Zebrafish blood-brain barrier

Caption

When researchers injected fluorescent dye (blue) into the circulatory system of a zebrafish with a spock1 mutation, the dye leaked out of blood vessels (pink) in the forebrain and midbrain (left), but stayed relatively confined within the hindbrain (right), revealing a blood-brain barrier that was permeable in some areas but not others.
