The orbitofrontal cortex (OBF) is known to play important roles in various regulatory processes. Our preliminary behavioral studies showed homeostatic alterations after orbitofrontal cortical microinjection of interleukin-1beta (IL-1beta) in the rat. To elucidate whether the above alterations were due to direct neuronal action of the cytokine, extracellular(More)
Macaque monkeys have a highly evolved visual system comparable to that of humans. One of the important visual functions is performing discriminations among biologically significant objects such as food or heterosexual partners. In the present study, we examined whether rhesus monkeys could categorize two-dimensional images related to food or gender using a(More)
The ventromedial hypothalamic nucleus (VMH) is a central site of action of interleukin-1beta (IL-1beta) induced feeding disturbances. This study was designed to elucidate taste-related perceptual and motivational processes potentially contributing to the anorexia and adipsia seen after bilateral IL-1beta microinjection into the VMH. A saccharin conditioned(More)
The nucleus accumbens, a key structure of the limbic circuitry, is involved in the regulation of motivated behaviors. The accumbens performs its roles via interconnections with brain areas where glucose-monitoring neurons have been localized. To search for such integrative chemosensory cells here, extracellular single neuron activity was recorded in the(More)
To elucidate the homeostatic consequences of direct pallidal administration of interleukin-1beta (IL-1beta), short- (2 h) and long-term (12 h) food intakes, water intake and body temperature were measured after bilateral microinjection of IL-1beta (with or without paracetamol/PAR/pretreatment) into the ventro-medial part of the globus pallidus (GP). The(More)
