Relationship between PO-AH and PHA in the effects of EA at neiguan in the rabbit.
The activity of PHA neurons was extracellularly recorded by using glass microelectrodes and the mutual relationship between PO-AH and PHA during the regulation activity of EA was analysed. The results were as follows: 1. The activity of most PHA neurons could be changed by PO-AH stimulation. 2. The activity of some PHA neurons could be affected by AMI. 3. The AMI-induced PHA neurons activity could be changed by EA at "Neiguan". 4. The effect of EA could be enhanced in some PHA neurons by PO-AH stimulation under EA. The findings suggest that PO-AH and PHA possess some coordination effect in the regulation of EA at "Neiguan" on the functional activity of the heart.
