Abstract

Cognitive scientists use current knowledge of neuroanatomy, neuroscanning, neurochemistry, and electrophysiology to develop testable scientific theories explaining brain-based cognitive processes. Neuroscientists tend to emphasize what is known about brain functioning and de-emphasize the huge amount of central nervous system (CNS) functional operation that is not understood. Neurotransmission theory explains the neural connections and brain structure required for brain-based cognitive functions such as motor activity, perception, communication, and calculation. Classic neuroanatomy based on sequential transmission theory has proved to be less successful in demonstrating brain-based correlates for thought, particularly associative thought. Mind-based processes are considerably important to neuroscientists. These processes are beyond the capacity of artificial intelligence systems. Without these processes human beings could be modeled as biological systems operating as automatons. These are the “higher” level functions utilized by the conscious individual to maintain functional capacity in a derivative perceptual representation of the external world. These are the systems that integrate and associate disparate biological brain systems into the complex phenomenon called consciousness. Parallel neuro-processing theories suggest that the CNS might function in a nonsequential manner.
