Dichotomized Operating System (DOS) - Introduction

Dichotomized Operating System (DOS) is a system in the brain consisting of two functional components that perform various tasks, either together or on a standalone basis, to benefit from current and future experiences. The model presented here explains how they function and interact with each other to form mind.

DOS consists of two functional components, which I call "Logical Brain" and "Virtual Person". Following are their properties:

Logical Brain (LB) - The non-conscious part of the brain

The Logical Brain, which I will refer to as "LB", is a logical processing component operating in the brain which can access and execute multiple tasks by processing huge amount of data in a parallel processing environment, just like a modern computer (more under title Brain).

It can also accumulate and execute repetitive and condition based operations that are pre-programmed in its biological software (more under title Repetitive Interactions and Condition Based Repetitive Interactions).

It has a databank that contains repetitive, fixed and preset information, which is stored in different locations based on categories.

The processes of receiving sensory inputs and giving out motor commands to the nervous system are done by LB.

It is possible to perform all information processing operations of LB with the current state of the art computer software.

Virtual Person (VP) - "The Self"

The Virtual Person, which I will refer to as "VP", is also a logical processing component operating in the brain like LB, but which includes what I call "B-ROM"*.

B-ROM

B-ROM is a passive system (compared to VP and LB) that is used by VP to process ongoing interactions with its contents for improved, i.e. optimized handling of current and future events, which include summaries of past experiences derived from information gathered and trends encountered in the past and connected to previously stored notions, beliefs, concepts, opinions, etc.

Its database stores information it receives by conceptual hierarchies and links such information by facts, events, perceptions, sensory experiences, emotions, feelings, etc.

Emotions, imagination, motivations, etc. are also processed by VP using B-ROM, as they consider past and/or future data in one way or the other. A major part of perceptions are also processed by VP using data stored in B-ROM (more under title Perception).

Unlike LB, VP can process only one task at a time, i.e. VP is a serial processor (more under title Attentional Limit - in detail)

VP is what you call "self" that distinguishes you from others. It is what you refer to with words like I, me and myself. When it has an experience, you have an experience. When it becomes conscious of something, you become conscious of that thing.

A major part of B-ROM develops in infancy and childhood.

*Why the name B-ROM? I named it B-ROM for Brain-ROM, based on a similar system in the computer called EEPROM (which stands for Electronically Erasable &Programmable Read Only Memory), but in colloquial computer parlance, an EEPROM is called ROM for convenience, and thus, I call it B-ROM. ROM analogy to B-ROM is based on two of it's main features: 1) the feature of ROM supplying information to RAM (Random Access Memory, which is a type of memory that can be randomly accessed) for improved handling of overall operations and 2) The feature of information in ROM (i.e. EEPROM) to be passively changed ( putting it differently, the information stored in ROM can be modified using a special procedure, which is not as frequently and dynamically as RAM).
