In a paper published August 27 in the journal Nature Neuroscience, the team said they had discovered a new type of brain cell that has not yet been proven unique to humans but has never been seen in rodents such as mice.
this brain cell is found in the human cerebral cortex and is a special subtype of GABAergic nerve cells in the human cortex.
because of its large "rose crown"-shaped axon-like buckle and tight branch-like structure, the dense beam formed around the center of the cell looks like a rose after a petal has fallen off, so the researchers call it the "rosehip nerve cell."
transcriptomic analysis and morphological physiology studies show that the cell belongs to inhibitory nerve cells.
inhibitory nerve cells act as a brake on the activity of other nerve cells in the brain, while rosehip nerve cells are thought to have effective local control over the calculation of distant dendritic snends of nerve cells in the cerebral cortex.
Although it has not been proven that the brain cells are unique to humans, the researchers say they have never seen them in rodents such as mice, and may be specialized nerve cells found only in the brains of humans or primates.
because there are no such cells in the mouse brain, it is unlikely that simulation scans will be conducted through animal experiments, and the use of human brain samples will undoubtedly make future in-depth research much more difficult.
, researchers don't fully understand the role of these specialized cells in the human brain, or whether they will change during the human disease.
their next step is to look for these cells in other parts of the brain and explore their potential roles in the brain.
