Exempel på norepinephrine

• It is unclear where on the norepinephrine dose-response curve the level of active tone was set.

• The contraction responses to norepinephrine increase in some arteries and decrease in others during pregnancy.

• Even in humans, blocking norepinephrine reduces the memory enhancing effects of surprise.

• Prior exposure to chronic stress results in enhanced synthesis and release of hippocampal norepinephrine in response to a novel stressor.

• These overall effects were reversible, as the frequency of oscillation returned to baseline during washout of norepinephrine.

• One involves primarily the norepinephrine system projecting from the locus coeruleus to the prefrontal and posterior cortex and hippocampus.

• The effect of norepinephrine on blood flow throught the fetal liver and ductus venosus.

• However, cyclooxygenase inhibition had no effect on the norepinephrine contraction responses.

• A neuroscience account of aversive conditioning might refer to the amygdala and temporal cortex and perhaps the role of neurotransmitters such as norepinephrine.

• The norepinephrine and serotonin systems spread throughout the brain, while dopamine circuits are more specifically targeted.

• The results obtained suggest that noradrenaline (norepinephrine) could be one of the factors responsible for the metabolic behaviour that characterises cytoplasmically immature oocytes.

• Although both methylphenidate and amphetamines inhibit reuptake of dopamine and norepinephrine, only amphetamines also promote release of those neurotransmitters.

• As a result, responsive to norepinephrine than arteries from denuded arteries from pregnant animals are more nonpregnant animals.

• Low electrodermal activity is also assumed to reflect a pathway from low norepinephrine and low serotonin to brain functioning.

• Both animals had been delivered by caesarean section and were recently exposed to such potent vasoactive substances as oxytocin, ergonovine, and norepinephrine.
