altBrain scans have greatly expanded an understanding of the functions that are housed within the cerebrum. To quote Rita Carter, editor of Mapping the Mind:

Almost every mental function you can think of is fully or partly lateralized.

In other words, the cerebral hemispheres are hard-wired for very specific skills that, under normal circumstances, usually develop in one hemisphere or division. While it is true that certain areas are specialized for specific purposes, the brain can only be understood as one highly complex and integrated functional unit.

Dr. Restak, author of Mysteries of the Mind, wrote:

The great majority of its neuronal connections involve cross talk among neurons rather than the transfer of information to and from the rest of the body.

Evidence for lateralization can sometimes be observed in a brain scan (e.g., shows the side of the brain that is in charge of the particular function or task), although functions/systems can overlap or be involved in the same process, such as the memory system and the emotional system. A region in the hemisphere that is in charge of a specific task glows more brightly when compared to the matching region in the opposite hemisphere. Testing modalities have identified areas of the cerebrum that control or primarily direct specific functions (e.g., Broca’s Area for uttering audible speech, Wernicke’s Area for decoding audible speech).

Following is a summary of key functional contributions of each cerebral division.

The Two Frontal Cerebral Divisions

  • To set and achieve goals
  • To make and objective and timely decisions

 

  • To anticipate and make changes
  • To visualize, innovate, and meditate
altMaintaining Division

altHarmonizing Division

  • To supply services (dependably) needed for maintaining life
  • To run routines and habits

 

  • To build trust, connection, and peaceful foundations

Specific Skills Correlated by Cerebral Division

Basic cerebral functions are important as they permit human beings to learn skills and develop competencies that are critical to life on this planet as we know it. Following are examples of ways in which the cerebral functions  enable individuals to develop specific skills.
 

altPrioritizing

Division

altEnvisioning

Division

 

The Prioritizing Division  contains functions to assist you in developing skills related to: 

  • Inductive/deductive reasoning (logic, the researched view)
  • The ability to set goals, make decisions, prioritize the actions necessary to achieve goals, analyze everything for functionality (bounded shapes as well as abstract ideas)
  • Data-driven problem-solving (comparing, analyzing, summarizing)

The Envisioning Division  contains functions to assist you in developing skills related to: 

  • Active three-dimensional internal mental picturing
  • The ability to take in huge amounts of data (balcony view) second for second, notice when things are changing, identify trends, and compute context
  • Intuitive, innovative problem-solving (e.g., brainstorming new ideas, processes, products; meditating)

Unique Challenges

altPrioritizing

Division

altEnvisioning

Division

 

Prioritizers may be viewed by those with a different brain bent as insensitive, a people user, and a workaholic; may have limited access to the harmonizing division and can blow up easilywhen frustrated or crossed (e.g., Mt. Vesuvius). Tasks or activities that require use of the other three divisions (especially the diagonal Harmonizing 
division) are much more energy-exhaustive, such as:

  • Helping others to get along with each other and/or feel comfortable
  • Learning to speak foreign languages
  • Dressing (selecting colors, styles)
  • Direct spiritual experiences
  • Learning complicated dance routines

Envisioners may be viewed by those with a different brain bent as unpredictable, unrealistic, and undependable (due to penchant for spontaneity); dislikes details and routines and can quickly become bored with them. Tasks or activities that require use of the other three divisions (especially the diagonal Maintaining division) are much more energy-exhaustive, such as:

  • Routine self care (e.g., brushing teeth, washing face, applying makeup, styling own hair)
  • Detailed and repetitive routine procedures
  • Sequenced details (spelling)
  • Accuracy in addition (balancing check book)
  • Following rules and regulations precisely

The Two Posterior Cerebral Divisions

altMaintaining

Division

altHarmonizing 

Division

The Maintaining division
contains functions to assist you in developing skills related to: 

  • The ability to sequence a set of actions into a routine (a set of pre-made decisions) and follow it accurately
  • The tendency to more easily absorb information that is perceived as linear (e.g., rectangles, squares, lines, angles)

Occipital lobe (vision): sees and identifies details

Temporal lobe (auditory): listens for nouns and verbs (labels/directions)

Parietal lobe (kinesthetic): grasps and manipulates bounded shapes, tends to line up objects precisely

 

The Harmonizing division
contains functions to assist you in developing skills related to: 

  • The ability to compare everything to assess for the presence or absence of harmony
  • The tendency to more easily absorb information that is perceived as harmonically related (e.g., color, smiles, body language, oval or circular or rounded shapes)

Occipital lobe (vision): sees colors and reads nonverbals

Temporal lobe (auditory): listens for nonspeech sounds and the music of speech

Parietal lobe (kinesthetic): assesses touch connection and relational position of bounded shapes in the environment

  • Dealing with interruptions

Harmonizers may be viewed by those with a different brain bent as overly sensitive and overconforming or overcomplying in their effort to maintain harmony.

Tasks that require use of the other three divisions (especially the diagonal Prioritizing division) are much more energy-exhaustive, such as:

  • Making logical decisions
  • Completing cost-benefit analysis (e.g., financial)
  • Negotiating
  • Saying “no” or making unpopular decisions
