Neuronal diversity and temporal dynamics: the unity of hippocampal circuit operations.
TLDR
The spatiotemporal specializations in cortical circuits reveal that cellular diversity and temporal dynamics coemerged during evolution, providing a basis for cognitive behavior.Abstract:
In the cerebral cortex, diverse types of neurons form intricate circuits and cooperate in time for the processing and storage of information. Recent advances reveal a spatiotemporal division of labor in cortical circuits, as exemplified in the CA1 hippocampal area. In particular, distinct GABAergic (γ-aminobutyric acid–releasing) cell types subdivide the surface of pyramidal cells and act in discrete time windows, either on the same or on different subcellular compartments. They also interact with glutamatergic pyramidal cell inputs in a domain-specific manner and support synaptic temporal dynamics, network oscillations, selection of cell assemblies, and the implementation of brain states. The spatiotemporal specializations in cortical circuits reveal that cellular diversity and temporal dynamics coemerged during evolution, providing a basis for cognitive behavior.read more

The origin of extracellular fields and currents — EEG, ECoG, LFP and spikes
TL;DR: High-density recordings of field activity in animals and subdural grid recordings in humans can provide insight into the cooperative behaviour of neurons, their average synaptic input and their spiking output, and can increase the understanding of how these processes contribute to the extracellular signal.

TL;DR: Large-scale single-cell RNA sequencing is used to classify cells in the mouse somatosensory cortex and hippocampal CA1 region and found 47 molecularly distinct subclasses, comprising all known major cell types in the cortex.

Mechanisms of Gamma Oscillations
György Buzsáki,Xiao Jing Wang +1 more
TL;DR: The cellular and synaptic mechanisms underlying gamma oscillations are reviewed and empirical questions and controversial conceptual issues are outlined, finding that gamma-band rhythmogenesis is inextricably tied to perisomatic inhibition.

Neurophysiological and Computational Principles of Cortical Rhythms in Cognition
TL;DR: A plethora of studies will be reviewed on the involvement of long-distance neuronal coherence in cognitive functions such as multisensory integration, working memory, and selective attention, and implications of abnormal neural synchronization are discussed as they relate to mental disorders like schizophrenia and autism.

TL;DR: Using genetic engineering in mice, approximately 20 Cre and inducible CreER knockin driver lines that reliably target major classes and lineages of GABAergic neurons are generated, thereby enabling a systematic and comprehensive analysis from cell fate specification, migration, and connectivity, to their functions in network dynamics and behavior.

Place units in the hippocampus of the freely moving rat
TL;DR: The results suggest that place units were not responding to a simple sensory stimulus nor to a specific motor behavior, and are interpreted as strong support for the cognitive map theory of hippocampal function.

Invariant visual representation by single neurons in the human brain
TL;DR: A remarkable subset of MTL neurons are selectively activated by strikingly different pictures of given individuals, landmarks or objects and in some cases even by letter strings with their names, which suggest an invariant, sparse and explicit code, which might be important in the transformation of complex visual percepts into long-term and more abstract memories.

Reverse replay of behavioural sequences in hippocampal place cells during the awake state
TL;DR: It is reported that sequential replay occurs in the rat hippocampus during awake periods immediately after spatial experience, which has a unique form, in which recent episodes of spatial experience are replayed in a temporally reversed order.

TL;DR: It is reported that three distinct interneuron types—basket, axo-axonic and oriens–lacunosum-moleculare cells—visualized and defined by synaptic connectivity as well as by neurochemical markers, contribute differentially to theta and ripple oscillations in anaesthetized rats.

Presynaptically Located CB1 Cannabinoid Receptors Regulate GABA Release from Axon Terminals of Specific Hippocampal Interneurons

TL;DR: The results suggest that cannabinoid-mediated modulation of hippocampal interneuron networks operate largely via presynaptic receptors on CCK-immunoreactive basket cell terminals, the likely mechanism by which both endogenous and exogenous CB1 ligands interfere with hippocampal network oscillations and associated cognitive functions.
