What is a Plezský brain?
, according to the classical brain theory, has the corresponding structure in mammals, including humans, according to classical brain theory. According to the theory "Triune brain", the creeping brain, which concerns instinct and survival, first developed in evolutionary history. Creation, such as mammals, developed more complex brain structures on the base of the Pads brain, allowing thoughts, emotions and confidence. Since then, the brain studies have shown that the theory of Triune's brain is at best too simplified; However, it remains popular with the media and the general public.
During the sixties, the neuroscientist and doctor Paul D. Maclean's research revealed that the basal ganglie, a group of structures at the base of the human brain, resembled lizards and other replils. This, knowing that basal ganglia is strongly involved in motor functions, Maclean led to the belief that the development of the brain corresponded to evolony development. The reptile evolved for the first time in evolutionary history, followed by mammals and then people, so he decided that the brain could also be divided into sectionsWomen on developmental complexity.
In Maclean's theory, basal ganglia, which he called the Plasted brain, he checked basic instincts such as aggression and territoriality, behavior that can be observed in reptiles and mammals, including humans. The intermediate brain structures called the "limbic system" dominated the higher functions necessary for the breeding of young people, but were not necessary for reptiles that generally lay eggs, rather than born and raise the living young. Neocortex, found only in higher mammals, allowed people to develop language, reasoning and conscious thoughts.
The following discoveries in brain and animal science showed that the theory of the Brain Triune is not a model. For example, creatures such as birds are able to use basic tools and language, despite their lack of neocortex. Some brain functions that were once considered to be controlled by the Ploitian brain have been found to include different areas of the brain. Evolutionary inAlso, the eage is not as simple as it once thought, further challenges the Maclean development model.
The brain and the creeping brain remain the accessories of popular culture and beliefs of brain functions. The popular scientific bestseller Astrophysics Carl Sagan "Dragons Eden" gave a wide exposition of brain theory in the 70 years. In his pioneering graphic novel "Elektra Assassin", comic artist Frank Miller gave his character electro the ability to function only with her "plasical brain", which allowed her instinctively and ruthlessly to act in the presence of danger.
