Transient attenuation of CO2 sensitivity after neurotoxic lesions in the medullary raphe-area in awake goats.

Hodges MR, Opansky C, Qian B, Davis S, Bonis J, Bastasic J, Leekley T, Pan LG, Forster HV (2004) Transient attenuation of CO2 sensitivity after neurotoxic lesions in the medullary raphe-area in awake goats. J Appl Physiol 97(6):2236-2247. doi: 10.1152/japplphysiol.00584.2004

Summary: The authors wished to investigate the influence medullary raphe-area neurons have on breathing. This control may be through CO2/H+ chemoreceptors and/or through non-chemoreceptor modulation. 1 or 10 ┬Ál of 50 pM SP-SAP (Cat. #IT-07) or Saporin (Cat. #PR-01) was injected into the raphe of goats. Breathing and CO2 sensitivity were evaluated during different physiologic conditions. The data suggest that SP receptor- and glutamate receptor-expressing neurons in the medullary raphe both influence CO2 sensitivity, but not altered breathing periods.
