The invention provides an evaluation method capable of objectively evaluating average visual perception for a comparatively long period of time when a subject looks through an eyeglass lens to be evaluated, time-dependent change in visual perception, and visual perception when looking with both eyes, and the invention provides a design method, and the invention provides a calculation method for calculating characteristics of visual perception of the subject when viewing an object through a lens. [Solution] A subject is allowed to wear a lens to be evaluated, the subject is allowed to induce brain activity by allowing the subject to view a changing visual stimulus object that induces periodic brain activity through the lens to be evaluated, a change in faint electric current caused by the brain activity is time-dependently recorded as a change in a magnetic field (magnetic flux density) by use of a magnetoencephalograph, one or more among an amplitude, a power value, and a phase in a frequency that is an inverse number of a period of the periodic brain activity is or are calculated through fast Fourier analysis of the waveform, and the lens to be evaluated and the characteristic of visual perception of the subject are evaluated based on a magnitude of an amplitude or of a power value obtained above or based on a slowness/fastness of a phase obtained above.

A magnetic resonance imaging apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to specify a search start position of a matrix representing inter-regional connectivity between a plurality of regions in a brain based on a result of an analysis on an image of a subject and an attention degree set to each of the regions. The processing circuitry is configured to search the matrix using the search start position.

A device for detection of the tactile sensitivity of a user includes a base frame and a mechanical system joined to the base frame, the mechanical system being movable relative to the base frame and having a resting area for the fingertip of at least one finger of the user. The mechanical system includes a plurality of movable plate-shaped members arranged side by side to each other so that the resting area is defined by the thicknesses of at least part of the upper edges of the plate-shaped members. Each plate-shaped member is connected to an actuator, which can be operated to independently move each plate-shaped member from a minimum height position to a maximum height position, a control unit being further provided, which is adapted to operate the actuators.

Apparatus for ophthalmic electrophysiological testing, the apparatus comprising: an EER stimulator for providing an electrical stimulus to an eye so as to evoke an electrophysiological response, wherein the EER stimulator comprises a power source; an amplifier for receiving the electrophysiological response and measuring that response, wherein the amplifier is integrated with the EER stimulator; and at least one switch disposed between the power source and the amplifier for isolating the power source from the amplifier when the electrical stimulus is delivered to the eye.

A method of assessing nerve conduction of a trigeminal nerve in a subject in response to an oral cavity treatment by an oral composition helps improve/design oral care compositions, especially those having a sensate.

An image of a pinna is captured. Based on the image of the pinna, a non-linear transfer function is determined which characterizes how sound is transformed at the pinna. A signal is output indicative of one or more audio cues to facilitate spatial localization of sound via the pinna, where the one or more audio cues is based on the non-linear transfer function.

A method for evaluating hearing of a user comprising: generating a baseline hearing profile for the user comprising a set of gain values based on a volume setting, each gain value in the set of gain values corresponding to a frequency band in a set of frequency bands; accessing a soundbite comprising a phrase characterized by a frequency spectrum predominantly within one frequency band; playing the soundbite amplified by a first gain in the frequency band; playing the soundbite amplified by a second gain in the frequency band; receiving a preference input representing a preference of the user from amongst the soundbite amplified by the first gain and the soundbite amplified by the second; and modifying a gain value, corresponding to the frequency band, in the baseline hearing profile based on the preference input to generate a refined hearing profile compensating for hearing deficiency of the user.

An apparatus for cortical mapping and method for using same are disclosed. The apparatus comprises a ECoG electrodes array, a stimulation pad, a neural interface processor, and a computing device for mapping eloquent cortical regions of a subject's brain without using exogenous stimulation and with high resolution.

A configurable system is used to evaluate stimulus sensitivity of a subject. An action channel provides a stimulus to the subject and a reaction channel receives a response from the subject. A signal pathway is connected to the action channel and to the reaction channel. A controller establishes loops within the signal pathway. Loop types include a transduction loop including the action channel and forming a path terminating in the signal pathway, and a channel loop including the action channel and terminating at a reference unit. Other possible loop types include an interface loop including the action channel, the reaction channel and the reference unit having an initial parameter value, and an adaptive loop including the action channel, the reaction channel and the reference unit whose parameter value is adapted based on the response from the subject. A method using the system is also described.
