Ranked Claims
Novel magnetic resonance imaging applications combined with pupillometry have opened the way to evaluate locus coeruleus activity in vivo.
novel magnetic resonance imaging applications combined with pupillometry have opened the way to evaluate LC activity in vivo
DREADDs and optogenetics helped redefine the locus coeruleus from a homogeneous structure to a functionally heterogeneous system.
novel research tools are now available that have helped redefine the LC system, moving away from the traditional view of LC as a homogeneous structure that exerts a uniform influence on neural activity. Indeed, innovative techniques such as DREADDs (designer receptors exclusively activated by designer drugs) and optogenetics have demonstrated the functional heterogeneity of LC
