Recent evidence shows that spatial attention is discontinuous over time, sampling locations in rhythmic cycles (3–6 Hz). Here, the authors show that the pulvinar has a role in coordinating this rhythmic sampling, with neural activity propagating from pulvinar to cortex during periods of engagement.

Memories formed around the same time are linked together by a shared temporal context. Here, the authors show that the ability to selectively retrieve distinct episodic memories formed close together in time is related to how quickly neural representations of temporal context change over time during encoding.

Arrays of graphene microtransistors are used to record infraslow cortical brain activity. The reduced signal drift and the array compatibility with optical imaging techniques make these devices useful for monitoring of brain physiology.

A closed-loop and wireless 128-channel neuromodulation device enables electrical stimulation as well as artefact-free long-term recording of local field potentials in the brain of an untethered non-human primate.

Peripheral nerves have a complex physiology and it is therefore difficult to measure axonal activity in vitro. Here the authors make a nerve-on-a-chip platform to align peripheral nerves and permit measurement of conduction amplitude and velocity along several axons in a single experiment.

Implantable inductively coupled resonant circuits that change their properties in response to electrical or photonic cues and are detectable in magnetic resonance imaging enable the remote sensing of bioluminescence in rodent brains.
