The studies suggest that complete inhibition of MSH liberation from the pars intermedia is brought about in response to the receipt of photic cues through the eyes and, possibly, by the pineal gland. The punctuate condition of epidermal melanophores is brought about by the inhibition of MSH liberation alone, whereas the punctuate condition of dermal melanophores is brought about by the inhibition of MSH liberation and the liberation of melanin aggregating substance from the pineal gland in response to photostimulation.
研究表明,通过眼睛以及可能通过松果体接收到光信号后,垂体中间部的促黑素释放会被完全抑制。表皮黑素细胞的点状状态仅由促黑素释放的抑制引起,而真皮黑素细胞的点状状态是由促黑素释放的抑制以及松果体响应光刺激释放黑色素聚集物质共同引起的。
