eVox® Technology

The eVox system synergistically leverages sophisticated electrophysiological technologies and proprietary algorithms to map and measure elements of cognitive functioning.


Electroencephalography (EEG) is the measurement of the electrical patterns at the surface of the scalp that reflect cortical activity and are commonly referred to as “brainwaves”. Quantitative EEG (qEEG) is the digital analysis that is an extension of the visual interpretation of a traditional EEG. The EEG and the interpreted qEEG together are a modality for evaluating brain function as well as monitoring the progression of brain function over time following interventions such as medications or neurotherapy.

Heart Rate Variability and Electrocardiography

Heart rate variability (HRV) and heart rate via electrocardiography (ECG) measures the natural changes in the heart’s beat-to-beat interval. Research demonstrates that patients with cognitive impairment due to conditions such as dementia or depression present with significantly lower HRV compared to the norm. Due to the strong interplay between the central and autonomic nervous systems, it is important to assess the state of both the brain and heart electrophysiology when managing patients with cognitive impairment.

Event-related Potentials

Event-related potential (ERP) is a measured brain response that is the direct result of a specific sensory, cognitive, or motor event. More specifically, ERP measures the brain’s electrophysiological response to a series of stimuli. These may be auditory, visual, or electrical. ERP provides a real-time assessment of sensory information reception and the brain’s speed of processing information. Pathologies such as cognitive impairment compromise the brain’s normal ability to process billions of bits of information in milliseconds. ERPs can assess disruptions that lead to pathologies before they are symptomatic and noticeable. ERPs are measured by:

  • Visual processing
  • Auditory processing
  • Attention and vigilance (P3a)
  • Information processing and working memory (P3b)

“Having EEG, ERP, and ECG easily accessible allows me to confirm diagnosis and guide treatment protocols. The data analysis is extremely important clinically, and from a patient perspective, it gives them an opportunity to understand their own course of treatment.”

– Paul Buongiorno, MD (Psychiatrist, Board Certified as a Diplomate by the American Board of Psychiatry and Neurology)

inc-500ISO 13485 CertifiedThe eVox system is a biofeedback device not intended to act as a diagnostic tool. The assessment component of the device provides valuable information on patient physiology associated with underlying neuropsychiatric pathologies that physicians can use as a tool, along with medical expertise and the patients’ relevant medical history, to make better informed decisions regarding a patient’s health and to plan individualized biofeedback.
