Multiple single-unit recording has become one of the most powerful in vivo electro-physiological techniques for studying neural circuits. The demand has been increasing for small and lightweight chronic recording devices that allow fine adjustments to be made over large numbers of electrodes across multiple brain regions. To achieve this, we developed precision motorized microdrive arrays that ...

Traditional multibarreled pipette electrodes are still widely used in microiontophoresis studies. Although better electrodes have been introduced, they are difficult and time-consuming to make. Construction of a carbon fiber recording and microiontophoresis assembly is described here. The construction of a carbon fiber electrode assembly is easy and carbon fibers have excellent characteristics ...

Abstract The Swift Terrestrial Passive Acoustic Recording Unit from Cornell Lab of Ornithology, running firmware v. STM32 0.18.6.3, produced an initial 4‐sec sound anomaly in each (wave file) recording, created by the power‐saving features unit as it switches standby to record mode. had a statistically significant impact on several soundscape indices calculated recordings. Here, case study iden...

Recording simultaneous activity of a large number of neurons in distributed neuronal networks is crucial to understand higher order brain functions. We demonstrate the in vivo performance of a recently developed electrophysiological recording system comprising a two-dimensional, multi-shank, high-density silicon probe with integrated complementary metal-oxide semiconductor electronics. The syst...

OBJECTIVE To analyze the process of recording transfusion monitoring at a public teaching hospital. METHODS A descriptive and retrospective study with a quantitative approach, analyzing the instruments to record transfusion monitoring at a public hospital in a city in the State of Minas Gerais (MG). Data were collected on the correct completion of the instrument, time elapsed from transfusion...

By simultaneous recording from neural responses at many different loci at the same time, we can understand the interaction between neurons, and thereby gain insight into the network properties of neural processing, instead of the functioning of individual neurons. Here we will discuss a method for recording in behaving animals that uses chronically implanted micro-electrodes that allow one to t...

We studied the usefulness of an MR imaging-compatible electroencephalography (EEG) electrode system for continuous EEG recordings in our epilepsy monitoring unit (EMU) by comparing 100 consecutive patients with MR imaging-compatible and MR imaging-incompatible EEG recording electrodes who underwent MR imaging between 3:00 pm and 7:00 am. The MR imaging-compatible system captured seizures in 21/...

The architecture of the device recording randomly occurring events has been described in the present study. A/m device has been designed and built in order to enable the recording of broad – band acoustic emission signal (AE). The system of the recorder has been configured in the manner enabling its operation in the autonomous unit operation mode or its application as IBM PC extension card. The...
