Perivascular Nerves<br />
• Perivascular nerves release various<br />
neurotransmitters and peptides, including 5-HT (Reinhard<br />
et al., Science, 1979, 206: 85)<br />
• Perivascular nerves contain catecholamines, but<br />
vasoconstriction from norepinephrine is poor across<br />
species, including humans (Bevan et al., Stroke, 1998, 29: 212.)<br />
• Interestingly, perivascular sympathetic nerves take<br />
up serotonin both in vitro and during the early phase<br />
of subarachnoid hemorrhage (Szabo et al., Stroke, 1992, 23: 54.)
