I am studying the concept of multi-tasking. The premise upon which I am asking this question is my belief that multi-tasking is a myth(as discussed in a few books on the same topic) and that the brain processes its tasks/brain requests sequentially, one by one. The moment we try doing two tasks, that interfere with each other in terms of the areas of brain that are activated while doing those tasks, we hit an efficiency bottleneck; our efficiency of brain resource usage goes down.
The same belief now led me to think that an efficient way of performing any task is to schedule the task in the brain in such a way that its adjacent tasks have no chance to interfere with the current task in terms of their usage of brain's resources. So, what are those different brain resources that together accomplish an activity? Can anybody give me a full list of the abilities of the brain as per the latest scientific results available?
In the process I tried to list down the various activities that we enjoy doing while we are able to give our full attention/concentration to them and then tried to see what are the varieties of things that a brain can actually do, so that we can quickly identify the activity and classify it in terms of its effect on brain's usage.
A few significant things brains beautifully do are:
calculations(math) = counting
Literature = imagination + verbal
music skills = counting + aesthetic
learning new language = memory + verbal usage + pattern detection
falling in love = reproductive + courting
imagery and sexual fantasy = reproductive + visual imagination + aesthetics
poetry = verbal + counting(metre) etc
traveling = recall + curiosity
adventure = same as above
sports = strategy + motor skills etc etc etc
The above list includes the types of creative activities that brain does, but does not list the basic, elementary set of abilities that together accomplish these activities. So my question here is, what are those various distinct faculties that a brain uses to accomplish a task? You may provide a list of all the faculties(RHS of the above "so called" equations :)), or map the different parts of brain with unique abilities, or provide a totally different way of looking at the brain altogether...
For more clarity:
As an analogy with a computer system which has processing units and related resources like ALUs, Memory, etc what are the different processing unit and resources in the brain which together accomplish a task. I am looking for that list basically
