Augmented hippocampal ripple oscillations in mice with reduced fast excitation onto parvalbumin-positive cells.

Curr Dir Psychol Sci. Population pop phase preferences were computed as the direction of the summed vector of all spikes per cell type.

Regulation of neuronal input transformations by tunable dendritic inhibition.

Some of the cells B15a and J31a had up to five large complex grapelike appendages on their dendrites in stratum radiatum ending into numerous spines Fig.

During theta oscillations, granule cells are hyperpolarized, firing at very low frequencies Ylinen et al. For each layer, the total synaptic 3301 was calculated based on the average synaptic density value of all dendrites measured in that layer. Perisomatic feedback inhibition underlies cholinergically induced fast network oscillations in the rat hippocampus in vitro.

Synchronization of neuronal activity in caa3 by individual GABAergic interneurons. Hippocampal CA3 area generates temporally structured network activity such as sharp waves and gamma and theta oscillations. All participants were right-handed with normal or corrected to normal vision.

Synapses arrows were counted boutons, asterisks. Ca the area of the bounding rectangle for all possible edges, we accepted the minimum one. Since our positive stimuli were not as arousing as negative stimuli, we opted not to include positive trials in our fMRI analyses.

The latter had a minimal bounding rectangle dendritic arbor area of 0. BA putative pyramidal cell B42p identified from a tetrode recording bottom line increased its firing rate during ripple episodes top trace, ripple, filtered, 90— Hz detected from the local field potential in area CA1 middle trace, filtered, 0.

Measuring the thickness of vibratome sections and correcting for shrinkage in the Z dimension We measured section thickness to compensate for changes due to tissue processing. Genetic modifications of PV-expressing cells, some of which are basket cells, have also shown their importance for oscillations and associated cognitive functions Fuchs et al. Because each PV-expressing basket cell innervates hundreds of pyramidal cells Halasy et al.

All animal procedures were performed in accordance with the Animals Scientific Procedures Act, United Kingdom and associated regulations. To estimate the dimensions of the cells in the perfusion fixed brain, the measurements obtained inHRP-reacted, resin-embedded sections needed to be expanded to the dimensions of the freshly sectioned brain.

Pattern Separation of Emotional Information in Hippocampal Dentate and CA3

Altogether, EM sections were counted. The CA3 gamma oscillation frequency seemed to show a higher variability SD range, 7.

This battery was given on the day of the scan, 30 minutes prior to the scanning session. FBasket cell J76a; bottom trace firing is phase-locked to the trough of theta oscillations in CA1 top trace and CA3 middle trace. The same numbers of synapses cz3 also to unprocessed brain, thus dividing the surface values above with the number of synapses results in lower densities. Synapse density values obtained from serial EM samples of individual dendrites Fig.

The role of the human amygdala in emotional modulation of long-term declarative memory.

The surface and length of each sampled dendritic segment was estimated from the sum of the EM sections. Unconscious memory bias in depression: Images were corrected for slice timing and subject motion.

Emotional processing of positive stimuli is an important facet in the modulation of memory Hamann et al. 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.

Immunolocalization of metabotropic glutamate receptor 1a mGluR1a in distinct classes of interneuron in the CA1 region of the rat hippocampus. Although the data from high similarity items alone showed a trend towards an emotional modulation effect, increasing our power by analyzing all similar items both high and low resulted in a significant emotional modulation signal specific to lure correct rejections. Hippocampal CA3 pyramidal cells selectively innervate aspiny interneurons.

Pattern Separation of Emotional Information in Hippocampal Dentate and CA3

We thank Liz Murray and Ayobami Ward for help with participant recruitment and testing. Oscillations of the LFP in various frequency bands are correlated to behavioral states: All participants included in the DS group were medication-free.

Under our conditions the signals considered to result from the primary antibodies were not detected in these reactions. Reductions in DG neurogenesis may also contribute to this effect Dranovsky and Hen, Although the firing rates of basket cells were not affected by the presence of gamma oscillations, their spike timing was clearly related to both CA1 and CA3 gamma oscillations Fig. B13a, minor diameter,
