Methods and systems are disclosed for discovery of knowledge, interest and experience of individuals indicated by measured psychophysiologic response (e.g., electroencephalograph) to sensible stimuli (e.g., images). Stimuli are selected to explore targeted topics described in various levels of detail and sub-categories organized as hierarchal trees. The degree of psychophysiologic response to stimuli associated with sub-categories of topics in the hierarchal tree guides selection of additional stimuli to systematically explore hierarchal tree nodes, levels and branches to discover the extent of knowledge, interest or experience related to the targeted topic. A system enabling these methods provides archival and search of hierarchal trees associated with topics of interest, target and non-target stimuli, stimulus dataset generation, editing and presentation, psychophysiologic data collection and processing via local and remote resources, evoked response detection, characterization and scoring, and association of indications of knowledge, interest or experience with regards to facets of the targeted topic.

Methods, devices, and systems are disclosed for producing cognitive and/or sensory profiles. In one aspect, a method to provide a cognitive or sensory assessment of a subject includes selecting a profile category from among a cognitive performance profile, a sensory performance profile, and a cognitive and sensory performance profile, presenting a sequence of stimuli to a subject, the sequence of stimuli based on the selected profile category, acquiring physiological signals of the subject before, during, and after the presenting the sequence of stimuli to produce physiological data, and processing the physiological data to generate an information set including one or more quantitative values associated with the selected profile category.

A system for evaluating neurologic dysfunction of a subject includes an odorant generator configured to deliver an odorant stimulation to the subject, an auditory generator configured to deliver an audible stimulation to the subject, a vibrotactile stimulator configured to generate a somatosensory stimulation to the subject, a plurality of electrodes configured to be attached to the subject at respective different locations, and at least one processor. The plurality of electrodes are configured to collect neural signals from the subject as a result of the odorant stimulation, the audible stimulation, and the somatosensory stimulation. The at least one processor is configured to process the neural signals from the plurality of electrodes and generate an assessment of neurologic dysfunction of the subject.

A non-invasive product customization system and a method of customizing a product formulation is provided. Brain activity of a user is detected in response to an input of a product formulation into a brain of the user via a sensory nervous system of the user. A mental state of the user is detected based on the detected brain activity. The product formulation is modified based on the determined mental state of the user. The modified product formulation may be presented to the user in a manner that modulates the mental state of the user.

A system for delivering sensory stimulation a sensor; a sensory stimulator configured to deliver sensory stimulation to a patient during a sleep session, the sensory stimulation having varying stimulation intensity levels; and a computer system. One or more physical processors being programmed with computer program instructions which, when executed cause the computer system to: determine sleep stage information of the patient based on brain activity information of the patient during the sleep session from the sensor; provide input to the sensory stimulator based on the determined sleep stage information of the patient, the provided input causing the sensory stimulator to deliver the sensory stimulation to the patient; obtain stimulation response information from the patient, the stimulation response information including patient brain response to the delivered sensory stimulation; and determine a range of the stimulation intensity levels within which the patient brain response reaches a threshold.

A system for assessing brain health of a user includes an electronics module including an active brainwave sensor that collects channels of electroencephalography (EEG) brainwave data, a plurality of biological sensors, and a stimulation device.

The plurality of biological sensors simultaneously measure the body's response to stimulants for recordation by the electronics module.

Technology for the transition of light and sound over long distances, e.g. TV and radio, has revolutionized society. On the contrary, the technology to perceive a smell remotely is in its infancy, and has severe limitations such as latency, residual and infidelity. A system and methods are disclosed to allow smells to be perceived remotely. It is based on the brain waves associated with the olfactory bulb.
