Abstract Theta oscillations play a major role in temporarily defining the hippocampal rate code by translating behavioral sequences into neuronal representations. However, mechanisms constraining phase timing and cell-type-specific preference are unknown. Here, we employ computational models tuned with evolutionary algorithms to evaluate of individual CA1 pyramidal cells recorded mice rats not engaged any particular memory task. We applied unbiased hypothesis-free approaches identify effects...
Modulation of hippocampal dentate gyrus (DG) excitability regulates anxiety. In the DG, glutamatergic mossy cells (MCs) receive excitatory drive from principal granule (GCs) and mediate feedback excitation inhibition GCs. However, circuit mechanism by which MCs regulate anxiety-related information routing through circuits remains unclear. Moreover, correlation between MC activity anxiety states is this study, we first demonstrate, means calcium fiber photometry, that in ventral hippocampus...
The mechanisms of action many CNS drugs have been studied extensively on the level their target proteins, but effects these compounds complex networks that are composed different types excitatory and inhibitory neurons not well understood. Many currently used anticonvulsant known to exert potent use-dependent blocking voltage-gated Na + channels, which thought underlie inhibition pathological high-frequency firing. However, some GABAergic capable firing at very high rates, suggesting...
A new need is associated with the formation of behaviour directed at its satisfaction. In chronically ethanol-treated rabbits a bodily develops to acquire and consume alcohol. The present study examined firing properties single neurones in cingulate (limbic) cortex rabbits. main questions this were: are there which specifically increase their during alcohol-acquisition (AAB)? What relationship between neuronal mechanisms pre-existing newly formed behaviour? Adult were taught food by pressing...
We have previously shown that both acute and chronic ethanol treatment depresses neural activity, specifically in the cingulate cortex. Minor influences were found motor The effect of hippocampus was intermediate to those cortices. In present study, we concentrate on effects hippocampus. demonstrate how neuronal activity underlying food-acquisition behavior is modified after treatment, subserves formation newly-formed alcohol-acquisition behavior. Neuronal CA1 more sensitive than Dg area....
AMPA and NMDA receptors convey fast synaptic transmission in the CNS. Their relative contribution to output phosphorylation state regulate plasticity. The receptor subunit GluA1 is central Phosphorylation of regulates channel properties trafficking. firing rate averaged over several hundred ms used monitor cellular input. However, plasticity requires timing spiking within a few ms; therefore, it important understand how governs these events. Here, we investigate whether (p-GluA1) alters...
