    In the book Brain Fiction: Self-Deception and the Riddle of Confabulation, the author indicated that confabulation is not just a deficit of memory; it is something anybody might do, even people with perfectly fine memories and healthy brains.

    PsychCentral identifies two types of confabulation: spontaneous and provoked. A provoked confabulation is when a patient invents an untrue story in response to a question and tends to occur quite commonly among patients with amnesia or dementia. On the other hand, a spontaneous confabulation tends to occur less commonly and involves the telling of an […]

    Wikipedia puts it this way:  In psychiatry, confabulation is a memory error defined as the production of fabricated, distorted, or misinterpreted memories about oneself or the world, without the conscious intention to deceive.

    Karl Bonhoeffer, a German psychiatrist, is credited with coining the term “confabulation” in 1900 to describe a type of memory loss that negatively impacts an individual’s higher-reasoning ability.

The results of the study showed, however, 35 separate facial expression that convey emotions across all cultures studied, and only 8 that are used in almost all of the cultures.

  • Neurogenesis February 7, 2019
    Neurogenesis is the term for forming new cells. The belief has been that neurogenesis in the brain occurs primarily during gestation and perhaps for a short period of time after birth. Because neurons, thinking cells, do not typically multiply and divide as do other cells such as the glial cells, the assumption has been that […]

In adulthood, the average human brain clocks in at about three pounds (slightly more for the average male brain). Compare that with the brain of a sperm whale that can average 18 pounds, or that of an elephant the weight […]
