Application Fields
Auditory brainstem responses (ABR) or brainstem auditory evoked potentials (BAEP) measure the electrical activity of the brain’s auditory system in response to the presentation of acoustic stimuli (e.g., clicks, chirps,[…]
Virtual reality involves placing participants in simulated computerized environments. Often, participants wear a headset with goggles that project 3D images or videos onto their retinas, creating the sensation of immersion[…]
Child development is a fascinating area of research that is often complicated by the unique requirements (e.g., excess movement, emotional responses, sensitivity to stimuli, limited attention spans, limited verbal communication)[…]
Brain-Computer Interfaces (BCIs) consist of hardware and software solutions that use the electrical activity of the brain to interact with and/or control external devices (e.g., machines). Traditionally, BCIs were home-grown[…]
Many researchers have teaching commitments, and we recognize the time and effort that goes into lesson planning with the goal of transferring knowledge about complex topics like electrophysiology and brain[…]
Electroencephalography (EEG) is the measurement of the electrical activity of the brain through specialized electrodes placed on the head. We offer passive, active, gel-based, saline, and dry-electrode technologies, so researchers[…]
Functional magnetic resonance imaging (fMRI) uses rapidly oscillating magnetic fields to measure changes in blood oxygenation level dependent signaling (BOLD) throughout the brain, which is often considered to be a[…]
Magnetoencephalography (MEG) uses high-resolution coils coupled to superconducting quantum interference devices (SQUIDs) to measure the magnetic fields associated with the electrical currents produced by neuronal activation. Unlike EEG or fNIRS,[…]
Transcranial magnetic stimulation (TMS) uses electromagnetic coils to induce brief electrical activation of brain cells in specific cortical regions. Depending on the stimulation pattern, duration, and frequency, the effects of[…]
Recording videos of participants during EEG data collection is often helpful for informing both pre-processing and interpretation of the resulting EEG signals. This is particularly useful for applications in which[…]
One inherent limitation of EEG & ERP data collection is that it is virtually impossible to pinpoint the underlying neural generator (e.g., source) of the electrical signal recorded from the[…]
The average person spends about one-third of their life sleeping. A good night’s sleep is positively correlated with general well-being and cognitive function, and understanding changes in brain activity during[…]
An event-related potential (ERP) or evoked-potential (EP) is a stereotyped neurophysiological response to an internal (e.g., thought or emotion) or external (e.g., image or sound) stimulus. Often, to record a[…]
Functional near infrared spectroscopy (fNIRS) uses different wavelengths of near infrared light to measure changes in blood oxygenation and deoxygenation (i.e., the hemodynamic response) across the cortex, which is often[…]
Hyperscanning involves recording brain activity from more than one person at the same time. There are many advantages to these types of paradigms – particularly when it comes to understanding[…]
Mobile brain/body imaging (MoBI) is a rapidly evolving research area, due, in part to advancements in wearable electrophysiological devices and sensors. Historically, movement of electrode lead wires during EEG data[…]
Peripheral physiology can be used to infer activation of the autonomic nervous system in response to various cognitive processes. Peripheral signals (e.g., heart rate [ECG], muscle activation [EMG], eye movements[…]
We offer professional software solutions for data acquisition, real-time visualization of underlying EEG signals in hostile recording environments (e.g., during fMRI recordings), data cleaning / pre-processing, and statistical analysis. Our[…]
Transcranial Electrical Stimulation (tES) is a general term used to describe noninvasive brain stimulation methods in which brief pulses of low-intensity electrical current are delivered to the brain through electrodes[…]
