Emotional arousal, mediated by the amygdala, is known to modulate episodic memories stored by the hippocampus, a region involved in pattern separation the process by which similar representations are independently stored. Significance va3 evaluated with a two-sample permutation test Good, implemented in Matlab MathWorks. We also hypothesized that the amygdala would show emotional modulation effects.

Pattern Separation of Emotional Information in Hippocampal Dentate and CA3

Distinct ensemble codes in hippocampal areas CA3 and CA1. To determine if our emotional discrimination task may provide a sensitive measure of medial temporal lobe changes in disorders of mood and memory, we tested a small sample of individuals experiencing depressive symptoms on the emotional discrimination task.

Dendritic mechanisms underlying rapid synaptic activation of fast-spiking hippocampal interneurons. The force applied by the diamond knife during the cutting of serial EM sections compresses the sections depending on the type of resin, knife angle, and cutting speed.

The EM sampled dendritic diameters were smaller, on average, than those obtained using Neurolucida. Gap junctions linking the dendritic network of GABAergic interneurons in the hippocampus. 33110 2, revised ed Springer; New York: This area is important for the fast encoding and consolidation of memory traces Nakazawa et al.

The mediolateral and anteroposterior extents were 0. There was no correlation between amygdala activity 330 depressive symptoms. The parameters of the measured prolate ellipsoids were the following: Handbook of brain microcircuits.

Synaptic target selectivity and input of GABAergic basket and bistratified interneurons in the CA1 area of the rat hippocampus. A frequency-dependent switch from inhibition to excitation in a hippocampal unitary circuit. To examine emotional modulation of memory at the level of hippocampal subfields, we used high-resolution fMRI 1. Thus, gaining a clearer understanding of amygdala-hippocampal interactions in humans will advance our knowledge of the neurobiological mechanisms underlying such abnormalities.

Materials and Methods All animal procedures were performed in accordance with the Animals Scientific Procedures Da3, United Kingdom and associated regulations.

Complementary roles of cholecystokinin- and parvalbumin-expressing GABAergic neurons in hippocampal network oscillations. Since our positive stimuli were not as arousing as negative stimuli, xa3 opted not to include positive trials in our fMRI analyses.

Pattern Separation of Emotional Information in Hippocampal Dentate and CA3

Sharp wave-associated high-frequency oscillation Hz in the intact hippocampus: Pattern separation in the dentate gyrus and CA 3 o the hippocampus. Accuracy of tetrode spike separation as determined by simultaneous intracellular and extracellular measurements. Amygdala activity related to enhanced memory for pleasant and aversive stimuli.

Analysis of oscillations Spike timing, determined by thresholding, was related to oscillations in various frequency bands, as described previously Klausberger et al. Therefore, the major and minor diameters of dendritic ellipse profiles were expanded accordingly using a factor of 1. Analysis of low similarity stimuli could be interesting as well, although different neural mechanisms may be at play when interference is not maximized.

For the estimation of dendritic surfaces for 3310 cell, dendritic diameters were measured using the Neurolucida Explorer software. Oscillations of the LFP in various o bands are correlated to behavioral states: Evaluation of 14 nonlinear deformation algorithms applied to human brain MRI registration. GABA-containing neurons in the septum control inhibitory interneurons in the hippocampus.

Increased amygdala response to masked emotional faces in depressed subjects resolves with antidepressant treatment: See other articles in PMC that cite the published article. These results indicate c3 although PV-expressing basket cells may be involved in the generation of local ripples in CA3, probably through their influence on somatic membrane currents and thus pyramidal cell firing, this signal does not influence the downstream CA1 network to an extent that would be detectable.

Informed consent was obtained from all participants, with all procedures approved by the Johns Hopkins University Institutional Review Board. This absence of evidence should not be taken as evidence of 33310 and we realize that there are likely gender differences here that need to be considered in future experiments.

Thus, our analyses compared the following conditions: 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.
