Father & Son Analogy for the Human Brain

A simple way to understand how brain hemispheres work as a team to reach common goals is through "father and son" analogy for the human brain, in which a father is guiding his son, who is driving a car, to reach a destination.

The son is good at thinking logically and executing efficiently, as he is young and physically fit. He avoids other cars, people crossing roads, etc. and follows diversions, traffic lights, etc. on his own, but consults his old father, who is not as physically capable and strong with thorough logical processing capabilities but possesses wisdom derived from decades of experience of city roads (for traffic trends, dangers, shortcuts, etc.), about which path to take in order to reach the destination.

The way the son avoids other cars, people crossing roads, etc. and follows traffic lights, diversions, etc. on his own, the (interaction processing areas of) left hemisphere, i.e. LB, executes such repetitive and preset tasks on its own, which depicts unconscious processing in the brain.

The way the son consults his father for navigation, the left hemisphere consults (interaction processing areas of) the right hemisphere, i.e. VP, when judgement is to be made on how to interact further using past data from its hierarchical database, which depicts conscious processing in the brain.

Decision Making and Execution of an Interaction in the Brain: 

  • The son (LB) and his father (VP) generate multiple decisions on the interaction using logic and past data respectively, out of which…
  • The father (VP) judges which decision is suitable for execution using simple logic
  • The father (VP) takes his son's (LB's) assistance to scrutinize the logic used for the suitable decision
  • The son (LB) contributes when required with thorough logic
  • The father (VP) continues processing decisions until his son (LB) finds the logic valid, upon which…
  • The father (VP) finalizes the decision for execution
  • The son (LB) executes the finalized decision as and when required, in which…
  • The father (VP) guides his son (LB) in execution if physical actions are involved
  • The son (LB) executes preset physical actions on his own when either a preset condition is reached or it is instigated by his father (VP) to do so

Besides the above, LB and VP share a deep partnership where, e.g. in recognising a person, LB searches the facial database while VP simultaneously fetches the emotional information connected to it. It is because of such deep partnerships that it becomes difficult to detect their roles using imaging and other techniques.

Fundamental Mind Related Phenomena Simplified by the Model 

VP is what we refer to as "self" and LB is our non-conscious mind

Thoughts are communication within and between VP and LB

Decisions result out of VP's processing with LB and/or itself

Judgments are decisions finalized by VP

Intentions are action plans based on VP's finalized decisions

Attention is about the topic that is being processed by VP

Free Will is enabled by VP's flexibility to judge and finalize solutions empowered by its wisdom

Intentionality (philosophy of mind) is the intention of VP-LB communication

What are LB & VP: 

LB, short for Logical Brain, is a functional component of mind working in parallel processing environment, which resides in the interaction processing areas of the left hemisphere in a majority of population. It contains repetitive, preset and static information which can be randomly accessed. VP, short for Virtual Person, is a functional component of mind working in serial processing environment, which resides in the interaction processing areas of the right hemisphere in a majority of population. It contains hierarchical database of information from past experiences that can be accessed by serial navigation.
