## Neural underpinnings of planning different interactions with tools: a functional magnetic resonance imaging study

### Bartosz Michałowski

#### Abstract

The aim of this thesis was to investigate the contribution of the praxis representation network (PRN) – a set of left-hemispheric parietal, frontal, and temporal areas implicated in the control of skilled, purposeful manual actions – to the preparation of actions directed at familiar tools and motivated by disparate, both functional and non-functional goals. A series of two functional magnetic resonance imaging experiments was administered to 20 strongly right-handed participants. Their task was to plan and subsequently pantomime the execution of grasping/reaching towards tools with different intentions in mind. The results showed that the key nodes of PRN were more involved in planning grasping actions that did not involve tool use. This was the case irrespective of the hand used for task performance. These findings indicate that modulations of activity within the ventro-dorsal divisions of PRN are sensitive to more cognitively demanding aspects of task performance. Consequently, this thesis contributes to the field of cognitive neuroscience of action and shed a new light on how disparate intended action outcomes combined with task constraints influence the perception of object affordances, and to what extent they modulate the fMRI activity within the parieto-frontal action networks and beyond them.
