Our previous studies have demonstrated that gustatory neurons in the parabrachial nucleus (PBN) show altered responses after the acquisition of conditioned taste aversion (CTA) to NaCl. The present study was conducted 1) to examine centrifugal influences on the altered gustatory activity of CTA-trained rats, and 2) to evaluate the role of(More)
In the present experiments, medial prefrontal cortical (mPFC) neurons were extracellularly recorded by means of tetrode electrodes to examine their possible role in the prediction of appetitive reward. Two different cue tones (CS) and sucrose solution or water reward (US) were associated in a Pavlovian conditioning paradigm. In order to test behavioral(More)
The mediodorsal prefrontal cortex (mdPFC), a key structure of the limbic neural circuitry, plays important roles in the central regulation of feeding. As an integrant part of the forebrain dopamine (DA) system, it performs complex roles via interconnections with various brain areas where glucose-monitoring (GM) neurons have been identified. The main goal of(More)
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)

The role of dopamine (DA) receptors in spatial memory consolidation has been demonstrated in numerous brain regions, among others in the nucleus accumbens which innervates the ventral pallidum (VP). The VP contains both D1 and D2 DA receptors. We have recently shown that the VP D1 DA receptor activation facilitates consolidation of spatial memory in Morris(More)
Schizophrenia is a serious neuropsychiatric disorder. Several brain structures, neurotransmitter systems, genetic and environmental risk factors are suspected in the background. Because of its complexity the mechanism of the disorder is not known exactly, so the treatment of patients is unsolved. In the research of schizophrenia application of the rodent(More)

Neurotensin (NT) acts as a neurotransmitter and neuromodulator in the central nervous system. NT is involved in reward and memory processes, drug addiction and also in the regulation of anxiety. The ventral pallidum (VP) receives neurotensinergic innervation from the ventral striatopallidal pathway originating from the nucleus accumbens. Positive(More)
Effects of 6-hydroxydopamine (6-OHDA) lesions in the medial prefrontal cortex with or without protection of norepinephrine (NE) fibers were examined on basic regulatory processes of feeding. Daily body weight, food and water intake were measured. Locomotor activity, ingestion after food or water deprivation, and preference for 5% and 10% glucose solution(More)

The ventral pallidum (VP) is innervated by the mesolimbic dopaminergic system and it has a key role in motivation, reward, and memory processes. Neurotensin (NT) is an important neuromodulator which has been shown to modulate reinforcement in the ventral tegmental area, in the ventral mesencephalic region and in the central nucleus of amygdala. Neurotensin(More)
