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.
Oscillations that co-occur in hippocampal CA1 during exploration in the rodent are shown to segregate according to exploratory and sleep states in the primate.
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.

Integration and segregation of information of memory and sensory in the hippocampus could be achieved by the coordination of distinct theta-gamma coding frameworks.

Driving theta–gamma activity in the human cortex with non-invasive brain stimulation enhances motor skill acquisition in healthy adults, revealing a potential neuroplastic mechanism that might be harnessed for therapeutic intervention.
Inhibitory noninvasive stimulation to the precuneus disrupts theta and gamma oscillatory coupling between medial temporal lobes and neocortical regions during complex personal memory retrieval.

Tetrode recordings show that the amplitude of gamma oscillations encodes for information on contextual odorant identity when observed at the peak phase of the theta oscillation in the olfactory bulb.

Building on previous work (Sweeney-Reed et al., 2014), it is shown that the timing of the theta rhythm of the right anterior thalamic nucleus predicts human memory formation.
