• ### Implantable Blood Pressure Telemetry System

Publication Year: 1972, Page(s):334 - 341
Cited by:  Papers (9)
| |PDF (2159 KB)

A telemetry system for long-term monitoring of the blood pressure of unrestrained animals is described. The wholly implantable transmitter is equipped with a pressure transducer suitable for chronic intravascular use. To achieve high performance and long battery life, a greater number of components were used than in conventional implantable devices. Pulse interval modulation is used with a mean sa...

| |PDF (6452 KB)

A new solid-state device has been developed for the measurement of ion activities in electrochemical and biological environments. One can recognize in the device the properties of both a glass electrode and a field-effect transistor. This justifies the name ion-sensitive field-effect transistor. The device makes it possible to measure ion activities without using a reference electrode. For its app... View full abstract»

| |PDF (3001 KB)

A three-dimensional finite difference computer simulation has been used to model entire intracranial fields from a known dipole generator in both a cat brain and an insulated cube. The model permits pointwise variation of conductivity coincident with intracranial inhomogeneities due to gray and white matter, cerebrospinal fluid, and bone. Adequacy of the model was verified by agreement between the... View full abstract»

• ### A Theoretical Neural Integrator

Publication Year: 1972, Page(s):362 - 367
Cited by:  Papers (14)
| |PDF (1497 KB)

A neural network model is introduced which approximates the behavior of an integrator. It is developed from cells that are physiologically realistic. Requirements for insensitivity of network function to cell threshold distribution are derived, and network performance as the forward-path element of a neuromuscular control system is analyzed. The response of the integrator'' to sustained inputs i... View full abstract»

| |PDF (4009 KB)

The construction of a lightweight quadrifillar needle electrode offering four monopolar and six bipolar microelectrode combinations is described. The electrode has three useful features: 1) it can record distinct individual motor unit action potentials during strong muscle contractions, 2) the frequency response curve of the electrode can be altered to a simple functional relationship within the f...

| |PDF (1129 KB)

The importance of diffusion phenomena in glass micropipettes filled with concentrated electrolyte solutions is well known. Nonequilibrium diffusion-rate equations for electrolyte-filled glass micropipettes are given for a model of situations of current interest: diffusion into an infinite medium. The solutions of these equations give the flux of material out of a micropipette as a function of time... View full abstract»

| |PDF (6624 KB)

A dual-window video densitometer was developed for the measurement of dimensions of televised scenes. Filter and hold circuitry used to convert the output into analog signals proportional to the dimension being measured obviate the use of specialized computers. The system was utilized to study the change of dimension of the in vivo human heart. View full abstract»

| |PDF (3604 KB)

An attempt to quantitate the organization of the human uterus was made by measuring the maximum amplitude and the maximum and minimum slopes of the intrauterine pressure waveform prior to induced labor and during spontaneous and induced labors. No apparent differences in the ratio of the maximum amplitude to the maximum and minimum slopes were found in these three physiological states. All the cor... View full abstract»
