The maximal extents of these areas in the CA1—CA3 and anteroposterior axes were used as metrics for their characterization.

Spike train timing-dependent associative modification of hippocampal CA3 recurrent synapses by mossy fibers. The medial temporal lobe.

Theta and gamma coordination of hippocampal networks during waking and rapid eye movement sleep. The following steps were used: In H—Jthe number of spikes troughs per bin were normalized to the total number of recorded spikes troughs for that cell.

Although the data from high similarity items alone 331 a trend towards an emotional i 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. Subsequently we cut another part of this layer parallel with its surface completely on an ultramicrotome into n EM sections.

Measuring lateral tissue shrinkage of the vibratome sections To estimate the dimensions of the cells in the perfusion fixed brain, the measurements obtained in the HRP-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

The reconstruction was rotated to provide a view approximately perpendicular to the laminar boundaries axonal sections. Functional images were collected using a high-speed EPI single-shot pulse sequence 1. In fact, five of six cells fired on virtually every episode; only one 33310 J76b fired on a minority of episodes 21 of The total surface of all dendritic segments in a layer was estimated using their dimensions measured with Neurolucida after the diameters were corrected for over estimation due to diffraction see Materials and Methods.

The sections were compressed to In the current study, we utilized high-resolution fMRI to test hypotheses about specific subfields of the hippocampus and their involvement in the pattern separation of emotional stimuli. Oscillation cycles were defined as intertrough intervals in the filtered signals digital bandpass finite impulse response filters. Briefly, we computed the convex hull CH and the angles of the CH edges of the tree.

Note the resulting formula for S i depends only on the measured variable D i. For all dendritic sections, the 33100 shrinkage in X, Yand Z dimensions was corrected using the calculated appropriate shrinkage factors depending on the method of processing, as described above.

Dendritic surface area per layer calculated. Emotion and episodic memory in neuropsychiatric disorders. Cholinergic induction of network oscillations at 40 Hz in the hippocampus in vitro.

Participants underwent an incidental encoding phase where they were shown emotional and non-emotional images, presented in randomized order, and were asked to rate the images for emotional valence negative, neutral, and positive. This served to remove voxels that did not respond i any of the task conditions so that the analyses can be more sensitive to subtle changes across conditions.


Synapses arrows were counted boutons, asterisks.

Mean ripple amplitude was computed based on the absolute amplitude for all troughs occurring during selected ripple episodes. The impact of emotional arousal on hippocampal pattern separation has not been examined in detail in humans. BCPhase distribution histograms for spikes from two PV-basket cells and one putative pyramidal cell.

Distinct nonuniform cable properties optimize rapid and efficient activation of fast-spiking GABAergic interneurons.

Discovering endophenotypes for major depression. Distinct timing in the activity of cannabinoid-sensitive and cannabinoid-insensitive basket cells. When all recorded PV-expressing basket cells were considered as a population, they also fired APs in a significantly phase-locked manner around the trough of CA3 ripples, but not related to CA1 ripples Fig. Theta oscillations were detected within episodes of at least 6 s 2 s for J31a where the ratio of power root mean square amplitude; 2 s windows in the theta 3—6 Hz to delta 2—3 Hz frequency bands exceeded four.

COnly a small proportion of thedendritic trees of basket cells in the CA1 area is in str. 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.
