Conclusions and a New Brain Metaphor
Conclusions and a New Brain Metaphor
This chapter discusses the inability of brain imaging techniques such as functional magnetic resonance imaging (fMRI) to search for brain correlates of cognitive activity. Empirical observations reveal inconsistencies in the cognitive neuroscience research papers along with inconsistencies in the brain imaging meta-studies. A high degree of variability is also exhibited by traditional experimental brain lesioning and stimulation techniques. The chapter discusses problems with cognitive neuroscientific research, including a poor definition of cognitive processes, lack of empirical results backing the research, and imaging experiments conducted on macroscopic levels by investigators rather than on microscopic levels. General principles on which macroscopic organization of the brain is based, including distribution of activated areas in brain, interconnections among brain regions, and polyfunctionality of the brain, are presented.
