Pinky and the Brain on the way

Using human brain cells to make mice smarter

This article starts:

Glial cells – a family of cells found in the human central nervous system and, until recently, considered mere "housekeepers" – now appear to be essential to the unique complexity of the human brain. Scientists reached this conclusion after demonstrating that when transplanted into mice, these human cells could influence communication within the brain, allowing the animals to learn more rapidly.

Dear Scientists:  we are not entirely convinced that making mice smarter via human brain cells is a good idea.

Yours kindly,

The Public.
