The surface of the human brain has many folds (is gyrified), quite unlike the smooth surface of the mouse brain. This gyrification correlates with the increase in size…
Niels Bradshaw (l) and Rich Losick An important question in biology is how genetically identical cells activate different sets of genes. This is particularly perplexing for cells that…
John M. Nicoludis (l) and Rachelle Gaudet As the brain develops, neurons play a complicated game of Twister: they have to keep their neuronal processes from getting tangled…
The holy grail for neuroscientists is to understand how the symphony of activity in our 100 billion neurons acts to control our thoughts and actions. The NIH BRAIN…
Imagine you are a child hoping to get a teddy bear from your parents as a birthday gift. What if they gave you a box of candies instead?…
