Spontaneous brain oscillations and perceptual decision-making
Making rapid decisions on the basis of sensory information is essential to everyday
behaviors. Why, then, are perceptual decisions so variable despite unchanging inputs …

Neural effects of propofol-induced unconsciousness and its reversal using thalamic stimulation
The specific circuit mechanisms through which anesthetics induce unconsciousness have
not been completely characterized. We recorded neural activity from the frontal, parietal, and …

A corticothalamic switch: controlling the thalamus with dynamic synapses
Corticothalamic neurons provide massive input to the thalamus. This top-down projection
may allow the cortex to regulate sensory processing by modulating the excitability of …

Multiple gamma rhythms carry distinct spatial frequency information in primary visual cortex
Gamma rhythms in many brain regions, including the primary visual cortex (V1), are thought
to play a role in information processing. Here, we report a surprising finding of 3 narrowband …

Transcranial ultrasound neuromodulation of the thalamic visual pathway in a large animal model and the dose-response relationship with MR-ARFI
Neuromodulation of deep brain structures via transcranial ultrasound stimulation (TUS) is a
promising, but still elusive approach to non-invasive treatment of brain disorders. The …

Corticofugal circuits: Communication lines from the cortex to the rest of the brain
Pyramidal cells in cortical Layers 5 and 6 are the only cells in the cerebral cortex with axons
that leave the cortex to influence the thalamus. Layer 6 cells provide modulatory feedback …

EEG oscillations entrain their phase to high-level features of speech sound
Phase entrainment of neural oscillations, the brain's adjustment to rhythmic stimulation, is a
central component in recent theories of speech comprehension: the alignment between …

Gamma rhythms in the visual cortex: functions and mechanisms
Gamma-band activity, peaking around 30–100 Hz in the local field potential's power
spectrum, has been found and intensively studied in many brain regions. Although gamma …
