Figure 4. Muscimol injection sites inducing paradoxical sleep hypersomnia.

Figure 4

A: Localization on rostro-caudal frontal sections (ß, Bregma) of the Mus injections sites inducing either a PS hypersomnia (black circles), a strong excitation of the animals (grey circles) or no effects on the sleep-wake cycle (empty circles). One circle can represent one or more ejections. B: Percentages of the three vigilance states before and after Mus and NaCl iontophoretic ejections (n = 5) in the vlPAG/dDpMe region. Significance values indicated are: *P<0.05, **P<0.01 and ***P<0.001 vs NaCl.
