While the first is generally attributed to limbic dysfunction, the latter might be related to posterior parietal co ...

The thalamocortical vestibular system in animals and humans

Olaf Blanke, Christophe Lopez

The vestibular system provides the brain with sensory signals about three-dimensional head rotations and translations. These signals are important for postural and oculomotor control, as well as for spatial and bodily perception and cognition, and they are ...

Human Primary Auditory Cortex Follows the Shape of Heschl's Gyrus

Melissa Saenz, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, Stephanie Clarke

The primary auditory cortex (PAC) is central to human auditory abilities, yet its location in the brain remains unclear. We measured the two largest tonotopic subfields of PAC (hA1 and hR) using high-resolution functional MRI at 7 T relative to the underly ...

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 ...
