Claims19
A method for describing the distribution of neurons in living tissue without causing unpleasant stimulation, the method comprising:
- imposing a magnetic gradient on the tissue within a short transition time, and
- assessing the spatial distribution or orientation of previously introduced magnetizable particles with a spatial resolution better than 500 microns.
An apparatus configured to describe distribution of neurons in living tissue without causing unpleasant stimulation, the apparatus comprising:
- coils and drivers configured to impose a strong magnetic field on the tissue with a short transition time, and
- coils and drivers configured to assess the spatial distribution of previously introduced magnetizable particles with a spatial resolution better than 500 microns.
An apparatus configured to describe a function of neurons in living tissue without causing unpleasant stimulation, the apparatus comprising:
- coils and drivers configured to impose a strong magnetic gradient on the tissue with a short transition time, and
- previously introduced at least one particle containing magnetizable material, and in which the state of the particle depends on the function of nearby neurons, and
- coils and drivers configured to detect the state of such particles.
An apparatus configured to describe a function of neurons in living tissue without causing unpleasant stimulation, the apparatus comprising:
- coils and drivers capable of imposing a strong magnetic gradient on the tissue with a short transition time, and
- previously introduced at least one particle containing magnetizable material, and which particle can emit signals depending on the function of nearby neurons, and
- coils and drivers for detecting the signals emitted by such particle.
