The physical and physiological events at one end of an Abreu Brain Thermal Tunnel (ABTT) are reproduced at the opposite end. Thus, the ABTT enables the direct transfer of outputs from a brain core to an ABTT terminus without significant barriers. Accordingly, apparatuses, systems, devices, mechanisms, and methods use the ABTT terminus and the ABTT to measure the temperature of the brain core.

A method and device allowing a physiological signal, typically representative of brain activity, to be transcribed in the form of sensory signals perceptible to a human user, typically acoustic signals is provided. For this purpose, a physiological signal is acquired and then analysed in such a way as to detect therein patterns that are then parameterised in the time domain. One or more parameters of these patterns are used to determine one or more parameters of the generated sensory signals and/or to determine one or more parameters of temporal envelopes used to modulate the sensory signals. This method and device can be applied, in particular, to neuro-acoustic transduction.

The present invention provides a method for detecting events in an input signal. The method uses a volatile resistive switching component to detect the events in the input signal. The method comprising identifying the events based on sampling an output from the resistive switching component.

The present disclosure provides a method for optimizing T1-weighted magnetic resonance imaging of infant brains. Firstly, T1 and PD maps of infant brains at 0-12 months old are collected to obtain average T1 and PD values of WM and GM of the infant brains, and infants are classified into three age groups according to the characteristics of WM and GM T1 values of the infant brains. Then, the theoretical signal strength of the WM and GM of the infant brains generated from a 3D T1-weighted imaging sequence is calculated through Bloch simulation, and a theoretical optimal TI scheme of each group is determined according to the simulated WM/GM contrast characteristics under different TIs. Finally, the theoretical optimal TI scheme is applied to a target infant brain according to the designated age group for 3D T1-weighted magnetic resonance imaging.

Electrical non-invasive brain stimulation (NIBS) delivers weak electrical currents to the brain via electrodes that are affixed to the scalp. NIBS can excite or inhibit the brain in areas that are impacted by that electrical current during and for a short time following stimulation. Electrical NIBS can be used to change brain structure in terms of increasing white matter integrity as measured by diffusion tensor imaging. Together the electrical NIBS can induce changes in brain structure and function. The present methods and devices are adaptable to and configurable for facilitating the enhancement of brain performance, and the treatment of neurological diseases and tissues. The present methods and devices are advantageously designed to utilize modern electrodes deployed with, inter alia, various spatial arrangements, polarities, and current strengths to target brain areas or networks to thereby enhance performance or deliver therapeutic interventions.

The present wireless remote control device is a type of equipment with non-tethered optical stimulation. The characteristic of this device is designed to utilize a magnetic resonance technique to modify the deficits of the conventional magnetic induction or radio-frequency power source. Compared to the other devices of photostimulation, the advantages are as follow: there is a strong and even electromagnetic power; the cost is cheaper than the previous others; the device uses the receiver coil on an animal's head to receive the magnetic power from the transformation of the electrical power in the outside big coil, and thus the weight of the receiver coil on the head is very light. The light and miniaturized coil on the head without battery could give animals more convenience in freely movement, and the behavior of animals can be controlled by the effective extent of the electromagnetic field through photostimulation.
