Biological Modeling in the Discovery and Validation of Cognitive Dysfunctions Biomarkers
TL;DR: Cognitive disorders are highly heterogenous in terms of symptoms, clinical etiologies, disease progression and therapeutic responses, and their potential biological causes remain largely unknown.

Rhythmic Memory Consolidation in the Hippocampus
Miriam S. Nokia,Markku Peltonen +1 more
TL;DR: It is proposed that in addition to the interplay between neocortical slow oscillations, spindles, and hippocampal sharp-wave ripples during sleep, there are also additional mechanisms available in the hippocampus to control memory consolidation: a rather non-oscillatory hippocampal electrophysiological phenomenon called the dentate spike might provide a means to not only consolidate but to also modify the neural representation of declarative memories.

Alteration of neural oscillations in hippocampal CA3 area in the fast avoidance response rat before and after electric shock avoidance training
Wei-Wei Wang,Dan-Dan Wang,Dan Wang,Yan Guan,Ying-Ying Tang,Zheng Ye,Jing Li,Min Li,Zai-Man Zhu,Qun-Wan Pan +9 more
TL;DR: The results suggest that the increased percentages of β2 and γ1 rhythm and high-level (unchanged) percentage of θ rhythm in the right hippocampus CA3 area might be related to strong spatial cognition ability of fast avoidance response rats.

Inhibiting inhibition: interactions amongst interneurons of the hippocampus
TL;DR: It is shown that functional GABABRs are expressed pre- and postsynaptically in hippocampal GABAergic INs; with distinct populations of INs under differential GABABR control.

Neuronal Oscillations in Cortical Networks
György Buzsáki,Andreas Draguhn +1 more
TL;DR: Recent findings indicate that network oscillations bias input selection, temporally link neurons into assemblies, and facilitate synaptic plasticity, mechanisms that cooperatively support temporal representation and long-term consolidation of information.

Dynamic predictions: Oscillations and synchrony in top–down processing
TL;DR: It is argued that coherence among subthreshold membrane potential fluctuations could be exploited to express selective functional relationships during states of expectancy or attention, and these dynamic patterns could allow the grouping and selection of distributed neuronal responses for further processing.

Phase relationship between hippocampal place units and the EEG theta rhythm
John O'Keefe,Michael Recce +1 more
TL;DR: The phase was highly correlated with spatial location and less well correlated with temporal aspects of behavior, such as the time after place field entry, and the characteristics of the phase shift constrain the models that define the construction of place fields.

Storage of 7 +/- 2 short-term memories in oscillatory subcycles
John E. Lisman,Marco Idiart +1 more
TL;DR: It is shown that activity patterns associated with multiple memories can be stored in a single neural network that exhibits nested oscillations similar to those recorded from the brain.

Mechanisms of Gamma Oscillations in the Hippocampus of the Behaving Rat
TL;DR: This work examines the generation of gamma oscillation currents in the hippocampus, using two-dimensional, 96-site silicon probes and identifies two gamma generators, one in the dentate gyrus and another in the CA3-CA1 regions.
