“…The anterior insula /frontal operculum represents a primary gustatory area (PGA) (Pribram and Bagshaw, 1954;Benjamin and Burton, 1968;Scott et al, 1986a,b;Yaxley et al, 1990;Hirsch et al, 1994;Cerf et al, 1996;Petrides et al, 1996), and the caudolateral orbitofrontal cortex (CLOF) represents a secondary gustatory area (SGA) (Rolls et al, 1989Baylis and Gaffan, 1991;Rolls and Baylis, 1994;Baylis et al, 1995;Small et al, 1996). Single-cell recording studies indicate that the PGA is not involved in hedonic analysis (Rolls et al, 1988;Rolls, 1993).…”
