Thalamic and Entorhinal Network Activity Differently Modulates the Functional Development of Prefrontal-Hippocampal Interactions.

Unlabelled: Precise information flow during mnemonic and executive tasks requires the coactivation of adult prefrontal and hippocampal networks in oscillatory rhythms. This interplay emerges early in life, most likely as an anticipatory template of later cognitive performance. At neonatal age, hippocampal theta bursts drive the generation of prefrontal theta-gamma oscillations.

Essential role for synaptopodin in dendritic spine plasticity of the developing hippocampus.

Dendritic spines are a major substrate of brain plasticity. Although many studies have focused on Ca(2+)/calmodulin-dependent protein kinase II (CaMKII)-mediated regulation of spine dynamics and synaptic function in adult brain, much less is know about protein kinase A (PKA)-dependent regulation of spine shape dynamics during postnatal brain development. Synaptopodin is a dendritic spine associated modulator of actin dynamics and a substrate of PKA.

Cholinergic control in developing prefrontal-hippocampal networks.

The cholinergic drive enhances input processing in attentional and mnemonic context by interacting with the activity of prefrontal-hippocampal networks. During development, acetylcholine modulates neuronal proliferation, differentiation, and synaptic plasticity, yet its contribution to the maturation of cognitive processing resulting from early entrainment of neuronal networks in oscillatory rhythms remains widely unknown. Here we show that cholinergic projections growing into the rat prefrontal cortex (PFC) toward the end of the first postnatal week boost the generation of nested gamma oscillations superimposed on discontinuous spindle bursts by acting on functional muscarinic but not nicotinic receptors.

Coupled oscillations mediate directed interactions between prefrontal cortex and hippocampus of the neonatal rat.

The coactivation of prefrontal and hippocampal networks in oscillatory rhythms is critical for precise information flow in mnemonic and executive tasks, yet the mechanisms governing its development are still unknown. Here, we demonstrate that already in neonatal rats, patterns of discontinuous oscillatory activity precisely entrain the firing of prefrontal neurons and have distinct spatial and temporal organization over cingulate and prelimbic cortices. Moreover, we show that hippocampal theta bursts drive the generation of neonatal prefrontal oscillations by phase-locking the neuronal firing via axonal pathways.

Comparison of cellular mechanisms of long-term depression of synaptic strength at perforant path-granule cell and Schaffer collateral-CA1 synapses.

This chapter compares the cellular mechanisms that have been implicated in the induction and expression of long-term depression (LTD) at Schaffer collateral-CA1 synapses to perforant path-dentate gyrus (DG) synapses. In general, Schaffer collateral LTD and long-term potentiation (LTP) both appear to be a complex combination of many alterations in synaptic transmission that occur at both presynaptic and postsynaptic sites, while at perforant path synapses, most evidence has focused on postsynaptic long-term alterations. Within the DG, the medial perforant path is far more studied than lateral perforant path synapses, where most evidence relates to the induction of heterosynaptic LTD at lateral perforant path synapses when LTP is induced in the medial perforant path.

Persistent (>24h) long-term depression in the dentate gyrus of freely moving rats is not dependent on activation of NMDA receptors, L-type voltage-gated calcium channels or protein synthesis.

Hippocampal long-term depression (LTD) comprises a persistent reduction of synaptic strength that is typically induced by low frequency stimulation (LFS). Although LTD has been described for the dentate gyrus in vitro, this phenomenon in the dentate gyrus of the intact animal is less well understood. In the current study, we investigated the contribution of NMDA receptors, L-type voltage gated calcium channels and protein synthesis to LFS-induced LTD in the dentate gyrus of freely moving rats.

Group II mGluR-induced long term depression in the dentate gyrus in vivo is NMDA receptor-independent and does not require protein synthesis.

Long term depression (LTD) can be induced by low frequency stimulation (LFS) as well as by agonist activation of neurotransmitter receptors. Group II metabotropic glutamate receptors (mGluRs) play an essential role in the regulation of electrically-induced LTD in the hippocampus in vivo: LTD is inhibited by antagonists, and enhanced by agonists of group II mGluRs. Here we investigated induction of LTD by activation of group II mGluRs as well as the cellular mechanisms which might mediate group II mGluR-induced LTD.

The metabotropic glutamate receptor mGluR3 is critically required for hippocampal long-term depression and modulates long-term potentiation in the dentate gyrus of freely moving rats.

