Figure 1. Blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) maps of the same fish.
A: L-serine; B: natal stream water. i: olfactory bulb; ii–iv: telencephalon. The activation map is defined by a threshold of P<0.05 corrected for multiple comparisons using false discovery rate approach. The BOLD signals are overlaid on the anatomical MRI image. Scale bar = 1.0 mm. CB, cerebellum; Dld, dorsal part of lateral area of dorsal telencephalon; Dlv, ventral part of lateral area of dorsal telencephalon; GL, glomerular layer; HL, hypothalamus; OB, olfactory bulb; OT, optic tectum; T, telencephalon.
