We present for the first time direct electrophysiological evidence of the phenomenon of traveling electrical waves produced by populations of interneurons within the spinal cord. We show that, during a fictive rhythmic motor task, scratching, an electrical field potential of spinal interneurons takes the shape of a sinuous wave, "sweeping" the lumbosacral(More)
For the first time, here we characterize a bulbar reticular activating system (RAS) of neurons in decerebrate, deafferented and decerebellated cats producing a premovement electrical potential that we named obex slow potential (OSP). The OSP occurs about 0.8 ± 0.4 sec prior to the onset of a fictive-scratching-episode. Here, we describe two classes of(More)
The neonatal ventral hippocampal lesion (NVHL) is an established neurodevelopmental rat model of schizophrenia. Rats with NVHL exhibit several behavioral, molecular and physiological abnormalities that are similar to those found in schizophrenics. Schizophrenia is a severe psychiatric illness characterized by profound disturbances of mental functions(More)
Magic syndrome is a very uncommon disease, and vascular involvement is exceptional; only one case has been reported in the literature associated to a true aortic aneurysm. The treatment of aneurysms recommended in these patients is based on isolated cases and includes corticosteroids, other immunosuppressant drugs, and surgery. We report a case of a patient(More)
Each year, 182,000 women are diagnosed with breast cancer and 43,300 die, only in America. Currently, more than a million of new cases will be detected around the world. One woman in eight either has or will develop breast cancer in her lifetime. Mammograms are among the best early detection methods. Most women with breast cancer have some type of surgery:(More)
Spontaneous cord dorsum potentials (spontaneous CDPs) are produced by the activation of dorsal horn neurons distributed along the L4 to S1 spinal cord segments, in Rexed's laminae III-VI, in the same region in which there are interneurons rhythmically bursting during fictive scratching in cats. An interesting observation is that spontaneous CDPs are not(More)
