Neuroscience The range of disciplines that make up the neurosciences is growing. What was first the study of brain and nerve tissues has steadily widened to include brain anatomy, structure, and chemistry, hemispheric studies of the left and right cortex, artificial intelligence,brain development, perception, the senses, learning, memory, cognition, brain disorders, consciousness, etc. The proliferation of disciplines clustering about the brain is testimony to the interconnection of the scientific concerns in the same way the brain is an interconnection of tissue and structures. Ask a question like: "Why can't I remember being born," and each of these sub disciplines are invoked. Each provides avenues of understanding the others will not completely touch. The complete answer (if there can be one) will be provided from them all. Like a jigsaw puzzle, each discipline provides new pieces to the picture of human nature.
