Localization of the primary gustatory cortex within insular lobe using structural white matter connectivity evidence as determined by diffusion tensor imaging

INTRODUCTION: The primary taste cortex localisation has been inconsistent in previous research. The current study aims to divide the insular lobe into subdivisions to determine investigate their individual structural connectivity to taste processing areas of the brain. MATERIALS AND METHODS: Dif...
