a command
and the computer immediately responds. “Thought recognition
would be the ultimate computer interface, the machine acting as
an extension of the human nervous system itself.”(Lusted, Hugh S.
and Knapp, R. Benjamin Controlling Computers with Neural Signals
Scientific American, October 1996) This technology would prove
very useful for people with neuromuscular handicaps. The purpose
of this paper is to show how controlling computers with neural
signals will help make life easier for people with handicaps and
how it will affect the future.
Computer technology has advanced considerably in the
last forty years. Even with all these advances, constructing a
versatile neural junction between a human brain and an electronic
one remains a formidable challenge.(Lusted, Hugh S. and Knapp, R.

He made these observations using a primitive device for measuring
voltages called a galvanometer.
Galvanometers are used with direct current are most commonly of
the D’Arsonval type. A small coil of fine wire held by two
springs is pivoted between a pole of a permanent magnate. The
current moving through the wire causes the coil to develop a
magnetic field of its own, which makes it rotate with respect to
the magnate. (Galvanometer ...
