Neuroanatomy: Brain Dissection

Cohan, Remy

Neuroanatomy (Ovine brain) Quiz

This quiz uses labelled still images from a dissected sheep (Ovis aries) brain and corresponding ex vivo MRI images from the same specimen. Because of the fixation/storage solution, MRI contrast may appear partly reversed compared with conventional in vivo MRI contrast. The specimen tissue was fixed in a solution composed of distilled water (94.73%), propylene glycol (3.84%), and phenoxyethanol (1.42%) - Sans formalin.

Note: You cannot submit each question separately. Choose the correct option for all questions, then scroll back up and press the submit button. There is no submit button at the bottom. The submit button is placed at the top by design, so you review your answers one last time as you scroll up to submit. Your hippocampus gets one last encoding opportunity; you never know, maybe long term potentiation even kicks in :)

Unlock rule: score at least 27 out of 30 to unlock the downloadable teaching slides, T1/T2 and PD (proton density) nifti MR images. You can then load the MRI files in the interactive NIfTI viewer on this website.
