Combining multivariate voxel selection and support vector machines for mapping and classification of fMRI spatial patterns
In functional brain mapping, pattern recognition methods allow detecting multivoxel patterns
of brain activation which are informative with respect to a subject's perceptual or cognitive …

[HTML][HTML] Intermediate acoustic-to-semantic representations link behavioral and neural responses to natural sounds
Recognizing sounds implicates the cerebral transformation of input waveforms into semantic
representations. Although past research identified the superior temporal gyrus (STG) as a …

[HTML][HTML] The default mode network and the working memory network are not anti-correlated during all phases of a working memory task
Introduction The default mode network and the working memory network are known to be
anti-correlated during sustained cognitive processing, in a load-dependent manner. We …

Auditory cortex encodes the perceptual interpretation of ambiguous sound
The confounding of physical stimulus characteristics and perceptual interpretations of stimuli
poses a problem for most neuroscientific studies of perception. In the auditory domain, this …

Fast Gaussian Naïve Bayes for searchlight classification analysis
M Ontivero-Ortega, A Lage-Castellanos, G Valente… - Neuroimage, 2017 - Elsevier
The searchlight technique is a variant of multivariate pattern analysis (MVPA) that examines
neural activity across large sets of small regions, exhaustively covering the whole brain. This …

Task-dependent decoding of speaker and vowel identity from auditory cortical response patterns
Selective attention to relevant sound properties is essential for everyday listening situations.
It enables the formation of different perceptual representations of the same acoustic input …

Brain-based translation: fMRI decoding of spoken words in bilinguals reveals language-independent semantic representations in anterior temporal lobe
Bilinguals derive the same semantic concepts from equivalent, but acoustically different,
words in their first and second languages. The neural mechanisms underlying the …

The effect of spatial resolution on decoding accuracy in fMRI multivariate pattern analysis
Multivariate pattern analysis (MVPA) in fMRI has been used to extract information from
distributed cortical activation patterns, which may go undetected in conventional univariate …

Reconstructing the spectrotemporal modulations of real-life sounds from fMRI response patterns
Ethological views of brain functioning suggest that sound representations and computations
in the auditory neural system are optimized finely to process and discriminate behaviorally …
