Stimulation within the cuneate nucleus suppresses synaptic activation of climbing fibers

Frontiers in Neural Circuits, 2013
Several lines of research have shown that the excitability of the inferior olive is suppressed during different phases of movement. A number of different structures like the cerebral cortex, the red nucleus and the cerebellum have been suggested as ...

Optical colours of AGN in the Extended Chandra Deep Field South: Obscured black holes in early type galaxies

, 2007
We investigate the optical colours of X-ray sources from the Extended Chandra Deep Field South (ECDFS) using photometry from the COMBO-17 survey, aiming to explore AGN - galaxy feedback models.

Evidence of Fragmenting Dust Particles from Near-Simultaneous Optical and Near-IR Photometry and Polarimetry of Comet 73P/Schwassmann-Wachmann 3 [PDF]

, 2008
We report imaging polarimetry of segments B and C of the Jupiter-family Comet 73P/Schwassmann-Wachmann 3 in the I and H bandpasses at solar phase angles of approximately 35 and 85deg.

Evaluation of iron deposition in brain basal ganglia of patients with Parkinson's disease using quantitative susceptibility mapping

European Journal of Radiology Open, 2019
Aim of the study: Parkinson's disease is associated with iron deposition in the brain. The QSM (quantitative susceptibility mapping) is more sensitive than T2-weighted imaging, T2* and R2.

Detailed abundances of a large sample of giant stars in M 54 and in the Sagittarius nucleus

, 2010
Homogeneous abundances of light elements, alpha and Fe-group elements from high-resolution FLAMES spectra are presented for 76 red giant stars in M54, a massive globular cluster (GC) lying in the nucleus of the Sagittarius dwarf galaxy.

Stellar production rates of carbon and its abundance in the universe [PDF]

, 2000
The bulk of the carbon in our universe is produced in the triple-alpha process in helium-burning red giant stars. We calculated the change of the triple-alpha reaction rate in a microscopic 12-nucleon model of the C-12 nucleus and looked for the effects ...

Excitatory rubral cells encode the acquisition of novel complex motor tasks

Nature Communications, 2019
The red nucleus (RN) is a midbrain nucleus known to be involved in the fine control of limb movements, but its role in motor learning is unclear. Here, the authors identified a neuronal population within the red nucleus, co-expressing Vglut2, PV and ...

The diversity and plasticity of descending motor pathways rewired after stroke and trauma in rodents

Frontiers in Neural Circuits
Descending neural pathways to the spinal cord plays vital roles in motor control. They are often damaged by brain injuries such as stroke and trauma, which lead to severe motor impairments.

Hypertrophic degeneration of the inferior olivary nucleus impacts perception of gravity

Frontiers in Neurology, 2012
Interruption of the Guillain-Mollaret triangle interconnecting the red nucleus, the inferior olivary nucleus and the contralateral dentate nucleus is predicted to interfere with the dentate nucleus’ role in estimating direction of gravity.
