title: Bimodal effect of 2-deoxy-D-glucose on feeding.
abstract: Perfusion of 2-deoxy-D-glucose (2-DG) into the IIIrd ventricle (i.c.v.) or intraperitoneal (i.p.) injections produced changes in feeding and other overt behavior, as well as indicative changes in electroencephalograms (EEG). Applications of 2-DG, either i.p. or i.c.v., induced hyperphagia within 4 hr which was then followed by hypophagia for at least 96 hr. EEGs evinced low frequency patterns during the lethargy and ataxia symptoms which were present after i.p. injection. After i.c.v. injections, the low frequency EEG during the lethargy and ataxia were not evident. Present results in connection with prior reports indicate that 2-DG has a long term bimodal effect on feeding which may be mediated through central neurons. Hypophagia after peripheral application of 2-DG appeared to be caused at least as much by concomitant traumatism as by effects on neural control of feeding.
