Effect of lactation on spontaneous IPSC bursts in MNCs. (A) Representative recording of bursts of IPSCs in an unidentified MNC from a lactating rat before and after the addition of TTX. (B) Time histogram of the instantaneous IPSC frequency recorded in representative MNCs. IPSC bursts are indicated by a sharp rise in instantaneous IPSC frequency; they occur with a higher incidence in the MNC from a lactating rat (arrows, lower) than the MNC from a non–lactating rat (arrows, upper). (C) Average incidence of bursts of IPSCs (bursts/h) in MNCs from virgin and lactating rats. (D) Percent of MNCs displaying IPSC bursts (% cellsburst) in virgin and lactating rats. (E) Average incidence of bursts of IPSCs (bursts/h) in MNCs from non–lactating and lactating rats in the presence of TTX to block spiking. (F) Percent of MNCs displaying IPSC bursts in virgin and lactating rats in the presence of TTX. The numbers in the columns in all the figures represent the numbers of recorded cells in the averages. *, P < 0.05.
