We have previously found that synaptic pathway from the basolateral amygdala (BLA) to the dentate gyrus (DG) displays N-methyl-D-aspartate (NMDA) receptor-independent form of long-term potentiation (LTP), which should be a valuable model for elucidating neural mechanisms linking emotion and memory. To explore its cellular mechanisms, we investigated(More)

Electrical stimulation of the basolateral amygdala (BLA) evoked synaptic potentials in the dentate gyrus (DG) of the hippocampus in anesthetized rats. To determine if this pathway possesses synaptic plasticity, we investigated the impact of several conditions of high-frequency stimulation on BLA-DG synaptic potentials in these rats. Application of two(More)
We have previously found that the induction of long-term potentiation in the synaptic pathway from the basolateral amygdala to the dentate gyrus (BLA-DG LTP) is regulated by L-type Ca(2+) channels, dopamine D(2) receptors and GABAergic inhibition. In the present study, we investigated possible relations among the three mechanisms by using anesthetized rats.(More)
Although ethanol has been reported to inhibit the induction of long-term potentiation in hippocampal CA1 and dentate gyrus synapses of rats, very little is known about the effect of ethanol on synaptic plasticity in other brain regions. Therefore, in the present study, we investigated the effect of ethanol on long-term potentiation in synaptic pathway from(More)
