  • Hagfish, a group of extant jawless fish, lack true vertebrae, but it is not clear if hagfish lack all vertebrata-like structures. Here the authors report the presence of vertebra-like cartilages in the in-shore hagfish, suggesting that the hagfish underwent secondary reduction of vertebra.

  • Chandelier cells organize neural coding and mediate learning by establishing inhibitory circuit motifs over individual pyramidal neurons and suppressing irrelevant activity via adaptive axo-axonic synaptic plasticity, subserving efficient computation.

  • An analysis of staged hagfish embryos shows that the hagfish adenohypophysis is ectodermal in origin, revealing it to be a developmental quirk unique to hagfishes that was hitherto misleading; from this and other observations a ‘pan-cyclostome’ developmental pattern is derived, indicating that it was primitive for all vertebrates.

  • The brain of the hagfish, a cyclostome related to the lamprey, develops domains equivalent to the median ganglionic eminence and the rhombic lip, resembling the brains of gnathostomes (jawed vertebrates), suggesting that brain regionalization in jawed vertebrates occurred before the divergence of cyclostomes and gnathostomes more than 500 million years ago.
