Very fast oscillations (VFOs; 500-1,500 Hz) are associated with sensory-evoked potentials (SEPs), but their origin is unknown. To characterize the origins of VFOs, we studied 35 patients with deep brain stimulation (DBS) electrodes [15 with thalamic and 20 with the subthalamic nucleus (STN) electrodes]. We recorded median nerve stimulation-evoked SEPs from the thalamus and STN with microelectrodes during stereotactic surgery and from the contacts of the DBS electrodes postoperatively. We also…

Somatosensory evoked potentials recorded from the human pedunculopontine nucleus region

The results suggest that there are direct somatosensory inputs to the PPNR, and the slow components and HFOs of the SEP have different origins.

High-Frequency Oscillations in Somatosensory System

High-frequency oscillation has been studied in several ways: their modulation by arousal changes, movements or drugs, their recovery function, effects of transcranial magnetic stimulation on them and also their changes in patients with various neurological diseases.

Thalamo‐cortical processing of near‐threshold somatosensory stimuli in humans

The results indicate that the thalamus remains active after the primary propagation of a sensory signal to the cortex, and suggest that the transition from elementary to higher‐order somatosensory processing is based on thalamo‐cortical interactions.

Intracellular correlates of fast (>200 Hz) electrical oscillations in rat somatosensory cortex.

It is proposed that fast oscillations define preferred latencies for action potential generation in cortical RS cells, with VFO generated by inhibitory interneurons and FO reflecting both sequential and recurrent activity of stations in the cortical lamina.

Synchronized spikes of thalamocortical axonal terminals and cortical neurons are detectable outside the pig brain with MEG.

It is shown that it is feasible to monitor the synchronized population spikes of the thalamocortical axonal terminals and cortical neurons outside the brain using high-resolution magnetoencephalography (MEG), and the results suggest that it may be possible to study properties of theThalamoc Cortical and cortical spike activities in humans with MEG.

Spatiotemporal characteristics of human intrathalamic high-frequency (>400Hz) SEP components.

High-frequency thalamic SEP bursts probably reflect a superposition of slightly asynchronously triggered population spikes, generated e.g. by bursting thalamocortical relay cells.

Neurophysiological identification of the subthalamic nucleus in surgery for Parkinson's disease

These findings suggest that STN neuronal activity is elevated in Parkinson's disease, and electrical microstimulation of STN could produce tremor arrest but were and found to be useful for localization.

A gamma-aminobutyric acid inhibitory interneuron hypothesis is presented based primarily on the findings regarding reciprocal modulation of the high-frequency oscillations and the underlying magnetic N20 (N20m) by a wake-sleep cycle and by attention or interference.
