DOI: 10.1002/glia.24370
Abstract: Neurovascular coupling (NVC) modulates cerebral blood flow to match increased metabolic demand during neuronal excitation. Activation of inhibitory interneurons also increase blood flow, but the basis for NVC caused by interneurons is unclear. While astrocyte… read more here.

DOI: 10.1007/s00421-017-3707-9
Abstract: PurposeModels designed to study neurovascular coupling (NVC) describe a possible cerebral hemisphere dominance dependent on task completed and preference in handedness. We investigated whether passive arm manoeuvre performed with dominant (Dom-Arm) or non-dominant arm (ND-Arm)… read more here.

DOI: 10.1007/s11682-021-00588-4
Abstract: Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a recently identified autoimmune disorder with heterogeneous neurological, psychiatric, and cognitive manifestations. The NMDAR is a key signaling node for neurovascular coupling, the mechanism by which cerebral blood perfusion is… read more here.

DOI: 10.1007/s12975-017-0585-8
Abstract: Impaired cerebral autoregulation and neurovascular coupling (NVC) contribute to delayed cerebral ischemia after subarachnoid hemorrhage (SAH). Retinal vessel analysis (RVA) allows non-invasive assessment of vessel dimension and NVC hereby demonstrating a predictive value in the… read more here.
