Propagation of specific network patterns through the mouse hippocampus.
TL;DR: Propagation of ripples through the hippocampal loop maintained precise temporal relationships at the network and cellular level, as indicated by coupling of field potentials, multiunit and single cell activity between major portions of CA3 and CA1.

Field Potential Signature of Distinct Multicellular Activity Patterns in the Mouse Hippocampus
TL;DR: Application of unbiased sorting algorithms to sharp wave–ripple complexes in mouse hippocampal slices did indeed reveal the reliable recurrence of defined waveforms that were robust over prolonged recording periods and may be important for cognition-related physiological studies in humans and behaving animals.

Characterization of synchronized bursts in cultured hippocampal neuronal networks with learning training on microelectrode arrays.
TL;DR: Results indicate that firing, association and synchrony of spontaneous bursts in neuronal networks were promoted by learning, and are encouraged to think of a more engineered system based on in vitro hippocampal neurons, as a novel sensitive system for electrophysiological evaluations.
Journal ArticleDOI
The limits of brain determinacy
TL;DR: Developmental stochasticity is sufficiently low to make neurobehavioural defects uncommon, but a chance component of neural development remains, indicating that the authors' brains and behaviour are not entirely determined by a combination of genes-plus-environment.

The Effect of Neural Noise on Spike Time Precision in a Detailed CA3 Neuron Model
TL;DR: This study investigates the spike time precision of a multicompartmental pyramidal neuron model of the CA3 region of the hippocampus under the influence of various sources of neuronal noise, and describes differences in the contribution to noise originating from voltage-gated ion channels, synaptic vesicles release, and vesicle quantal size.

Hippocampus Retains the Periodicity of Gamma Stimulation In Vivo
TL;DR: Using both in vivo intracellular and extracellular recordings from anesthetized rats, it is shown that hippocampal CA1 pyramidal cells can discharge at frequencies determined by the preceding gamma stimulation, provided that the gamma is introduced in theta cycles, as occurs in vivo.
