Neural processing of facial identity and expression in adults with and without autism: A multi-method approach

NeuroImage: Clinical, 2021
The ability to recognize faces and facial expressions is a common human talent. It has, however, been suggested to be impaired in individuals with autism spectrum disorder (ASD). The goal of this study was to compare the processing of facial identity and

Orientation sensitivity to graspable objects: An fMRI adaptation study

NeuroImage, 2007
It has been proposed that vision-for-perception and vision-for-action are subserved by distinct streams of visual processing, the ventral and dorsal stream, respectively [Milner, A. D., Goodale, M. A., 1995. The visual brain in action. Oxford University Press, Oxford]. Such a distinction has been supported by a recent functional magnetic resonance (fMR)

Shorter cortical adaptation in dyslexia is broadly distributed in the superior temporal lobe and includes the primary auditory cortex

eLife, 2018
Studies of the performance of individuals with dyslexia in perceptual tasks suggest that their implicit inference of sound statistics is impaired.

Do infants represent the face in a viewpoint-invariant manner? Neural adaptation study as measured by near-infrared spectroscopy

Frontiers in Human Neuroscience, 2011
Recent adult fMRI studies reported that face sensitive cortical areas showed attenuated responses to the repeated presentation of an identical facial image compared to the presentation of different facial images (fMRI-adaptation effects: e.g., Andrews ...

Optimizing preprocessing and analysis pipelines for single-subject fMRI: 2. Interactions with ICA, PCA, task contrast and inter-subject heterogeneity. [PDF]

PLoS ONE, 2012
A variety of preprocessing techniques are available to correct subject-dependant artifacts in fMRI, caused by head motion and physiological noise. Although it has been established that the chosen preprocessing steps (or "pipeline") may significantly ...

Olfactory fMRI Activation Pattern Across Different Concentrations Changes in Alzheimer’s Disease

Frontiers in Neuroscience, 2019
The olfactory involvement is an early feature of Alzheimer’s disease (AD). Olfactory functional MRI (fMRI) is an objective method to evaluate the olfactory function, but might be affected by the individual variation and the magnetic susceptibility ...

FMRI evidence of 'mirror' responses to geometric shapes. [PDF]

PLoS ONE, 2012
Mirror neurons may be a genetic adaptation for social interaction. Alternatively, the associative hypothesis proposes that the development of mirror neurons is driven by sensorimotor learning, and that, given suitable experience, mirror neurons will ...

Quantitative modeling of the emergence of macroscopic grid-like representations

eLife
When subjects navigate through spatial environments, grid cells exhibit firing fields that are arranged in a triangular grid pattern. Direct recordings of grid cells from the human brain are rare.

Neuroanatomic correlates of the feature-salience hierarchy in face processing: an fMRI -adaptation study.

Neuropsychologia, 2012
Previous fMRI studies suggest that faces are represented holistically in human face processing regions. On the other hand, behavioral studies have also shown that some facial features are more salient than others for face recognition: the neural basis of

Adaptive Entropy Rates for fMRI Time-Series Analysis [PDF]

, 2001
In previous work [Tsai et al, 1999] we introduced an information theoretic approach for analysis of fMRI time-series data. Subsequently, [Kim et al, 2000] we established a relationship between our information theoretic approach and a simple non-parametric hypothesis test.
