“…The realized system for the acquisition and archiving of brain cell signals has been developed on the following principle: the brain cell signals were locally digitalized [5] upon the head of the animal (Fig. 1.a); the multiplexed signal was wirelessly transmitted to the stationary unit of the system (Fig.…”

“…The sources of the signal are the brain cells of the experimental animal: mouse, rat, monkey, etc. The probes for collecting the data are of invasive type [5]. The measured signals are of low intensity, whose A/D conversion is done locally, upon the head of the animal, to weaken the annoying effect of noise [17].…”

“…-The first group consists of systems where only measurements are done upon the head of an animal (with or without digitalizing the signal, but without processing it) and data are transmitted real time to the stationary unit [5,6]. -The second group consists of systems, of which, in addition to performing measurements upon the head of an animal, locally extract useful information (they extract, for instance, information in reference to spikes, or do compression with a loss) which is sent to the stationary unit [7,8].…”

A central goal of systems neuroscience is to simultaneously measure the activities of all achievable neurons in the brain at millisecond resolution in freely moving animals. This paper describes a protocol converter which is part of a measurement acquisition system for multichannel real time recording of brain signals. In practice, in such techniques, a primary consideration of reliability leads to great necessity towards increasing the sampling rate of these signals while simultaneously increasing the resolution of A/D conversion to 24 bits or even to the unprecedented 32 bits per sample. In fact, this was the guiding principle for our team in the present study. By increasing the temporal and amplitude resolution, it is supposed that we get enabled to discover or recognize and identify new signal components which have previously been masked at a "low" temporal and amplitude resolution, and these new signal components, in the future, are likely to contribute to a deeper understanding of the workings of the brain.
