neurobics :keeping the brain alive

How do we excercise our brain it is a tough ask if we do not respond to the question how the brain survives.

The brain receives, organizes, and distributes information to guide our actions and also stores important information for future use. The problems we associate with getting older— forgetfulness, not feeling "sharp," or having difficulty learning
new things—involve the cerebral cortex and the hippocampus.
The cortex is the part of the brain that is responsible for our unique human abilities of memory, language, and abstract thought. The hippocampus coordinates incoming sensory information from the cortex and organizes it into memories. The
wiring of the cortex and hippocampus is designed to form links (or associations) between different sensory representations of the same object, event, or behavior.
Every cortical region sends and receives millions of impulses via these axons to and from dozens of other cortical regions. The brain contains literally hundreds
of miles of such wires. Thus, the cortex resembles an intricate web, VISUAL AREAS OF THE CORTEX with each region linked directly or indirectly to many other regions. Some of these connections are between areas that process similar information, such as the thirty involving vision, while other connections are between dissimilar
areas, such as touch and smell. The network of pathways between cortical regions that do many different things is what allows the cortex to be so adept at forming associations. Like the cortex, the hippocampus plays an important role in forming associations. The senses continually flood the brain with information, some of it vital but much of it unimportant. You don't need to remember the face of everyone you pass on the street, but you do want to recognize someone you just met at your boss's party! To prevent the information overload that would accompany having to remember too much, the hippocampus sifts through the barrage of incoming information
from the cortex and picks out what to store or discard. In other words, the hippocampus acts like a central clearinghouse, deciding what will be placed into long-term memory, and then, when called upon, retrieving it. The hippocampus's decision to store a memory is believed to hinge on two factors: whether the information has emotional significance, or whether it relates to something we already know.
Because each memory is represented in many different cortical areas, the stronger and richer the network of associations or representations you have built into your brain, the more your brain is protected from the loss of any one representation.These multisensory representations for tasks like remembering names were always available to you, but early on, your brain established an effective routine for meeting people that relied primarily on visual cues. An important part of the Neurobic strategy is to help you "see" in other ways—to use other
senses to increase the number and range of associations you make. The larger your "safety net," the better your chances of solving a problem or meeting a challenge because you simply have more pathways available to reach a conclusion.
The early process of neurobics emerged in the gurukools of vedic India.
The process was to alloy mans senses with nature and give him the ability to learn out of the infinite.
The chakravuha the vipassana meditation have all been explained like this as all repesent the matrix of the mind interconnection association and the rest.
So neurologics has its root node n the earliest vedic scripture.
