![]() ![]() Lou Beaulieu-Laroche, Ph.D., a neuroscientist and the study’s lead author, explained in a recent LinkedIn post: “These findings have important implications for understanding our outstanding cognitive abilities and the challenges therapies derived from animal models face in human clinical trials.”ĭr. Their research appears in a November 2021 edition of Nature. To the surprise of neuroscientists from the Massachusetts Institute of Technology, in Cambridge, and Harvard Medical School, in Boston, this was not the case for human neurons. Typically in mammalian brains, as the size of neurons increases, the density of the ion channels in the neurons also increases. ![]() Neuronal impulses are generated by the activity of ion channels, which control the movement of mineral ions, including potassium and sodium. The human brain contains about 100 billion of these cells. They share information via electrical impulses and chemical signals. ![]() Neurons are the building blocks of the central nervous system, which includes the brain and spinal cord. The neuroscientists’ findings pave the way for future research into the evolutionary forces behind this distinction.The lower density of ion channels may contribute to the more efficient brain function in humans.A group of researchers has discovered that human neurons have significantly fewer ion channels than other mammalian neurons.Share on Pinterest An exciting study finds a key factor that distinguishes human neurons from those of other mammals. ![]()
