    摘要: Optical methods, devices, and systems for non-invasively detecting transient surface displacements in a neuron are disclosed. Methods, devices, and systems provided may employ a phase-sensitive optical low coherence reflectometer. In addition, surface displacements due to action potential propagation in neural tissues may be detected in some embodiments using back-reflected light. According to some embodiments, exogenous chemicals or reflection coatings are not required. Transient neural surface displacement of less than 1 nm in amplitude and 1 ms in duration may be detected and may be generally coincident with action potential arrival to the optical measurement site. The systems and methods may be used for noninvasive detection of various neuropathies such as retinal neuropathies. They may also be useful in detecting the effects of various pharmacological agents.

    摘要: Intracranial pressure transducer System, wherein a holding bracket containing and supporting sensor elements of the apparatus is surgically positioned, through an opening in the skull, against the dura of a neurosurgical patient. The elements within the holding bracket transmit signals in the form of radiated electromagnetic waves to a receiver located outside the body of the patient. The received signals may be recorded on magnetic tape, may be converted to audible sounds, and/or may be recorded on charts, or otherwise suitably preserved and/or presented for use in monitoring the intracranial pressure of the patient.
