The triune brain consists of the reptilian complex (basal ganglia), the paleomammalian complex (limbic system), and the neomammalian complex , viewed each as independently conscious, and as structures sequentially added to the forebrain in the course of evolution. According to the model, the basal ganglia are in charge of primal instincts, the ...
MacLean was an American physician and neuroscientist who formulated his model in the 1960s, which was published in his own 1990 book The Triune Brain in Evolution. [1] MacLean's three-part theory explores how the human brain has evolved from ancestors over millions of years, consisting of the reptilian, paleomammalian and neomammalian complexes.
MacLean postulated that the human brain has evolved three components, that evolved successively, with more recent components developing at the top/front. These components are, respectively: The archipallium or primitive ("reptilian") brain, comprising the structures of the brain stem – medulla, pons, cerebellum, mesencephalon, the oldest ...
Clinical lycanthropy is a rare psychiatric syndrome that involves a delusion that the affected person can transform into, has transformed into, or is a non-human animal. [1] Its name is associated with the mythical condition of lycanthropy , a supernatural affliction in which humans are said to physically shapeshift into wolves. [ 2 ]
After the disease had progressed into a larger epidemic, the tribal people asked Charles Pfarr, a Lutheran medical officer, to come to the area to report the disease to Australian authorities. [7] Initially, the Fore people believed the causes of kuru to be sorcery or witchcraft. [35] They also thought that the magic causing kuru was contagious.
The evolutionary history of the human brain shows primarily a gradually bigger brain relative to body size during the evolutionary path from early primates to hominins and finally to Homo sapiens. This trend that has led to the present day human brain size indicates that there has been a 2-3 factor increase in size over the past 3 million years ...
The cerebrum (pl.: cerebra), telencephalon or endbrain [1] is the largest part of the brain, containing the cerebral cortex (of the two cerebral hemispheres) as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system.
People with hyperthymesia also have difficulties letting go of difficult events or traumatic memories, which can stay with them for life. Joey DeGrandis, who was featured in the magazine Time said, "I do tend to dwell on things longer than the average person, and when something painful does happen, like a break-up or the loss of a family member ...
