Abstract: A system for anchoring a lead within a cranial burr hole. The system provides for a lead to be anchored in either of two sizes of burr holes. In further provides for the lead to remain secured to the stereotactic instrument during the installation of the lead anchoring system. The lead anchoring system consists of three parts: A plug having a central lead passage; a cap configured to fit over the plug while the lead is retained by the stereotactic instrument and thereby seal the burr hole and anchor the lead; and a socket designed to permit the plug to be fitted within a larger sized burr hole. In the preferred embodiment each of the parts, i.e. plug, socket and cap are constructed from silicone. The anchoring system of the present invention may be employed with a stimulation lead, a sensing lead, a combination thereof or any other elongated member requiring passage and fixation through the cranium.

Abstract: A method and apparatus for multifaceted electroencephalographic response analysis (MERA) is described. MERA involves presenting stimuli to a subject through at least one of the visual and auditory modalities, recording electrophysiological brain responses indicative of information processing in response to said stimuli, and analyzing multiple features of said brain responses. This technique is used both to detect concealed information in the brain and to communicate directly from a brain to a computer, and thus to command computers and also to command mechanical devices.

Abstract: An improved method and apparatus for stimulating the growth and healing of living, especially human, tissues, promoting the healing of wounds and skeletal fractures. An electrical apparatus consists of a baseplate, made of lightweight nonconductive material, for encompassing all or a portion of a body member. A multiplicity of generally evenly spaced holes are provided in the baseplate and a probe adapter including a moveable electrically conductive probe is situated within the holes, as desired. An electric contact connects the interior of each adapter and the probe situated therein to a terminal on the baseplate. Each probe is individually adjustable to contact the wearer's body part within the base member regardless configuration of the body part, thus allowing treatment of all or a selected portion of the body part.

Abstract: Hair regrowth is promoted by positioning one or more electrodes closely proximate a subject's scalp. A low voltage positive or negative polarity signal having a selected frequency of either 7.86 or 15.72 hertz is applied to the electrode(s) for about twelve minutes. The subject undergoes a hair regrowth treatment cycle spanning a period of about thirty-two weeks during which one or two of the treatments aforesaid are applied per week.

Abstract: An electrode for providing TCET, especially via the earlobes of the patient, comprises an electrical conductor for application to the skin, connected to a lead for supplying the TCET signal from a signal generating device, characterized in that the conductor comprises a generally conical needle point capable of penetrating the epidermis so as to provide good electrical contact over a very small area. The electrode can be used in the impedance of less than 100 k.OMEGA.; and with apparatus for generating an electrical signal for use in TCET, adapted to provide a signal at a current of less than 200 .mu.A (0.2 mA), especially when adapted to provide an AC signal in which each positive pulse is relatively short and high without being spiked and the following negative pulse is relatively wide and low, the total amount of positive and negative charge being balanced. Methods of providing TCET treatment to patients using the electrode and apparatus are also provided.
