Neuroanatomy of reasoning processes

Right Parietal Cortex
Inferring information from given assertions is at the core of human reasoning ability. Involved cognitive processes include the understanding and integration of information into a mental model and drawing conclusions. We we are also interested in the identi cation of the role of associated brain regions.
To understand the neuroanatomy behind reasoing processes we analysed severaly imaging studies in a meta-analysis, and we also used functional magnetic resonance imaging and magnetic stimulation.

 Functional Brain Imaging

Transcranial Magnetic Stimulation
The aim of our transcranial magnetic stimulation (TMS) studies was to use this method to explore the role of the  parietal lobe in deductive reasoning. With this method we established a causal connection of the SPL in deductive reasoning.
