On rotational invariance in adaptive spatial filtering of fMRI data

NeuroImage, 2006
Canonical correlation analysis (CCA) has previously been shown to work well for detecting neural activity in fMRI data. The reason is that CCA enables simultaneous temporal modeling and adaptive spatial filtering of the data. This article introduces a novel method for adaptive anisotropic filtering using the CCA framework and compares it to a ...

Cortical representations of numbers and nonsymbolic quantities expand and segregate in children from 5 to 8 years of age

PLoS Biology, 2023
Number symbols, such as Arabic numerals, are cultural inventions that have transformed human mathematical skills. Although their acquisition is at the core of early elementary education in children, it remains unknown how the neural representations of ...

The Left Amygdala and Right Frontoparietal Cortex Support Emotional Adaptation Aftereffects

Brain Sciences
Adaptation aftereffects—in which prolonged prior experience (adaptation) can bias the subsequent judgment of ambiguous stimuli—are a ubiquitous phenomenon.

S4-2: Hierarchy of Direction-Tuned Motion Adaptation in Human Visual Cortex

i-Perception, 2012
Prolonged exposure to a single direction of motion alters perception of subsequent static or dynamic stimuli and induces substantial changes in behaviors of motion-sensitive neurons, but it remains unclear about an origin of neural adaptation and neural ...

Joint contribution of adaptation and neuronal population recruitment to response level in visual area MT: a computational model

Scientific Reports
Adaptation is a form of short-term plasticity triggered by prolonged stimulus exposure, altering perceptual sensitivity to stimulus features through reduced neuronal firing rates.

Domain Adaptation-enhanced searchlight: enabling classification of brain states from visual perception to mental imagery

Brain Informatics
In cognitive neuroscience and brain-computer interface research, accurately predicting imagined stimuli is crucial. This study investigates the effectiveness of Domain Adaptation (DA) in enhancing imagery prediction using primarily visual data from fMRI ...
