The effects of transcranial magnetic pulse stimuli on the brain tissue of rats were examined. In Experiment I, 52 male albino rats received pulsed magnetic stimulation of the head. Stimulus intensity, number of stimulations, stimulated sites, and interval between last stimulation and sacrifice for neuropathological examination were varied. High stimulus… (More)
The waveform and topography of components of the scalp recorded somatosensory evoked poal (AEP) to click stimulation of the right ear, were determined for scalp electrode locations of the 10-20 system and for locations at the eye, mastoids, and posterior neck. Twenty-one SEP and twenty-two AEP components were analyzed. Differentiation of neurogenic and… (More)
Rats were allowed to drink distinctively flavored water and later received an IP injection of LiCl. In Phase I, between drinking and the onset of the mild malaise, Experimental Group rats received stimulations of the head and Controls received equivalent stimulations of the back. Later, when the flavor was again presented. Experimentals drank 10-15% more,… (More)
Wave form differences were found in visual evoked response between normal and reading disabled children. These differences were maximally seen over the left parietal area but were minimal at the vertex and over the occipital area.
Visual evoked potentials elicited by strobe flash (fVEPs) were recorded in 56 infants (3 months to 15 months of age) with visual inattentiveness but without prechiasmal problems. Their visual status was reexamined one or more years later when 41 children were found to be visually competent (Group NB) and 15 were blind (Group B). We also evaluated a group of… (More)
In the latent pro-form of matrix metalloproteinase 7 (MMP-7), the cysteine residue in the pro-peptide binds the active-site zinc ion. Hence, recombinant active MMP-7 was prepared from pro-MMP-7 by modification of this cysteine residue with a mercuric reagent. In this study, mature MMP-7 was expressed in Escherichia coli as inclusion bodies, solubilized, and… (More)
