Abstract We show the theory of formal ultradifferentiable normalization. The tools utilized here are KAM methods and Contraction Mapping Principle in Banach space fixed with weighted norms.

We examined how the ginseng extract (GE) acts on the antinociceptive effect induced by footshock (FS)-, psychological (PSY)- and forced swimming (SW)-stress (stress-induced analgesia, SIA), and also on the suppression by FS- and PSY-stress of the development of tolerance to morphine in mice. Neither an acute treatment nor 5 daily pretreatments with GE at 100 mg/kg, p.o. affected each SIA. Pretr...

Normalization, which divisively scales neuronal responses to multiple stimuli, is thought to underlie many sensory, motor, and cognitive processes. In every study where it has been investigated, neurons measured in the same brain area under identical conditions exhibit a range of normalization, ranging from suppression by nonpreferred stimuli (strong normalization) to additive responses to comb...
