How do we become aware of stimuli in our spatial environment?

Spatial attention is usually associated with dorsal parietal visual stream processing and damage to these
regions can result in an inability to detect contralesional presented stimuli. Yet the processing of stimuli
features themselves (e.g. details of faces or houses) happens in more ventral visual streams. Although a lot
is known about these dorsal and ventral visual stream processing pathways independently, almost nothing is
known on how they interact. In this project I will use a combination of techniques such as TMS, fMRI and DTI
to investigate how the dorsal stream influences the ventral stream. The results will lead to a better
understanding on how our brain creates awareness of the stimuli in our spatial environment.
