Scientists have identified a giant brain within the skin of a mouse, which has been described as the largest brain in the animal kingdom.
The study, which was published in the journal Nature Neuroscience, used a technique called magnetic resonance imaging (MRI) to look at brain tissue from the mice.
“The study reveals an intriguing and novel structure that was previously thought to be only found in the brain of mammals,” lead author Dr Anupam K. Gupta said in a statement.
“We hope this discovery will help us better understand the evolution of the human brain.”
According to Gupta, the structure of the mouse brain was originally thought to only be present in the spinal cord, but researchers discovered that it had been hiding inside the skin and the brain was not a single thing, but rather a network of thousands of interconnected brain cells.
“By understanding the structure, we can better understand how the brain works and how the body regulates it,” Gupta said.
The research was conducted in collaboration with the Medical Research Council (MRC) and the University of Edinburgh.
