Functional near infrared spectroscopy (fNIRS) to assess cognitive function in infants in rural Africa [PDF]

open access: yes, 2011
Cortical mapping of cognitive function during infancy is poorly understood in low-income countries due to the lack of transportable neuroimaging methods. We have successfully piloted functional near infrared spectroscopy (fNIRS) as a neuroimaging tool in

Robust Image Classification Using a Low-Pass Activation Function and DCT Augmentation

open access: yesIEEE Access, 2021
Convolutional Neural Network’s (CNN’s) performance disparity on clean and corrupted datasets has recently come under scrutiny. In this work, we analyse common corruptions in the frequency domain, i.e., High Frequency corruptions (HFc, e.g.,

Implicit cognition is impaired and dissociable in a head-injured group with executive deficits [PDF]

open access: yes, 2005
Implicit or non-conscious cognition is traditionally assumed to be robust to pathology but Gomez-Beldarrain et al (1999, 2002) recently showed deficits on a single implicit task after head injury.
