A general theory of neural circuitry is proposed wherein neural impulses travel in a continuous circuit from the brain to the extremities and back to the brain. At the extremities the impulse may be modified by the environment there. At the spinal column the return signal is compared with the outgoing signal and the appropriate motoneuronal 'reflex' signal(More)
We discuss the method of field strength calibration from energy distributions measurements of free space field ionization. An alternative approach is considered and an improved calibration is suggested. The method of electric field strength calibration from considerations of energy distribution of field ionization in free space above a field ion emitter tip(More)
The Field Ion Microscope image quality is dependent on operational ? which can be adjusted in order to improve resolution and contrast, he best image operation conditions are discussed with the aim to define them quantitatively. To do so, a JWKB calculation for the ionization distribution is used and a new interpretation of the best image conditions is(More)
