Abstract: A method for evaluating reading comprehension is provided. The method includes the steps of providing at least one printed passage of text; providing a test subject, the test subject wearing a device for measuring brain frontal lobe usage; requiring the test subject to read the printed passage; providing a question based on the printed passage for the test subject to answer; and determining whether the device measures brain frontal lobe usage. A system for performing the method is also provided.

Abstract: A method of assessing intracranial hemorrhage in a subject may include at a first time point: measuring, for a plurality of times, optical density (OD) value at first location on a first side of a head of the subject at a first time point, and a first corresponding location on a second side of the head of the subject. Change in optical density (?OD) is computed by subtracting each OD value measured on the first side from each corresponding OD value measured on the second side. A predetermined number of largest absolute ?OD values are eliminated from the ?OD values and a first average ?OD value is computed by averaging the remainder of ?OD values. The process is repeated at a second time point to obtain a second average ?OD. Progression of intracranial hemorrhage is determined based on a difference between the first average ?OD and the second average ?OD.

Abstract: A system, device and methods for quantitatively monitoring and evaluating changes in water and hemoglobin content in the brain in a non-invasive manner are provided. The system may be used for real-time detection and monitoring of brain edema and/or for an assessment of cerebral autoregulation.

Abstract: Functional near-infrared (fNIR) neuroimaging is used to assess credibility, detect deception, and implement a query methodology for determining deception via neuroimaging. Oxygenation levels of portions of the brain are imaged via fNIR spectroscopy and utilized to determine if the subject is telling a lie or a truth. In an example configuration, oxygenation levels in the inferior and/or middle prefrontal cortical areas of the brain, such as the bilateral dorsolateral prefrontal and/or inferior frontal cortex, are measured to determine if a subject is lying relative to telling the truth. An example system includes a portable, flexible, belt like sensing device that is positioned proximate the subjects scalp. Sensed neural activity is transmitted either through wired or wireless means, to a processor for analysis of the sensed neural activity. The query methodology utilizes an attestation assertion that mitigates variance in brain responses due to the length or form of a question.
