What does Perrla stand for and how do I assess for it? PERRLA is an acronym that stands forthe pupil qualities your doctor should review during an eye exam. The list includes Pupils, Equal, Round, Reactive (to), Light, Accomodation. What follows is an explanation of how the doctor uses...
The PQRST method of assessing pain isa valuable tool to accurately describe, assess and document a patient's pain. The method also aids in the selection of appropriate pain medication and evaluating the response to treatment. What is included in a neuro assessment? A thorough neurologic assessment...
The vestibular system detects head rotation movements and sends signals to the nucleus of the trigeminal nerve, which impacts pupil size, triggering constriction of the pupil on the side opposite to the direction of head movement. This is known as the vestibular pupillary reflex, which improves ...
Assess pupils forsize,shape, andsymmetry. Pupils should usually becircularandsymmetrical. Typical pupil size varies between2 and 5 mm. Thepupillary light reflexis tested by applying alight stimulusto the pupil, usually a pen torch. Both pupils shouldbriskly constrictequallyin response to light. Thi...
Why is the pupillary light reflex important in the body? How is electron microscopy different from light microscopy? Explain how to use, handle, and clean a microscope. Why is it easier to get a three-dimensional perspective of objects v...
What is the pupillary response of the right eye when a light was shone into the pupil?What is the difference between cachexia and cataract?How does closing one eye affect the ability to judge distances?How do you calculate the magnification on a microscope?
We used linear regression as implemented in the mTRF toolbox43 to model the relationship between the speech signal and the neural data, and applied it in a backward direction to assess how well the attended and unattended speech envelopes could be reconstructed from the responses of the neuronal...

Why is the pupillary light reflex important in the body? Describe the response of rods and cones to different colors of light. How do the melanocytes respond to exposure to UV radiation? The process by which, when in the dark, the eyes become more sensitive to light? Which compound...
