Neuromodulators Produce Distinct Activated States in Neocortex

Neuromodulators produce distinct activated states in neocortex.

Neocortical population activity varies between deactivated and activated states marked by the presence and absence of slow oscillations, respectively. Neocortex activation occurs during waking and vigilance and is readily induced in anesthetized animals by stimulating the brainstem reticular formation, basal forebrain, or thalamus. Neuromodulators are thought to be responsible for these changes...

Distinct Activity Profiles of Somatostatin-Expressing Interneurons in the Neocortex

Activated mast cells produce interleukin 13

When mast cells are activated through their immunoglobulin (Ig)E receptors, release of low molecular weight mediators like histamine is followed by secretion of multiple cytokines, including interleukin (IL)-3, IL-4, IL-5, and granulocyte/macrophage colony-stimulating factor. Here we report that stimulated mast cells also synthesize IL-13 mRNA and protein; secretion of this cytokine may be of p...

Neocortex network activation and deactivation states controlled by the thalamus.

Neocortex network activity varies from a desynchronized or activated state typical of arousal to a synchronized or deactivated state typical of quiescence. Such changes are usually attributed to the effects of neuromodulators released in the neocortex by nonspecific activating systems originating in basal forebrain and brain stem reticular formation. As a result, the only role attributed to tha...

Advancements and Refinement in Facial Neuromodulators.

The use of neuromodulators has increased by approximately 748 percent from 2000 to 2014 and has become an integral adjunct for facial rejuvenation. Knowledge of facial anatomy, accurate facial analysis, and familiarity with neurotoxin characteristics will minimize complications and optimize results. Current U.S. Food and Drug Administration-approved neurotoxins in the United States include onab...
