Essential Role of D1 But Not D2 Receptors in the NMDA Receptor-Dependent Long-Term Potentiation at Hippocampal-Prefrontal Cortex Synapses In Vivo
An intact mesocortical dopaminergic (DA) input to the prefrontal cortex (PFC) has been reported to be necessary for long-term potentiation (LTP) to occur at hippocampal-prefrontal cortex synapses.Expand

Long-Term Depression Induced by Postsynaptic Group II Metabotropic Glutamate Receptors Linked to Phospholipase C and Intracellular Calcium Rises in Rat Prefrontal Cortex
We have previously shown (Otani et al., 1999b) that bath application of (2S,2′R,3′R)-2-(2′,3′-dicarboxycyclopropyl)glycine (DCG IV), the agonist of group II metabotropic glutamate receptors (mGluRs),Expand

Transient Brain Ischaemia Provokes Ca2+, PIP2 and Calpain Responses Prior to Delayed Neuronal Death in Monkeys
To clarify the mechanism of postischaemic delayed cornu Ammonis (CA)‐1 neuronal death, we studied correlations among calpain activation and its subcellular localization, the immunoreactivity ofExpand

Induction of stable long‐term depression in vivo in the hippocampal–prefrontal cortex pathway
We studied excitatory field potentials in the medial prefrontal cortex (mPFC, prelimbic area) to electrostimulation of the ventral hippocampus (CA1/subicular region) in the anaesthetized rat. NineExpand

Cooperativity between hippocampal–prefrontal short-term plasticity through associative long-term potentiation
The hippocampal-medial prefrontal cortex (mPFC) pathway provides highly convergent input to the mPFC in rats and shows two types of short-term plasticity in terms of paired-pulse facilitation (PPF)Expand

Interleukin-1 receptor antagonist inhibits transient increase of plasma corticosterone in the initial phase of trimethyltin-induced hippocampal necrosis.
The temporal increase of plasma corticosterone (CORT) levels at 3 or 4 days after a single oral administration of trimethyltin (TMT) was suppressed by intracerebroventricular administration of theExpand

Specific role of the posterior dorsal hippocampus–prefrontal cortex in short‐term working memory
Working memory in rats involves neural projections from the hippocampus (HP) to the prefrontal cortex (PFC), based on delayed task experiments in a radial‐arm maze, in which the time span of workingExpand

Habituation of lactate release responding to stressful stimuli in rat prefrontal cortex in vivo.
The extracellular level of lactate is mainly dependent on functional glucose metabolism in most brain cells regulated in part by neuronal activity. We investigated the effect of environmental stimuliExpand

Differences between paired-pulse facilitation and long-term potentiation in the dorsal and ventral hippocampal CA1-prefrontal pathways of rats
We studied the interaction between paired-pulse facilitation (PPF) and long-term potentiation (LTP) in the hippocampo-prefrontal cortex (PFC, prelimbic area) pathway, stimulating the ventral orExpand

Comparative induction of long-term depression between dorsal and ventral hippocampal CA1 in the anesthetized rat
We studied whether a protocol reported as in vivo prefrontal long-term depression (LTD) induction protocol, also induced LTD in the anesthetized rat hippocampal CA1, and whether differences in LTDExpand
