This is indeed the case: case reports suggest high neural inertia in at least some narcoleptic human patients (Mesa et al., 2000; Burrow et al., 2005), confirmed by the increased neural inertia observed in rodents with narcolepsy arising from genetic ablation of orexin neurons (Hara et al., 2001; Kelz et al., 2008). Here, HCRT is linked to narcolepsy.
