    One line of debate is between two points of view: that of psychological nativism, i.e., the language ability is somehow "hardwired" in the human brain, and usage based theories of language, according to which language emerges through to brain's interaction with environment and activated by general dispositions for social interaction and ...

    en.wikipedia.org/wiki/Acalculia

    Acalculia is associated with lesions of the parietal lobe (especially the angular gyrus) and the frontal lobe and can be an early sign of dementia.Acalculia is sometimes observed as a "pure" deficit, but is commonly observed as one of a constellation of symptoms, including agraphia, finger agnosia and right-left confusion, after damage to the left angular gyrus, known as Gerstmann syndrome.

    This was verified when the right brain of visualisers showed heightened EEG activity when calculating, compared with others using an actual abacus to perform calculations. The abacus can be used routinely to perform addition, subtraction, multiplication, and division; it can also be used to extract square and cube [ 4 ] roots.

    Mere addition paradox: (Parfit's paradox) Is a large population living a barely tolerable life better than a small, happy population?

    Cognitive psychologist Donald D. Hoffman uses a mathematical model based around conscious agents, within a fundamentally conscious universe, to support conscious realism as a description of nature—one that falls within the objective idealism approaches to the hard problem: "The objective world, i.e., the world whose existence does not depend ...

    The idea of an inherited domain-specific basis for arithmetical development is now widely accepted. In his book The Mathematical Brain (1999) he proposed the idea of a 'number module,' an innate, domain-specific mechanism that extracts numerosity from the environment and represents it abstractly, independently of modality and mode of ...

  8. Holonomic brain theory - Wikipedia

    en.wikipedia.org/wiki/Holonomic_brain_theory

    Holonomic brain theory is a branch of neuroscience investigating the idea that consciousness is formed by quantum effects in or between brain cells. Holonomic refers to representations in a Hilbert phase space defined by both spectral and space-time coordinates. [ 1 ]

  9. List of mathematical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_constants

    A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
