Zielinski MR, & Gerashchenko D. Sleep-inducing effect of substance P-cholera toxin A subunit in mice. (2017). Neurosci Lett, 659 44-47. 09/01.
Objective: To determine the effects of selectively activating SP-expressing brain cells on sleep regulation in mice.
Summary: ICV administration of SP-CTA produces increased amounts of NREM sleep but induces sleep fragmentation.
Dose: 1 mcg/mcl icv.

Objective: To understand central sensitization.
Summary: Findings suggest that central sensitization leads to activation of an endogenous opioid system. Intracisternal administration of SP-CTA is a useful model for studying central sensitization as a disease process without having to induce a peripheral injury.
Dose: SP-CTA was diluted in PBS and injected in a volume of 10 μl (rats) or 1 μl (mice) over the course of three minutes.
