Taste Familiarity
GC units signal taste familiarity at a delayed temporal phase of the response. An analysis suggests that specific neuronal populations participate in the processing of familiarity for specific tastants. Furthermore, the neural signature of familiarity is correlated with familiarization with a specific tastant rather than with any tastant. This signature is evident 24 hours after initial exposure. This persistent cortical representation of taste familiarity requires slow post-acquisition processing to develop. This process may be related to the activation of neurotransmitter receptors, modulation of gene expression, and posttranslational modifications detected in the insular cortex in the first hours after the consumption of an unfamiliar tastant.

Famous quotes containing the words taste and/or familiarity:
“There is too much sour grapes for my taste in the present American attitude. The time to denounce the bankers was when we were all feeding off their gold plate; not now! At present they have not only my sympathy but my preference. They are the last representatives of our native industries.”
—Edith Wharton (1862–1937)
“Adolescents sometimes say...”My friends listen to me, but my parents only hear me talk.” Often they are right. Familiarity breeds inattention.”
—Laurence Steinberg (20th century)
