And with good rea­son: It has around 86 bil­lion neu­rons and sev­er­al hun­dred thou­sand miles of axon fibers con­nect­ing them.

Helping young brains fight off anxiety by training and raising cognitive control

Anx­i­ety is one of the most com­mon child­hood men­tal dis­or­ders. About 7% of chil­dren suf­fer from it at any giv­en time, with near­ly 1 in 3 ado­les­cents expe­ri­enc­ing it some­time dur­ing their teen years.
