Estimation of the degree of autism spectrum disorder by the slow phase of optokinetic nystagmus in typical adults
2021, HeliyonCitation Excerpt :In addition, correlations between participants' AQ scores and the properties of fast phase OKN (i.e., mean eye position, peak velocity, and duration) were not found. Look-OKN and stare-OKN are characterized by low frequencies (<1 Hz) and high frequencies (1–5 Hz), respectively (Leguire et al., 1991). It is presumed that stare-OKN occurred as we intended because the frequency of OKN in the present study was 1.5–2.3 Hz.
Neuro-ophthalmic manifestations of cerebellar disease
2014, Neurologic ClinicsCitation Excerpt :Look OKN, a voluntary response that involves cortical activation, is characterized by large-amplitude, low-frequency, alternating voluntary pursuit and saccadic eye movements. In contrast, stare OKN is an involuntary, more subcortical response that consists of low-amplitude, high-frequency alternating eye movements.443–446 Various cortical, subcortical, and cerebellar structures are involved in the OKR, including those related to saccadic and smooth pursuit pathways.216,442,447
Instruction dependent activation during optokinetic nystagmus (OKN) stimulation: An FMRI study at 3 T
2010, Brain ResearchCitation Excerpt :It has been suggested that the terms stare OKN and look OKN be used to imply a distinction between conscious and unconscious regard of the target movement, respectively (Ter Braak, 1936; Holm-Jensen, 1984). Leguire et al. (1991) stated that the two main types of OKN are look, which is voluntary, and stare, which is involuntary. Look OKN is characterized by large amplitude (e.g., > 5° va) and low frequency (e.g., < 1 Hz) alternating voluntary pursuit and saccadic eye movements.
