The ‘Epilogue’ asks: Will we ever truly understand the brain? Modern imaging techniques, such as fMRI, have provided valuable insights into the localization of specific mental actions in the brain. However, fMRI is an indirect method, measuring bloodflow instead of actual neuronal activity. Blood flow from surrounding areas may cloud the area being investigated, and some processes may not increase blood flow at all. Even if we do eventually know where things happen, it will not tell us how they have occurred. Thus, it is likely that our brains will continue to confound our brains for many more years to come.
