Perisomatic feedback inhibition underlies cholinergically induced fast network oscillations in the rat hippocampus in vitro. The recurrent and commissural CA3 pyramidal cell input to basket cells explains their strong activation and phase locking to CA3 ripples as found here and also in vitro Ellender et al. Future studies investigating the functional connectivity between the amygdala and hippocampal subregions will be important to determine if connectivity between these regions changes as a function of the task.

Dendritic segments from cells B13a and B15a, previously measured by Neurolucida Explorer, were also measured using electron microscopy. Synaptic effects of identified interneurons innervating both interneurons and pyramidal cells in the rat hippocampus. Extracting region of interest ROI voxels We selected voxels for subsequent analyses based on combining the voxels that changed with any of the task conditions in the healthy sample with anatomical ROIs.

Then, we used shrinkage-correction factors to arrive at the dimensions for the freshly cut, fixed brain. This absence of evidence should not be taken as evidence of absence and we realize that there are likely gender differences here that need to be considered in future experiments.

All participants were right-handed with normal or corrected to normal vision. The amygdala modulates the consolidation of memories of emotionally arousing experiences. Handbook of brain microcircuits.

All participants included in the DS group were medication-free. There was no correlation between amygdala activity and depressive symptoms. During the active episodes of of these nine cells, they increased their firing rate from 0. Total number and ratio of excitatory 33100 inhibitory synapses converging onto single interneurons of different types in the CA1 area of the rat hippocampus.

Pattern Separation of Emotional Information in Hippocampal Dentate and CA3

Triton treatment resulted in larger shrinkage in the X, Yand Z dimensions. The cooperation of these areas is important for pattern separation and forming associations Lee et al. Consistent with this, both PV-expressing basket and putative pyramidal cells showed significantly stronger correlation to local CA3 than to CA1 gamma oscillations Fig. The key in C is valid for C—E. These experiments highlight the complexities of emotional modulation of memory and help to tease apart the i underlying the neural mechanisms of amygdala-hippocampal interactions.

In one case B42 the extracellularly recorded and juxtacellularly labeled basket cell was recorded simultaneously with two putative pyramidal cells by tetrodes. Active voxels were selected based on the overall F, agnostic to specific condition or contrast so as not to bias subsequent analyses and remove concerns regarding circularity and double-dipping Kriegeskorte et al.

Dendritic length correlates with the number of synapses received, but the latter strongly depends on the diameter of dendrites and the synaptic cca3 in each layer, which were different. First, after testing phase coupling of basket cell B42c using the second analysis method, we found that the 3310 phase was similar to the local LFP recorded by the glass electrode after artifact removal, and to the LFP recorded by the artifact-free tetrode in CA3.

Altogether, EM sections were counted. A partial flat map was constructed of the dorsal ca from coronal sections immunolabeled for calbindin using an immunoperoxidase method. Their measured parameters are given in Table 1. Planned comparisons were conducted using additional F-tests or t-tests. The CA3 gamma oscillation frequency seemed to show a higher variability SD range, 7.

Pattern Separation of Emotional Information in Hippocampal Dentate and CA3

If one assumes that the strength of AP coupling to the field is indicative of the contribution of a cell to the c3, then it would seem that both CA1 and CA3 theta oscillations are equally determined by PV-expressing basket cells. The number of synapses received by cell B42c was not calculated due to section alignment problems. Unitary inhibitory synaptic potentials in the guinea-pig hippocampus in vitro.
