Age-Related Changes in BOLD Activation Pattern in Phonemic Fluency Paradigm: An Investigation of Activation, Functional Connectivity and Psychophysiological Interactions.

Frontiers in aging neuroscience

La C, Garcia-Ramos C, Nair VA, Meier TB, Farrar-Edwards D, Birn R, Meyerand ME, Prabhakaran V.
PMID: 27242519
Front Aging Neurosci. 2016 May 23;8:110. doi: 10.3389/fnagi.2016.00110. eCollection 2016.

Healthy aging is associated with decline of cognitive functions. However, even before those declines become noticeable, the neural architecture underlying those mechanisms has undergone considerable restructuring and reorganization. During performance of a cognitive task, not only have the task-relevant...

Front Hum Neurosci. 2012 Oct 11;6:281. doi: 10.3389/fnhum.2012.00281. eCollection 2012.

Parallel Independent Component Analysis (para-ICA) is a multivariate method that can identify complex relationships between different data modalities by simultaneously performing Independent Component Analysis on each data set while finding mutual information between the two data sets. We use...

Characterizing the relationship between lesion-activation distance using fMRI and verbal measures in brain tumor patients.

Interdisciplinary neurosurgery : Advanced techniques and case management

Riley SP, Chu DY, Nair VA, Baskaya MK, Kuo JS, Meyerand ME, Prabhakaran V.
PMID: 34950570
Interdiscip Neurosurg. 2022 Mar;27. doi: 10.1016/j.inat.2021.101391. Epub 2021 Sep 29.

Functional resonance magnetic imaging (fMRI) allows for identification of eloquent cortex in pre-treatment planning. Previous studies have shown a correlation among lesion to activation distance (LAD) measures and morbidity and mortality. This study investigates the relationship between LAD, well-established...
