Seasonal changes of gene expression of whole brain in Medaka fish (Oryzias latipes) LW

To examine the seasonal transcriptional landscape of medaka brain, we compared the gene expression of whole brain under SC (short-day and cool temperature conditions: 10 h light/14 h dark and 10 °C) and LW (long-day and warm temperature conditions: 14 h light/10 h dark and 26 °C) conditions. Adult male medaka kept under LW conditions either reimained in LW or were transferred into SC conditions. Two weeks after transfer, whole brains were collected in the middle of the light phase.
