    Parallel
In summary, the brain is a massively parallel device with no central processor or chief executive. However, the cortex is organized hierarchically with ascending and descending neurons and association areas, particularly the prefrontal regions. While some may argue that the prefrontal cortex is the center of the human neocortex, neuroscience suggests that it is responsible for working memory and only a small portion of our behavior. The role of consciousness in this hierarchy is still up for debate. Additionally, the brainstem plays a crucial role in maintaining and constructing the brain through the use of the ventricle system.

Brain is a massively parallel device,there is no central processor, no chief executive that oversees all cortical areas.
But then again the cortex is very hierachially, there are ascending and descending neurons and it has association areas, most eminent the prefrontal regions.

So what's 'truer'? What keeps us from saying that the prefrontal cortex is the chief executive, the center of the human neocortex?

Hi,

What keeps us from saying that the prefrontal cortex is the chief executive?

Actually neuroscience says that it is because its working memory.
Massively parrallel but many centres are interconnected and may override old centres by newer ones.
Some neuroscientists expect/suppose that 80% of our behaviour is automated...

now are we talking about consciouness or the hardware behind the brain?

if its consciousness then the PFC/HC//PPC drive planning/memory/imagery when the child has grown to a significant age(2-5). Before that who knows if a CEO exists

..as for the driving of the hardware maintaining the brain and creating it...there is a place(?brainstem?)...and it uses the ventricle system to build the brain.

Hi,
I think that Ratzinger was talking about "hardware"?
Consciousness is another affair which may be first defined.
 

What is the difference between parallel and hierarchy processing in the brain?

Parallel processing refers to the simultaneous processing of multiple pieces of information by different parts of the brain. Hierarchy processing, on the other hand, involves the sequential processing of information by different levels of the brain, with higher levels exerting control over lower levels.

Which brain regions are involved in parallel and hierarchy processing?

The prefrontal cortex is primarily responsible for hierarchy processing, while parallel processing involves various regions such as the occipital, parietal, and temporal lobes.

What are the advantages and disadvantages of parallel and hierarchy processing?

Parallel processing allows for faster and more efficient processing of multiple inputs, but it can also lead to distractions and difficulty in focusing on a single task. Hierarchy processing allows for better control and organization of information, but it can also be slower and more limited in its ability to process multiple inputs.

How do parallel and hierarchy processing contribute to overall brain function?

The combination of parallel and hierarchy processing allows the brain to efficiently process and integrate information from various sources, allowing for complex tasks and decision making. It also allows for adaptability, as different processing styles can be utilized depending on the situation.

Is one type of processing more important than the other?

Both parallel and hierarchy processing are essential for overall brain function and cannot be directly compared in terms of importance. They work together to allow the brain to perform a wide range of tasks and adapt to different situations.
