11(4):e0151823.
PMID: 27043211
The head region of Hydra, the hypostome, is a key body part for developmental control and the nervous system. We herein examined genes specifically expressed in the head region of...

PMID: 25498132
In our previous studies of the Hydra nerve ring, we proposed the following hypothesis: "The nerve ring in the hypostome of Hydra is a central nervous system (CNS)-like neuronal structure."...

PMID: 23341254
Oocyte maturation and subsequent spawning in hydrozoan jellyfish are generally triggered by light-dark cycles. To examine if the initiation of the maturation process after light stimulus is mediated by neurotransmitters,...

PMID: 19440733
The GLW-amide family is a neuropeptide family found in cnidarian species and is characterized by the C-terminal amino acid sequence -Gly-Leu-Trp-NH(2). To detect mammalian peptides structurally related to the GLW-amide...
