An integrated circuit shock scrambler

A simple design of shock-scrambler unit for studies on foot-shock elicited aggression in rats.

A simplified circuit design for fabricating a shock scrambler unit (SSU) is described in this note. This instrument finds application in research studies on aggression behaviour using rats for the experiments. In this experimental production of aggression, an aversive mood is generated in pair of rats kept in a test chamber by giving electric foot-shocks to them, and this evokes the fighting be...

An Analog Integrated Circuit Design Laboratory

We present the structure of an analog integrated circuit design laboratory to instruct at both, senior undergraduate and entry graduate levels. The teaching material includes: a laboratory manual with analog circuit design theory, pre-laboratory exercises and circuit design specifications; a reference web page with step by step instructions and examples; the use of mathematical tools for automa...

An Approach to Integrated Numericaland Symbolic Circuit

An interface to symbolic circuit analysis has been developed for a SPICE{like circuit simulator in order to integrate numerical simulation with an existing program for symbolic circuit analysis. In eeect, both numerical and symbolic analyses use the same internal representation of circuits which makes the two approaches truly complementary. This integrated simulation capability is used in simul...

An Integrated Circuit for Tissue Impedance Measure

In this paper, the design of aa Integrated Circuit (IC) for the measurement of tissue impedance is presented. The chip is intended to be used in monitoring biomedical parameters in living bodies. Tissue impedance is one of these parameters which allows ischemia monitoring. The designed IC is used in a four-electrode based set-up in order to minimize the effect of electrode-electrolyte interface...
