for detecting moving shadows. Hence, a rudimentary tectal map could have been present before the evolution of image-forming eyes and been coopted by them secondarily. Assuming the orientation of this map was fixed from the start relative to the external world, its retinal counterpart would have had to adjust to this to accommodate the image reversal that accompanies the conversion of a flat receptor array Amphioxus, motion detection, and the evolutionary origin of the vertebrate retinotectal map The axonal projection from the retina to the optic tectum maps visual information isomorphically from one to the other and serves as a model for the development of sensory maps more generally in the vertebrate brain. How or why this connection evolved is not known, nor why the midbrain is so important

the addition of oculocephalic reflex testing to vestibulo-ocular reflex testing as part of the clinical assessment for patients undergoing DNC (strong recommendation, moderate certainty in evidence).We recommend that one complete clinical assessment is sufficient for patients one year of age or older who are undergoing DNC (strong recommendation, moderate certainty in evidence).We suggest two complete accommodation of substitute decision maker/family resistance to DNC.5 The resistance to DNC may be framed in terms of legal rights like religious freedom, or it may relate to factors like shock, grief, or misunderstanding or mistrust of death determination. It is not advisable to exempt patients with objecting substitute decision makers/families from death determination procedures given the need

to reach the central veins: internaljugular, axillary, and femoral veins. The preferential site for centralvenous cannulation is the upper body especially in ambulatorypatients. The femoral vessels can better accommodate large cannulassuch as those used for extracorporeal membrane oxygenation.As previously discussed in section 3.3., US can help distinguishveins from arteries (Figure 4).

After the initial vessel puncture, US imaging of the vesselcan help the operator confirm the guidewire position in the vein.

Where necessary , the rash typically lasts for a period of seven to 10 days, resolving completely within two to four weeks. The most frequent complication of HZ is post-herpetic neuralgia (PHN), referring to persistent chronic pain after the resolution of the acute rash. Other complications can include herpes zoster ophthalmicus affecting the eye, herpes zoster oticus affecting the ear, disseminated or recurrent HZ skin
