Scientists Find a Strange New Cell in Human Brains: The 'Rosehip Neuron'

Automatic TRANSCRIPT

Scientists have taken one more small step toward understanding what makes. The human brain unique as NPR's John Hamilton reports they've identified a type of brain cell that exists in people but not in rodents the cells are called rose hip. Neurons and, they were first. Described by scientists. In Hungary named Gabor Thomas Ed. Lean of the institute, for brain science, in Seattle says Thomas was recording electrical signals from cells taken from two human brains in the course of doing these recordings he started. To notice a very distinctive type of cell that's to him, have the shape of, a rose after the pedals have fallen off so he called them they rose upsell meanwhile lean. And other scientists at the Allen institute had also run across these unusual neurons while doing genetic analysis, of the brain cells so the researchers combined with they had learned and lean says their conclusion was remarkable, this particular type of so head properties that had never actually been described in another species today the findings suggest that the human brain is. More than just a big mouse brain at some point it acquired at least one kind of cell mouse doesn't have scientists aren't, sure exactly what these cells do though they seem to be, involved in controlling the. Flow of information in the brain and, lean says their existence has big implications for researchers it throws. Some Doubt on the ability to use the mouse then, to study a certain elements of human function and disease rose hip cells are a type of inhibitory neuron. They act like the brakes in a car telling other brain cells when to slow down and lean says it's possible they play a role. In mental illness these, types of cells, are extremely important and dysfunction of them can actually directly be linked to different types of neuropsychiatric disease like schizophrenia rose hip cells are. Involved in brain disorders it could help explain why so many, brain drugs that work, in mice don't work in people Josh Gordon directs the National Institute of mental health which helped. Fund the research it may be that in order to fully understand psychiatric disorders we need to get, access to these special types of neurons that exist only in humans Gordon says this study is part of, a larger effort by the national institutes of health to identify every type of cell found in the brains of mice monkeys and people we. Don't know how How the brain works if. We don't know all of its parts so in order to describe how the brain produces behavior. We want to know what are the different parts in the brain and then. How they work together new genetic techniques are rapidly improving scientists, ability to detect new types of brain cells and Gordon expects that researchers will find more. Cells that, exist in people but not animals I think it's very very likely that this is the tip of the iceberg the new research appears in the, journal nature
