摘要： In one example, a system electrically stimulates target cells of a living animal using an elongated structure, a modulation circuit and a light pathway such as provided by an optical fiber arrangement. The elongated structure is for insertion into a narrow passageway in the animal such that an end of the elongated structure is sufficiently near the target cells to deliver stimulation thereto. The modulation circuit is for modulating the target cells while the elongated structure is in the narrow passageway, where the modulation circuit is adapted to deliver viral vectors through the elongated structure for expressing light responsive proteins in the target cells. The light pathway is used for stimulating the target cells by delivering light to the light-responsive proteins in the target cells.

摘要： According to one aspect and example, a method for facilitating cellular interactions in biological tissue provides controllable activation of a selected type of stem cell among a plurality of cell types present in the tissue. The method includes various steps including the introduction of a microbial opsin into a region of the tissue that includes a selected type of stem cell, by expressing the microbial opsin in the stem cell. A light source is then introduced near the stem cell, and the light source is used to controllably activate the light source to direct pulses of illumination from the light source to the selected type of stem cell, for selectively controlling the growth and development of the stem cell in a manner that is independent of the growth and development of the other types of cells.

摘要： Stimulation of target cells using light, e.g., in vivo, is implemented using a variety of methods and devices. In one such device, target cells are stimulated using an implantable device. The device includes a light source for producing light from electrical power. An optical transmission element is made from a material that is substantially transparent to the light from the light source. This transmission element substantially encases the light source at a proximal end. The transmission element delivers light from the light source to a distal end. The shape and size of the transmission element facilitates implanting of the element within a patient. A fixation portion physically couples to the optical transmission element and secures the device to the patient. A heat dissipation portion removes heat from the near optical transmission element and the light source and dissipates the removed heat through the fixation portion.

摘要： Various systems and methods are implemented for in vivo use in a living animal. One such method involves stimulating target cells having light-responsive proteins and includes providing an elongated light-delivery structure in a narrow passageway in the animal, the elongated light-delivery structure having separately-activatable light sources located along the length of the elongated light-delivery structure. The method also includes activating less than all the light sources to deliver light to light-responsive proteins adjacent to the activated light sources along the length of the elongated light-delivery structure, thereby stimulating target cells in vivo.

摘要： One embodiment involves modifying neural transmission patterns between neural structures and/or neural regions in a noninvasive manner. In a related exemplary method, sound waves are directed toward a first targeted neural structure and characteristics of the sound waves are controlled at the first target neural structure with respect to characteristics of sound waves at the second target neural structure. In response, neural transmission patterns modified to produce the intended effect (e.g., long-term potentiation and long-term depression of the neural transmission patterns). In a related embodiment, a transducer produces the sound for stimulating the first neural structure and the second neural structure, and an electronically-based control circuit is used to control characteristics of the sound waves as described above to modify the neural transmission patterns between the first and second neural structures.
