Current theoretical models describe the brain as a distributed information processing system. This means, in a similar way to a computer, the brain is made of distinct components which are wired together in a tight network of neurons and synapses. Different brain components have different roles or functions. For example, there are areas that are sp...
In the study, the team introduce two key methods of information-processing: redundancy and synergy. Redundant processing is related to interactions that keep multiple copies of the same information in different places. This was found to be common for sensory and motor regions of the brain, where having multiple redundant copies of the same importan...
In comparison to monkeys such as Macaques, the human brain seems to exhibit significantly higher levels of synergy. According to Dr Rosas: “Synergistic relationships are structured in a highly efficient network, which may enable secondary routes of information processing that are not so developed in other primates.” “Therefore, from this study, we ...
Dr Rosas said: “The framework we developed holds the promise of critical new insights into a wide array of neuroscientific questions, from those about general cognition to its disfunctions. Future studies will show, for example, if these new biomarkers of information processing modalities may be helpful in the diagnosis of neurological or psychiatr...
May 18, 2018 · People with a higher IQ are more likely to have fewer connections between the neurons in the outer layer of their brain, according to a recent study. While previous research has suggested bigger brains are indeed smarter, a closer look at the microstructural architecture suggests it's not just a matter of more brain cells, as much as more ...
May 27, 2022 · Synergistic processing is most prevalent in brain regions that support a wide range of more complex cognitive functions, such as attention, learning, working memory, social and numerical...
Dec 4, 2023 · Many neuroscientists suspect that changes to the pattern of connections are more important for the development of human cognition than anything as crude as the brain's volume.
Jun 19, 2017 · Recent genetic evidence suggests the modern human brain is more malleable and is modelled more by the surrounding environment than that of chimpanzees. The anatomy of the chimpanzee brain...
