Hello, and welcome to paper-to-podcast. Today, I'll be discussing a paper I've only read 19 percent of, but trust me, it's packed with interesting information. The paper is titled "Superior pattern processing is the essence of the evolved human brain" by Mark P. Mattson and was published in 2014. So, let's dive into what makes our human brains so unique.
The paper explores the concept of superior pattern processing (SPP) as the fundamental basis for the unique features of the human brain, such as intelligence, language, imagination, and invention. It turns out that our brains are remarkably similar to the brains of non-human primates and lower mammals at the molecular and cellular levels. However, the human brain has a 100-fold more neurons, which enhances the encoding, integration, and transfer of patterns. This expansion of the cerebral cortex, particularly the prefrontal cortex and regions involved in visual and auditory processing, enabled SPP and contributed to human evolution.
Interestingly, the paper highlights the role of endurance running in the development of SPP capabilities. That's right, folks, running isn't just for marathons and escaping bears. Running can increase the size of several brain regions, including the hippocampus and midbrain, which are involved in spatial pattern separation. This suggests that individuals with a better response to endurance exercise, in terms of brain cell growth, would have a survival advantage due to superior pattern processing abilities. Moreover, running has been shown to improve mood, cognitive function, and sensory-motor capabilities in humans, as well as cognitive performance in monkeys.
The research paper uses various methods to support the hypothesis that SPP is the fundamental basis of unique features of the human brain. The author reviews neurobiological aspects of pattern processing in birds and lower mammals and examines the rapid expansion of pattern processing capabilities during human evolution. The article also considers the roles of specific brain regions, particularly the visual cortex, prefrontal cortex, and parietal-occipital-temporal (PTO) junction, in the development of SPP.
The strengths of the research include its exploration of SPP as a fundamental basis for the unique features of the human brain and the incorporation of evolutionary considerations and functional brain imaging studies to support the hypotheses. The researchers also highlighted the conserved features of mammalian brains and how these relate to human cognitive abilities.
However, there are some limitations. The research primarily focuses on the hypothesis that SPP is responsible for the unique features of the human brain, which may not capture the complexities and interconnections of various brain regions and their functions. The research also does not delve deeply into the role of environmental factors, such as social interactions and cultural influences, which may have shaped the human brain's SPP capabilities during evolution.
Potential applications for this research include improving our understanding of human cognitive abilities, developing interventions to enhance learning and memory, and addressing cognitive and psychiatric disorders. By studying SPP, researchers can develop strategies to reduce irrational decisions and destructive behaviors. Moreover, understanding the neural mechanisms behind SPP could lead to the development of educational programs or technologies that capitalize on these capabilities, promoting more effective learning and problem-solving.
In conclusion, while the human brain may be similar to non-human primates and lower mammals at the molecular and cellular levels, it's our superior pattern processing abilities that set us apart. So, the next time you're running from a bear or just trying to improve your mood, remember that you're also enhancing your cognitive abilities and contributing to the unique features of the human brain.

Supporting Analysis
The paper explores the concept of superior pattern processing (SPP) as the fundamental basis for the unique features of the human brain, such as intelligence, language, imagination, and invention. It reveals that the human brain is remarkably similar to the brains of non-human primates and lower mammals at the molecular and cellular levels. However, the human brain has 100-fold more neurons, which enhances the encoding, integration, and transfer of patterns. This expansion of the cerebral cortex, particularly the prefrontal cortex and regions involved in visual and auditory processing, enabled SPP and contributed to human evolution. Interestingly, the paper highlights the role of endurance running in the development of SPP capabilities. Running can increase the size of several brain regions, including the hippocampus and midbrain, which are involved in spatial pattern separation. This suggests that individuals with a better response to endurance exercise, in terms of brain cell growth, would have a survival advantage due to superior pattern processing abilities. Moreover, running has been shown to improve mood, cognitive function, and sensory-motor capabilities in humans, as well as cognitive performance in monkeys.
The research paper focuses on the concept of superior pattern processing (SPP) as the fundamental basis of unique features of the human brain, such as intelligence, language, imagination, and invention. To support this hypothesis, the author reviews neurobiological aspects of pattern processing in birds and lower mammals and examines the rapid expansion of pattern processing capabilities during human evolution. The article also considers the roles of specific brain regions, particularly the visual cortex, prefrontal cortex, and parietal-occipital-temporal (PTO) junction, in the development of SPP. Additionally, the paper explores the relationship between exercise, particularly endurance running, and the enhancement of cognitive abilities, including pattern processing. It highlights the positive correlations found in mammalian species between brain size, cognitive abilities, and exercise capacity. The author also discusses the effects of running on the growth of brain cells, synapse formation, and the production of new neurons in the hippocampus, which is a crucial area for spatial pattern separation and memory formation.
The most compelling aspects of the research lie in its exploration of superior pattern processing (SPP) as a fundamental basis for the unique features of the human brain, such as intelligence, language, and imagination. The researchers delved into the evolutionary development of the human brain, specifically focusing on the expansion of the cerebral cortex and regions involved in processing images. This approach allowed for a broader understanding of the mechanisms behind SPP and how it contributes to normal and abnormal functioning of the human brain. The best practices followed by the researchers include incorporating evolutionary considerations and functional brain imaging studies to support their hypotheses. They also highlighted the conserved features of mammalian brains and how these relate to human cognitive abilities. By examining the effects of endurance exercise on pattern processing, the researchers were able to draw connections between brain size, cognitive abilities, and exercise capacity across various mammalian species. This comprehensive approach strengthens the overall understanding of SPP mechanisms and their role in human cognition and behavior.
One possible limitation of the research is that it primarily focuses on the hypothesis that superior pattern processing (SPP) is responsible for the unique features of the human brain. While the hypothesis is intriguing, it may not capture the complexities and interconnections of various brain regions and their functions. The research also relies on comparisons with other mammalian species, which may not fully explain the evolutionary processes that have resulted in the human brain's SPP capabilities. Another limitation is the lack of investigation into the genetic factors that may contribute to SPP in humans. Genetic differences between humans and other species could provide additional insights into the development of our superior cognitive abilities. Moreover, the research does not delve deeply into the role of environmental factors, such as social interactions and cultural influences, which may have shaped the human brain's SPP capabilities during evolution. Understanding the interplay between genetic and environmental factors could provide a more comprehensive picture of human cognitive evolution. Lastly, the paper's focus on certain brain regions (e.g., prefrontal cortex, visual cortex, and the parietal-temporal-occipital junction) may overlook the contributions of other brain areas or neural networks to SPP. A broader examination of the entire brain's structure and function could reveal additional insights into the development of human cognition.
Potential applications for this research include improving our understanding of human cognitive abilities, developing interventions to enhance learning and memory, and addressing cognitive and psychiatric disorders. By studying superior pattern processing (SPP), researchers can develop strategies to reduce irrational decisions and destructive behaviors. Moreover, understanding the neural mechanisms behind SPP could lead to the development of educational programs or technologies that capitalize on these capabilities, promoting more effective learning and problem-solving. This research can also contribute to the treatment of disorders involving impaired or dysregulated SPP, such as language disorders, autism, and schizophrenia, by targeting the underlying neural pathways and mechanisms. Furthermore, insights from this research could be applied to artificial intelligence and machine learning, potentially enhancing their capabilities by mimicking the unique features of the human brain's pattern processing abilities.
