[Conditioning system for training cats to execute a typical prehension movement]. / Sistema per il condizionamento del gatto alla esecuzione di un tipico movimento di prensione.

This report describes a conditioning system for training cats to carry-out typical prehension's movements which exhibit the highest degree of reproducibility. It is composed of the following: a) a cage which is furnished with a particular foot-board to check the starting position of the front legs; b) an electropneumatic machine for transporting a bit of food; c) an electronic device for controlling and randomizing the time of nourishment.

[Electronic circuit for the control of current intensity of stimulating impulses at high isolation]. / Circuito elettronico per il controllo della intensita' di corrente di impulsi stimolanti ad elevato isolamento.

A small electronic apparatus is described, in which the pulses of current can be regulated from 0 at 10 mA. This apparatus permits the utilization of conventional tension stimulators.

[Semiautomatic regulator for the preparation of microelectrodes for electrophysiology]. / Dispositivo semiautomatico per la preparazione di microelettrodi per elettrofisiologia.

This paper describes an electronic device for making metallic microelectrodes to be used for electrophysiological experiments. These microelectrodes are endowed with a small tissue-electrode capacity and a high mechanical strength. The same microelectrodes are applicable for derivation of spikes as in the case of microstimulation of nervous structures during repeated penetrations.
