A State of Flux Leaves Teen Brains Sensitive to Experiences

(Left to right) The first panel is an image of an uneven scale, with the blue male symbol weighing heavier than the red female symbol. The second panel features a mouse with a callout depicting various red and blue lines to represent the estrous cycle. In the third panel, there are images of a mouse, marmoset, and cell culture dish. In the final panel, there is an image of therapeutic pills and gears, representing cognitive function, above a balanced scale. Now the male and female symbols are even.
