Summary
Expert intuition in complex problem-solving relies on the basal ganglia for rapid move selection and the cingulate cortex for strategic decision-making, utilizing ancient brain structures honed through dedicated training.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Expert Performance
Background:
- Intuition enables experts to solve complex problems efficiently.
- Understanding the neural basis of expert intuition is crucial for cognitive science.
Purpose of the Study:
- To investigate the brain activity underlying intuitive decision-making in expert shogi players.
- To identify specific brain regions involved in rapid, expert-level problem-solving.
Main Methods:
- Measured brain activity (fMRI or EEG) of professional and high-level amateur shogi players during gameplay.
- Analyzed neural correlates of rapid move determination and strategic decision-making.
Main Results:
- The basal ganglia are critical for the rapid, intuitive selection of the best next move.
- The cingulate cortex is essential for quick, intuitive strategic decisions (attack/defense).
Conclusions:
- Expert intuition leverages evolutionarily older brain structures, like the basal ganglia and cingulate cortex.
- Long-term, focused training can repurpose these primitive brain areas for sophisticated intuitive decision-making.

01:37Reason and Intuition
7.5K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Chemical reactions often occur in a stepwise fashion, involving two or more distinct reactions taking place in a sequence. A balanced equation indicates the reacting species and the product species, but it reveals no details about how the reaction occurs at the molecular level. The reaction mechanism (or reaction path) provides details regarding the precise, step-by-step process by which a reaction occurs.
For instance, the decomposition of ozone appears to follow a mechanism with two steps:

5.7K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

01:19Mechanism of Conjugation
1.1K
Bacterial conjugation is a mechanism of horizontal gene transfer that enables the exchange of genetic material between bacterial cells through direct contact. This process is facilitated by a donor cell carrying a conjugative plasmid, which encodes genes necessary for pilus formation, DNA replication, and transfer. The conjugative plasmid plays a central role in initiating and executing the transfer of genetic material.The tra region of the conjugative plasmid encodes proteins responsible for...

01:10Mechanism of Angiogenesis
6.9K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Humans have been making ships, shelters, pyramids, weapons, agricultural equipment, and many more items without recording the process or theory behind them for centuries. It would be challenging to document the evolution of mechanics from its origin to the present.
According to records, the history of mechanics starts with Aristotle (384–322 BC). He related mechanics to physical theory, aiming for a universal synthesis.
