The Brain and Cognitive Functions Centuries of philosophy and science have been dedicated to unraveling the mystery behind how cognition occurs‚ how it maps to areas of the brain‚ and to what degree cognition is dependant upon these various areas in which cognitive activities are located. Modern neuroscience has helped tremendously to provide some answers as have tests on brain trama patients such as Phineas Gage which revealed startling changes in individual behavior that can be linked to damage

Brain Based Learning For many years science and education have concentrated on learning and the mind‚ but today’s neuroscientists and educators are seeing learning from a different scope – the brain. From this viewpoint‚ learning is creating links – by linking the information in which the student has prior knowledge or interest‚ the student is able to expand upon this and learn something else which he can relate it to.

The brain has a specialized vasculature that extends from the surface to deep within the brain tissue‚ reaching all regions in order to meet the brain’s high metabolic demands. Exposures to toxic compounds entering the blood have the potential to access this vasculature leaving the brain susceptible to possible neurotoxicity. Currently‚ there are over 200 known chemicals that have been correlated with neurotoxicity. A protective mechanism called the blood brain barrier (BBB) was first discovered
