Lateral hypothalamic (LH) injections of the excitatory neurotransmitter glutamate, or its excitatory amino acid (EAA) agonists, kainic acid (KA), D,L-alpha-amino-3-hydroxy-5-methyl-isoxazole propionic acid (AMPA), or N-methyl-D-aspartic acid (NMDA), can rapidly elicit an intense feeding response in satiated rats. To determine whether the LH is the actual(More)
To determine whether endogenous lateral hypothalamic (LH) glutamate and its N-methyl-D-aspartate (NMDA) receptors might participate in the stimulation of natural eating, LH injection of the NMDA antagonist D-(-)-2-amino-5-phosphonopentanoic acid (D-AP5) was tested in adult male rats for suppressive actions on feeding elicited by 1) NMDA, kainic acid or D,(More)
