Stereotaxic Techniques
Abstract
In order to unravel the mechanisms underlying the "sudden" onset of spontaneous absences in genetically prone subjects, we investigated the immediate precursors of spike-wave discharges (SWDs) produced in cortico-thalamo-cortical neuronal networks.

Abstract
We reported smaller volume and width of the outer cortex (layers I-III), especially in the left hemisphere, among subjects with schizophrenia. In the present study, we measured neuron density and size in the same PT samples, and also in prefrontal area 9 of the same brains. In the PT, separate stere...

Abstract
We injected micron-sized silver particles into the mouse brain by stereotactic procedures. After 7 days, 14 days and 9 months, the silver-exposed animals had considerable brain damage seen as cavity formation and inflammation adjacent to the injected metallic silver particles. The tissue loss involv...

Abstract
Erythropoietin (EPO) is a potent neuroprotective agent that could be developed as a new treatment for stroke. However, the blood-brain barrier (BBB) is intact in the early hours after stroke when neuroprotection is still possible, and EPO does not cross the intact BBB. To enable BBB transport, human...

Abstract
The inability of axons in central nervous system (CNS) to regenerate after injury is related partly to multiple endogenous axon growth inhibitors including Nogo receptor (NgR). This study tested the hypothesis that silencing NgR expression by adenovirus-mediated RNA interference (RNAi) (AD-NgR) may...

Abstract
We have previously shown that deficits in vocal learning occur in zebra finches after reduction of FoxP2 in Area X, a striatal nucleus involved in song acquisition. We recently showed that FoxP2 is expressed in newly generated spiny neurons (SN) in adult Area X as well as in the ventricular zone (VZ...

Abstract
Radiation therapy is commonly used in the treatment of cancer. The normal tissue tolerance can be a limit to deliver enough dose to the tumor to be curative. The synchrotron beam presents some interesting physical properties, which could decrease this limitation. Synchrotron beam is a medium energy...
