Both animals had been delivered by caesarean section and were recently exposed to such potent vasoactive substances as oxytocin, ergonovine, and norepinephrine.
Low electrodermal activity is also assumed to reflect a pathway from low norepinephrine and low serotonin to brain functioning.
As a result, responsive to norepinephrine than arteries from denuded arteries from pregnant animals are more nonpregnant animals.
Although both methylphenidate and amphetamines inhibit reuptake of dopamine and norepinephrine, only amphetamines also promote release of those neurotransmitters.
The results obtained suggest that noradrenaline (norepinephrine) could be one of the factors responsible for the metabolic behaviour that characterises cytoplasmically immature oocytes.
The norepinephrine and serotonin systems spread throughout the brain, while dopamine circuits are more specifically targeted.
A neuroscience account of aversive conditioning might refer to the amygdala and temporal cortex and perhaps the role of neurotransmitters such as norepinephrine.
However, cyclooxygenase inhibition had no effect on the norepinephrine contraction responses.
