Supplementary figure 1 The brain region used for the identification of a gene
that controls photoperiodic time measurement by differential subtractive
hybridization analysis (dashed line). Cb: cerebellum; IN: infundibular nucleus;
ME: median eminence; NHPM: nucleus hypothalamicus posterior medialis; OC:
optic chiasm; POA: preoptic area; SCN: suprachiasmatic nucleus; P: pineal
gland.
Supplementary figure 2 Detailed localization of D2 expression in the
mediobasal hypothalamus (MBH). Acute induction of D2 was observed in the
dorsal hypothalamus (DH) around the paraventricular organ (PVO) and lateral
hypothalamus (LHy) in the rostral region (a) and the caudal region (b) of the
MBH. The outline of LHy is shown by dotted circles12. Strong signal was
observed in the infundibular nucleus (IN) and median eminence (ME) under LD
(c). IN and ME are also called basal tuberal hypothalamus (BTH). CO: optic
chiasma; VMN: nucleus ventromedialis hypothalami; DSD: decussatio
supraoptica dorsalis; DMN: nucleus dorsomedialis hypothalami; IH nucleus
inferioris hypothalami;
Supplemental figure 3 Expression of transthyretin (TTR) in the Japanese quail
brain. Strong signals of TTR were observed in the choroid plexus (CP) both
under LD (a) and SD (b), while no signal was detected in the hypothalamus
(arrowhead). No significant difference in the TTR expression between LD and
SD was observed (c) (Mann-Whitney U-test, p>0.05).
