A manual counter for recording multiple behavior1

A reliable wrist counter for recording behavior rates.

Over the past three years, a wrist-type golf-score counter has been found helpful in recording movement rates for behavior modification and analysis. Several different types are available from local sporting goods stores. The most cosmetic and reliable model located to date is the "Domatic Score", which is manufactured in Switzerland and can be obtained from the Hoffritz Cutlery Company, 49 Eas...

A Sub-µW Tuneable Switched-Capacitor Amplifier-Filter for Neural Recording Using a Class-C Inverter

A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...

A new method for acquisition and analysis of single unit recording data

Single unit recording has been used as a well-known technique to study the electrical behavior of neurons. In this respect, the classical methods are rather expensive. In this study a simple and inexpensive method for single unit recording studies has been introduced. Computer sound card was used for data acquisition. Neural responses were saved via simple sound applicable packages and then ana...
