Enhancement of afferent fiber activity in hippocampal slices
(Elsevier, 1980-10-06)
The potentiation of synaptic activity in the hippocampal formation is a well documented phenomenon. It has been suggested, however, that a recruitment of additional afferent fibers can contribute to such an increase in ...
Field-potential evidence for extrasynaptic alterations in the hippocampal CA1 pyramidal cell population during paired-pulse potentiation
(Elsevier, 1983-04)
The mechanisms of paired-pulse potentiation of the CA1 pyramidal cell population were examined by determining input-output relations for control and potentiated responses originating from the activation of radiatum fibers ...
Self Assembly and Optical Properties of Dendrimer Nanocomposite Multilayers
(WILEY-VCH Verlag, 2007-08-07)
Ultrathin multilayers are important for electrical and optical devices, as well as for immunoassays, artificial organs, and for controlling surface properties. The construction of ultrathin multilayer films by electrostatic ...
Automated interpretation of cardiac arrhythmias : Design and evaluation of a computerized model
(Elsevier, 1993-01)
Historically, the development of computerized models that utilize the deductive methods used by clinicians for the interpretation of cardiac arrhythmias have been limited by the absence of a consistently reliable means of ...
Charge-density domains in photoexcited quantum-well structures
(Elsevier, 1990-04-01)
We present theoretical and experimental results on the dielectric response of an electron-hole plasma confined to a quantum-well. Hartree calculations reveal large nonlinearities in the screening properties which, when ...
Automatic computer processing of digital 2-dimensional echocardiograms
(Elsevier, 1983-08)
Quantitative studies of left ventricular function using 2-dimensional echocardiography have been limited because of a lack of computerized methods to automatically analyze the echocardiographic images. Previous computer ...
Single retinal ganglion cell responses in the dark-reared rat: Grating acuity, contrast sensitivity, and defocusing
(Elsevier, 1978)
The visual acuity, refractive state, and depth of focus of the dark-reared hooded rat's dark-adapted eye were determined by recording the responses of retinal ganglion cell axons in the optic tract. The smallest square-wave ...
