Independent coding without synaptic coordination explains complex sequences of population activity observed during theta states and maximizes the number of distinct environments that can be encoded through population theta sequences.
Phase-locking of hippocampal theta and gamma waves has been proposed to support memory formation, but an analysis using robust statistical methods finds no convincing evidence for the phenomenon.
A computational framework and analysis of rodent CA1 data reveals that theta oscillations sequentially sweep through the past, present, and future at a spatial scale that varies with the characteristic speed of the animal.
A combination of signal processing and machine learning form a new approach to classify oscillatory coupling in single cycles without averaging over time and to capture cycle-by-cycle changes in coupling.

Techniques are presented to facilitate widespread and standardized chronic use of Neuropixels probes for high-yield, long-term neural recording in freely moving animals.
Interrogating mouse locus coeruleus via large-scale multipatch whole-cell recordings uncovers its cellular heterogeneity and cell-type-specific wiring logic.
A spatially-tuned normalization model accounts for neuronal responses to attended or unattended stimuli that are presented inside the classical receptive field or the surround, and explains various other observations.
