The result is a compensatory movement of the eyes. The vestibulo-ocular reflex (VOR) is a reflex that acts to stabilize gaze during head movement, with eye movement due to activation of the vestibular system, it is also known as the cervico-ocular reflex. The reflex acts to stabilize images on the retinas of the eye during head movement. Gaze ...
In medicine, the caloric reflex test (sometimes termed ' vestibular caloric stimulation ') is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal. This method was developed by Robert Bárány, who won a Nobel Prize in 1914 for this discovery.
This passive head rotation maneuver is testing the oculocephalic reflex, sometimes referred to as the Doll's Eye reflex. [11] The dorsal pons should be carefully considered when conducting neuroimaging studies. MRIs, or magnetic resonance imaging, are typically the preferred method.
Palmomental reflex: stroking on the thenar eminence of the hand causes contraction of mentalis muscles of the chin. Rooting reflex: Baby finds breast to suckle. Sucking reflex: Baby sucks breast / bottle / teat to get milk. Snout reflex: Involved in suckling. Glabellar reflex: May protect eyes in certain situations.
Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung; Hoffmann's reflex — also known as the finger flexor reflex; middle finger and thumb response. Test can indicate both neurological damage and nerve regeneration; often combined with the Babinski reflex test. Jaw jerk reflex
“If ever a plant said ‘don’t put me in your mouth’, this is it.”
Oculocephalic reflex, also known as the doll's eye, is performed to assess the integrity of the brainstem. Patient's eyelids are gently elevated and the cornea is visualized. The patient's head is then moved to the patient's left, to observe whether the eyes stay or deviate toward the patient's right; same maneuver is attempted on the opposite ...
The optokinetic reflex (OKR), also referred to as the optokinetic response, or optokinetic nystagmus (OKN), is a compensatory reflex that supports visual image stabilization. [1] The purpose of OKR is to prevent motion blur on the retina that would otherwise occur when an animal moves its head or navigates through its environment.
