Cognitive Neuroimaging

The cognitive neuroimaging team provides support for all human research studies at MBI, which represents the largest body of users of the platform. The recent growth has allowed us to hire two new technical assistants. The team provides technical support for psychophysiological and ocular motor studies, functional and structural MRI, electroencephaolography (EEG), transcranial magnetic stimulation (TMS). We also perform continued research on topics such as combining MRI and TMS, and multiband fMRI recording.

In collaboration with the Victorian Biomedical Imaging Capability (VBIC), development of training protocols for non-radiographer research-only 3T MRI operators continued from 2013 and was completed in 2014. The first of the non-radiographer MRI operators successfully completed the training in 2014.

The common role of the intraparietal sulcus in mental rotation and antisaccades

A. Papadopoulos, G. Egan, J. Fielding, S. Jamadar

As the functional properties of the Intraparietal sulcus (IPS) are considered similar across human and non-human primates, non-human primate models have been used extensively to understand the role of the IPS in cognitive processes such as attention and working memory. However, despite the great advances in knowledge about the IPS structure and function from non-human primate studies, there remains difficulty in completely mapping the human IPS subregions to match that of non-human primates, as the human parietal cortex is greatly expanded in comparison to non-human primates.

Compensation-related utilisation of neural circuits hypothesis in cognitive control

Sharna Jamadar, Gary Egan

A decline in cognitive function is considered an inevitable consequence of the ageing process, even in healthy ageing adults. It is commonly believed that individuals can partly compensate for this decline by employing new strategies and/or additional brain regions to successfully perform cognitive tasks.
