Temporal Dynamics of Functional Connectivity after TES​
Cambridge, MA - Battelli lab, IIT@Harvard

 

Exploring changes in functional connectivity of dorsal and ventral attention network after transcranial electrical stimulation (TES) and TMS to parietal cortex. We systematically investigate the temporal profile of functional connectivity modulation and behavioral impact using brain stimulation.

 

Techniques: TMS, tRNS, fMRI, EEG, eye-tracking.

Predictive Position Perception
Toulouse, France​ - Cavanagh & VanRullen Labs

 

We examined the role of the dorsal attention network had in predicting the position of objects in our visual field after eye-movements and during motion.

Techniques: TMS, EEG, eye-tracking.

Predictive feedback to V1 during saccades
Glasgow, Scotland - Muckli lab
During my PhD I focused on the integration of predictive feedback signals with sensory input in V1 across eye-movements.
 
Techniques: psychophysics, fMRI & eye-tracking
