Detecting Fear of Heights Response to a Virtual Reality Environment Using Functional Near-Infrared Spectroscopy

Abstract: To enable virtual reality exposure therapy (VRET) that treats anxiety disorders by gradually exposing the patient to fear using virtual reality (VR), it is important to monitor the patient's fear levels during the exposure. Despite the evidence of a fear circuit in the brain as reflected by functional near-infrared spectroscopy (fNIRS), the measurement of fear response in highly immersive VR using fNIRS is limited, especially in combination with a head-mounted display (HMD). In particular, it is unclear to wha… Show more

“…35 iVR has been applied in treating specific phobias and anxiety disorders by setting up virtual environments that expose the patients to their feared objects or environments in the absence of actual harm. Using fNIRS to simultaneously record the brain responses, previous iVR-fNIRS work has explored the neural correlates of acrophobia (i.e., fear of height) 31,46,60 and public speaking anxiety. 41 In both cases, exposure to feared situations led to greater activations in the DLPFC and the medial PFC, which might reflect modulated emotional processing in the PFC and subcortical areas.…”

“…Electroencephalography (EEG) studies reported that cybersickness was associated with increased spectral power in delta, theta, and alpha frequency bands through frequency and time–frequency spectral analysis 13 , 14 . However, EEG is susceptible to motion artifacts and electrical signal interference when interacting with virtual reality technology 16 . Among functional neuroimaging techniques, the functional near-infrared spectroscopy (fNIRS) has advantage of being less susceptible to motion artifacts and electrical noises and higher spatial resolution than EEG 16 .…”

Among functional neuroimaging techniques, the functional near-infrared spectroscopy (fNIRS) has advantage of being less susceptible to motion artifacts and electrical noises and higher spatial resolution than EEG 16 . It is a non-invasive optical method that indirectly detects cortical activity based on hemodynamic response and is considered a promising neuroimaging technique for the virtual reality tasks 17 .…”
