Sensory receptors encode stimuli by transiently synchronizing ongoing electrical oscillations, conferring enhanced sensitivity to communication signals produced by large groups of conspecifics.
Behavioral and neurophysiological recordings in infant rats reveal that sleep and sensory experience influence neural activity in prefrontal cortex, mirroring similar findings in developing sensorimotor cortex.
Dopaminergic medication has differential effects on the discovered electrophysiological networks, which could be used to develop new electrical and pharmacological interventions in Parkinson’s disease.

While perceptual content is encoded in non-oscillatory activity in the slow cortical potential (<5 Hz) range, perceptual stability is predominantly influenced by the amplitude fluctuations of alpha (~10 Hz) and beta (~20 Hz) brain oscillations.

Neurons can synchronize, supporting flexible communication among brain areas; closed-loop optogenetics allows the frequency and power of population oscillations to be dissociated, providing a tool to interrogate how networks couple.
Oscillation component analysis enables cognitive neuroscientists to summarize millisecond-precision high-dimensional neurophysiological recordings into a smaller set of oscillatory components through biophysically inspired generative modeling of neural oscillations.
Building on previous work (Baker et al., 2015), further evidence is reported for a novel mechanism for sensory coding based on the detection of oscillatory synchrony among peripheral receptors.

Neural spiking throughout the MTL is synchronous with hippocampal theta phase during spatial memory and navigation experiments in humans, even after controlling for phase-coupling to local theta oscillations.

Fungal hyphae constantly undergo signal oscillations, comparable to a cell 'monologue' until they meet another hypha with which they then coordinate signal oscillations and transit into a cell-to-cell dialogue.
