Figure 4From: The sweet taste quality is linked to a cluster of taste fibers in primates: lactisole diminishes preference and responses to sweet in S fibers (sweet best) chorda tympani fibers of M. fascicularis monkeyAverage response profiles of from the top the N cluster, H cluster, Q cluster and S cluster. Error bars are SE. Dark columns, the tastants without lactisole, open columns, tastants with 1.25 mM lactisole added. Asterisks denote a difference between the two columns at a significance level of > 90%. Only the responses to sweeteners in the S fiber cluster were significantly suppressed by the addition of lactisole.Back to article page
