Learning Contextual Reward Expectations for Value Adaptation [PDF]
, 2018 Substantial evidence indicates that subjective value is adapted to the statistics of reward expected within a given temporal context. However, how these contextual expectations are learned is poorly understood.

Neural codes for one’s own position and direction in a real-world “vista” environment [PDF]
, 2018 Humans, like animals, rely on an accurate knowledge of one’s spatial position and facing direction to keep orientated in the surrounding space. Although previous neuroimaging studies demonstrated that scene-selective regions (the parahippocampal place ...

Analyzing fMRI experiments with structural adaptive smoothing procedures
NeuroImage, 2006 Data from functional magnetic resonance imaging (fMRI) consists of time series of brain images which are characterized by a high noise level and a low signal-to-noise ratio. We provide a complete procedure for fMRI analysis. In order to reduce noise and to improve signal detection the fMRI data is spatially smoothed.

Adaptation of a Haptic Robot in a 3T fMRI [PDF]
Journal of Visualized Experiments, 2011 Functional magnetic resonance imaging (fMRI) provides excellent functional brain imaging via the BOLD signal with advantages including non-ionizing radiation, millimeter spatial accuracy of anatomical and functional data, and nearly real-time analyses.

Bayesian symmetrical EEG/fMRI fusion with spatially adaptive priors [PDF]
NeuroImage, 2011 In this paper, we propose a novel symmetrical EEG/fMRI fusion method which combines EEG and fMRI by means of a common generative model. We use a total variation (TV) prior to model the spatial distribution of the cortical current responses and hemodynamic response functions, and utilize spatially adaptive temporal priors to model their temporal shapes.

Motion adaptation and attention: A critical review and meta-analysis [PDF]
, 2019 The motion aftereffect (MAE) provides a behavioural probe into the mechanisms underlying motion perception, and has been used to study the effects of attention on motion processing.

Adaptation in the rodent olfactory bulb measured by fMRI [PDF]
Magnetic Resonance in Medicine, 2005 AbstractEffective evaluation of the odor environment necessitates the ability to attenuate responses to potent background odors in favor of novel and less robust stimuli. Olfactory receptor neuron studies suggest that some of this adaptation takes place in the primary sensory neurons, but the more extensive adaptation seen in higher cortical areas ...

Temporal Contiguity Training Influences Behavioral and Neural Measures of Viewpoint Tolerance
Frontiers in Human Neuroscience, 2018 Humans can often recognize faces across viewpoints despite the large changes in low-level image properties a shift in viewpoint introduces. We present a behavioral and an fMRI adaptation experiment to investigate whether this viewpoint tolerance is ...
