Our first aim was to elucidate the mechanisms underlying the hypotensive response elicited by 5-HT(2) receptor activation in the nucleus tractus solitarius (NTS). In pentobarbitone-anaesthetized rats, intra-NTS administration of 2,5-dimethoxy-4-iodoa

Objective : Previous data showed that in the nucleus tractus solitarius (NTS), 5-HT3 receptors are critically involved in the inhibition of cardiac baroreceptor reflex response occurring during the defense reaction. Since stimulation of NTS NK1 recep

International audience; The present study was performed to determine whether or not the increased arterial pressure triggered by 5-HT(3) receptor stimulation in the nucleus tractus solitarii and underlain by a sympathoexcitation is associated with th

In the present study we analyzed effects of bilateral microinjections of muscimol (a GABAA agonist) and baclofen (a GABAB agonist) into the nucleus tractus solitarius (NTS) on bradycardic and pressor responses to chemoreflex activation (potassium cya

The effects of serotonin3 (5-HT3)-receptor stimulation in the nucleus tractus solitarii (NTS) on the cardiovagal, sympathetic, and respiratory responses to activation of carotid body chemoreceptors were investigated in anesthetized rats. The chemoref
