Which part of the brain controls logic?

Have you ever wondered why some people just seem to make logical decisions so easily, while others struggle with it? The answer lies within our brains – specifically, a specific region called the prefrontal cortex. But what exactly is this area of the brain responsible for when it comes to logic? Let’s find out!

Introduction

The human brain has many regions that specialize in various tasks, from recognizing faces to controlling basic motor skills. One important aspect of our brain function is logic and reasoning, which allows us to solve problems, make decisions, and form judgments based on available information.

So where does the magic happen? It all starts with a tiny part of our brain known as the prefrontal cortex.

What is Prefrontal Cortex?

Located in the front portion of each hemisphere (left and right) in our brains,Prefrontal Cortex is sometimes referred to as “executive control center” because its functions involve decision making, problem solving and complex mental processing among other things

The prefrontal cortex receives inputs from multiple sensory systems including vision hearing touch amongst others . These inputs are then used by circuits within this structure (prefrontal cortex)to generate appropriate responses such as goal-directed behavior , memory retention & recall or inhibitory mechanism ‘

The Anatomy behind Prefrontal Cortex

Although small relative to other areas of the human brain like occipital lobe & cerebral hemispheres,PFC still contains an impressive arrayed subsections defined by both structural qualities like Brodmann areascytoarchitectonic differencesand differing biochemical attributes

  • Dorsolateral prefrontal cortex

    This part specializes in working memory maintenance during high-load conditions

-### Ventrolateral prefrontal cortex
Ventrolateral Pre-frontorla correlates strongly with executive control processes includings inhibition [abilityt o stop unwanted attentional biases]

  • Anterior cingulate cortex

    This part earns its calling as a checking system that detects errors in one’s performance

Prefrontal Cortex and Logic

While scientific research is yet to provide detailed elucidation on this, from what we know so far,newly synthesized information has shown that prefrontal cortex plays an important role in logical thinking.

Studies have shown that patients with damage in the PFC region show reduced abilities to think logically when compared to uninjured persons within the same age bracket.

In addition,PFC-related single unit activity (SUA)correlates significantly with changes in problem-solving behaviour. Increased levels of neural activation can help individuals generate better prolog-like responses & solutions

Further evidence of the correlation between prefrontal connectivity and reaction times was obtained by studying performance scores over time intervals grouped into segments relating specifically individual network modules[Powelle et.. all]

Looking extensively at Language based studies reveal significant correspondence between poor working memory,syllogistic reasoning failures or temporal reconstruction/direction estimation decision tasks(as seen here)

The Role of Right vs Left Hemisphere
Some researchers suggest there are differences between how logic processing occurs on either side of our brain. While not conclusive,it would be interesting to explore these findings nonetheless . In theory,left hemispheric processing imitates a more analytical step-by-step approach while right hemisphere goes creative,affectively-driven thinking thus making left hemispere specialists more suited for strategic planning whilst their right hemisphere counterparts exhibit empathy [Susanna Lunden,Lund University Researcher]

Disorders Associated with Damage to Prefrontal Cortex Region

Damage within this pertinent areaof significance may lead up-to dissociative symptoms depending first upon laterality[i.e right Vs left hemisphere injured] as well the nature and extent of the injury itself Moreover ,it may also result in cognitive behavior defects such as challenges with short term memory, inability to remember directions, inhibit aggressive tendencies or exercise prudence amongst other things.

Here’s a summary table:
| Disorder | Description |
|———————-|————————————————————————————————————|
| Phineas Gage Effect | This unique occurrence led to drastic personality changes caused by an iron bar passing through his PFC. |
| Schizophrenia | Studies have demonstrated that patients suffering from this Pathology exhibit reduced WM capacity || | Without sustained focus on a certain object |
## Factors Impacting Prefrontal Cortex Functions

The functions of Prefrontal Cortex are greatly impacted by
Age
Physical Exercise
Emotional Intelligence

Age is a common culprit for cognitive decline general,but it is particularly so when considering prefrontal cortex .Prolonged engagement within interdisciplinary activities like Sudoku puzzles can help reduce these effects

Physical exercises are believed to benefit workers’ memory function including those associated with prefontal circuits(Small et..all)

In gist studies suggest that physical activity helps promote optimal dopamine neurotransmissionin areas key to execurtive controland thus contribute towards improving your faculties overall

Conclusion

The exact role played by this seemingly small yet significant part of our brain cannot be overstated.Without its executive capabilities we would not be able come up with logical conclusions,inhibit unwatned reflex actions along more exciting feelings occasioned by say introduction of pleasurable stimuli.Thus next time you find yourself struggling through analytical thought or facing challenging problems,its important know where reason and logic emanates -i.e Frontostriatal circuitry/Prefrontal cortex- located at frontal portion of each hemisphere which lies just behind forehead⠀
