A pas de deux between the hippocampus and the cortex during sleep
In this Journal Club, Adrien Peyrache highlights a 1998 paper that showed memory formation as a dynamic process involving multiple brain areas.

Open AccessLocal origin of excitatory–inhibitory tuning equivalence in a cortical network
The interplay between excitation and inhibition determines the fidelity of cortical representations. The receptive fields of excitatory neurons are often finely tuned to encoded features, but the principles go...

Open AccessFlexible cue anchoring strategies enable stable head direction coding in both sighted and blind animals
Vision plays a crucial role in instructing the brain’s spatial navigation systems. However, little is known about how vision loss affects the neuronal encoding of spatial information. Here, recording from head...

Open AccessPrecise coupling of the thalamic head-direction system to hippocampal ripples
The anterior thalamus is a key relay of neuronal signals within the limbic system. During sleep, the occurrence of hippocampal sharp wave-ripples (SWRs), believed to mediate consolidation of explicit memories,...

Open AccessIntegrated open-source software for multiscale electrophysiology
The methods for electrophysiology in neuroscience have evolved tremendously over the recent years with a growing emphasis on dense-array signal recordings. Such increased complexity and augmented wealth in the...

The intrinsic attractor manifold and population dynamics of a canonical cognitive circuit across waking and sleep
Neural circuits construct distributed representations of key variables—external stimuli or internal constructs of quantities relevant for survival, such as an estimate of one’s location in the world—as vectors...

Open AccessAn ensemble code in medial prefrontal cortex links prior events to outcomes during learning
The prefrontal cortex is implicated in learning the rules of an environment through trial and error. But it is unclear how such learning is related to the prefrontal cortex’s role in short-term memory. Here we...

Open AccessTransformation of the head-direction signal into a spatial code
Animals integrate multiple sensory inputs to successfully navigate in their environments. Head direction (HD), boundary vector, grid and place cells in the entorhinal-hippocampal network form the brain’s navig...

Open AccessDynamic Balance of Excitation and Inhibition in Human and Monkey Neocortex
Balance of excitation and inhibition is a fundamental feature of in vivo network activity and is important for its computations. However, its presence in the neocortex of higher mammals is not well established. W...

Internally organized mechanisms of the head direction sense
Recording from population of head-direction cells across brain states, the authors provide experimental demonstration of the existence of internally organized attractor: the sequential activity of head directi...

Open AccessPrincipal component analysis of ensemble recordings reveals cell assemblies at high temporal resolution
Simultaneous recordings of many single neurons reveals unique insights into network processing spanning the timescale from single spikes to global oscillations. Neurons dynamically self-organize in subgroups o...

Replay of rule-learning related neural patterns in the prefrontal cortex during sleep
During sleep, neural patterns reflecting previously acquired information are replayed in the hippocampus. Here, the authors report that there is reactivation of learning-related patterns of activity in the med...

Neural Ensembles and Local Field Potentials in the Hippocampal-Prefrontal Cortex System During Spatial Learning and Strategy Shifts in Rats
To better understand the mechanisms of hippocampal-cortical signalling for mnemonic function and behavior, we recorded ventral hippocampal local field potentials (LFPs) simultaneously with ensemble neural acti...
