About the Cover
Cover picture: Palatability is a key determinant of
food intake. Two distinct classes of firing patterns
(heat maps) in the nucleus accumbens are proposed
to guide consummatory behaviors related to
palatability. Heat maps show neural activity during
consumption of a sucrose reinforcer (red line indicates
onset of consumption), time-averaged over repeated
reinforcer presentations. Hot colors show high firing
rates; cool colors show low firing rates. Inhibitions
(top) occurring before and during consumption are
proposed to gate the onset of feeding bouts, whereas
palatability-driven excitations (bottom) may prolong
bout duration. For details, see the article by Taha and
Fields in this issue (pages 1193-1202.