Group II metabotropic glutamate receptors (mGluRs) play an important role in the regulation of hippocampal synaptic plasticity in vivo: long-term potentiation (LTP) is inhibited and long-term depression (LTD) is enhanced by activation of these receptors. The contribution, in vivo, of the individual group II mGluR subtypes has not been characterized. We analysed the involvement of the subtype mGluR3 in LTD and LTP.

High frequency oscillations in the dentate gyrus of rat hippocampal slices induced by tetanic stimulation.

Tetanic stimulation induces high-frequency network oscillations in area CA1 and in the subiculum of rat hippocampal slices. Here, we describe the effects of similar tetanic stimulation in the molecular layer of the dentate gyrus. We found field potential oscillations in the dentate granule cell layer which shared several properties with tetanically induced oscillations in CA1, including delayed onset, duration, progressive slowing of frequency within the oscillations and sensitivity to blockers of GABA(A) receptors, NMDA receptors and metabotropic glutamate receptors.

Glutamate-induced gamma oscillations in the dentate gyrus of rat hippocampal slices.

In this paper we show that gamma oscillations can be elicited by brief (< or = 200 ms) local applications of glutamate in the dentate gyrus of rat hippocampal slices. Dentate gamma oscillations show an initial peak frequency of approximately 70 Hz and last for up to 4 min. The network activity involves functional GABA(A) receptors as it is drastically reduced by GABA(A) receptor antagonists.

Growing familiarity with the test situation augments the vigilance deficit of aged rats.

Quantitative EEG profiles of aged and of young-adult Fisher-344 rats were studied over 10 consecutive recording (3 h) sessions. The individual recording sessions were spaced regularly over a 6-week period. In the aged rats, in recordings from both the frontal cortex and dorsal hippocampus, the EEG characteristics of a vigilance deficit state increased in prominence up through 8 recording sessions before a stable level was reached.

Examination of a series of 8-[3-[bis(4-fluorophenyl)amino]propyl]-1-aryl-1,3,8- triazaspiro[4.5]decan-4-ones as potential antipsychotic agents.

8-[3-[Bis(4-fluorophenyl)amino]propyl]-1-phenyl-1,3,8- triazaspiro[4.5]decan-4-one (3) and related compounds have been shown to have antipsychotic profiles in biochemical and behavioral pharmacological test models. The dose of 3 necessary to produce catalepsy in rats is much greater than that required for activity in behavioral tests predictive of antipsychotic efficacy, for example the suppression of high base line medial forebrain bundle self-stimulation in rats.

Arousal deficit shown in aged rat's quantitative EEG and ameliorative action of pramiracetam compared to piracetam.

The basal EEG profile of the aged Fisher-344 rat was consistently different from that of the young rat, showing dominant high voltage slow-wave components. These slow waves were present in both the frontal cerebral cortex and dorsal hippocampus. Absent or greatly attenuated in the aged rat's hippocampal EEG was rhythmic theta activity, which was always dominant in the young awake rat's hippocampus.

Pharmacologic therapeutic window of pramiracetam demonstrated in behavior, EEG, and single neuron firing rates.

Following oral or intravenous administration, a representative cognition activator drug, pramiracetam sulfate, is shown to have a pharmacologic therapeutic window at three different levels of study: learned behavior, gross EEG activity of the frontal cortex and hippocampus, and firing rate of single hippocampal neurons.

1-[3-(Diarylamino)propyl]piperidines and related compounds, potential antipsychotic agents with low cataleptogenic profiles.

On the basis of a structural model of the postsynaptic dopaminergic antagonist pharmacophore, a series of 1-[3-(diarylamino)propyl]piperidines and related compounds was synthesized and evaluated for potential antipsychotic activity. For a rapid measure of activity, the target compounds were initially screened in vitro for inhibition of [3H]haloperidol binding and in vivo in a test of locomotor activity. Behavioral efficacy of compounds identified from the initial screens was more accurately measured in rats by using a suppression of high base-line medial forebrain bundle self-stimulation test model.

Cognition-activating properties of 3-(Aryloxy)pyridines.

A series of 3-(aryloxy)pyridines was found to possess activity in enhancing retention for passive avoidance learning in mice. This test was used to select compounds with potential therapeutic properties for the treatment of cognitive disorders. Reference drugs that gave positive results in this procedure included d-amphetamine, magnesium pemoline, methyl phenidate, picrotoxin, phenytoin, and ethosuximide.
