Induced movement in a patient is detected and correlated with a TMS stimulating pulse so as to determine the patient's motor threshold stimulation level. Direct visual or audible feedback is provided to the operator indicating that a valid stimulation has occurred so that the operator may adjust the stimulation accordingly. A search algorithm may be used to direct a convergence to the motor threshold stimulation level with or without operator intervention. A motion detector is used or, alternatively, the motion detector is replaced with a direct motor evoked potential (MEP) measurement device that measures induced neurological voltage and correlates the measured neurological change to the TMS stimulus. Other signals indicative of motor threshold may be detected and correlated to the TMS stimulus pulses. For example, left / right asymmetry changes in a narrow subset of EEG leads placed on the forehead of the patient or fast autonomic responses, such as skin conductivity, modulation of respiration, reflex responses, and the like, may be detected. The appropriate stimulation level for TMS studies are also determined using techniques other than motor cortex motor threshold methods. For example, a localized ultrasound probe may be used to determine the depth of cortical tissue at the treatment site. When considered along with neuronal excitability, the stimulation level for treatment may be determined. Alternatively, a localized impedance probe or coil and detection circuit whose Q factor changes with tissue loading may be used to detect cortical depth.

A protocol for use of growth factors to stimulate neuronal cell growth and activity in trkB receptor containing cortical tissues, including the entorhinal and hippocampal cortices. The method introduces exogenous growth factor, such as BDNF, NT-4 / 5 and NT-3, into the EC. The method is useful in therapy of defective, diseased and damaged neurons in the mammalian brain, of particular usefulness for treatment of neurodegenerative conditions such as Alzheimer's disease or for normal aging.

This procedure consists in the first stage, of the administration of enough quantity of bisphosphonate preparation during the necessary period of time to acquire a degree of volumetric mineral density of the cortical tissue of application, within the normal range (average.±.1 DS). Then the administration of the bisphosphonate preparation is interrupted in order to enable the development of the sectional momentum of inertia. The length of the second stage can be determined by means of a tomography. That is to say, that the periods of administration or non-administration of the mineralizing agent are defined or controlled by precise osteologic variables and therefore are not fixed. If during the second stage the cortical mineral density drops by 6-10% of the maximum value previously obtained, administration of bishphosphonate preparation should be resumed until the corresponding maximum adjusted value is reached again. The proposed procedure of a period with bisphosphonate followed by another period without the bisphosphonate agent improves fracture resistance, provided that the length of both periods is controlled by defined osteologic variables.

The invention discloses an externally-used medicine for recovering a burned cortical tissue and a preparation method thereof. The externally-used medicine is prepared from the following raw materials in parts by weight: 3-8 parts of elephant skin, 10-15 parts of sulfur, 15-20 parts of sodium borate, 1-3 parts of borneol, 1-3 parts of musk, 20-30 parts of calamine, 20-30 parts of gypsum and 100-120 parts of sesame oil. The preparation method comprises the following steps: (1) putting the sulfur, the elephant skin, the sodium borate, the borneol, the calamine and the gypsum into a marmite, sealing the marmite by a porcelain bowl and totally sealing the joint of the porcelain bowl and the marmite with mud; (2) heating for half an hour by strong fire, subsequently heating for two hours by soft fire and cooling to room temperature; (3) opening the marmite, removing the medicine attached to the porcelain bowl, adding musk, uniformly mixing, grinding into powder and sieving by a sieve of which the size is 100 meshes to obtain medicine powder; (4) mixing the obtained medicine powder with the sesame oil according to a ratio of 1:20 to obtain an oily externally-used medicine for recovering the burned cortical tissue. The externally-used medicine disclosed by the invention has the advantages of being rapid in healing, good in treatment effect, capable of being used for recovering the burned cortical tissue and the like.
