d) at least one said substance is stored under one of the followings: an inert atmosphere; under vacuum and a pressure above ambient pressure to prevent reactions during storage;

e) when the at least one substance is administered nasally via the device, a dose-response curve of a concentration of the at least one substance within a brain of the subject is substantially linear and

f) when the at least one substance is administered nasally via the device, a fit of a dose-response curve of a concentration of the at least one substance within a brain of the subject is logarithmic, parabolic, exponential, sigmoid, power-low, or any combination thereof.

8.
