The heart is the first organ to form in mammals. Cardiogenic lineages originate from paired regions of anterior lateral mesoderm, the cardiac crescent, soon after gastrulation and develop into parallel cardiac primordia that fuse to form the primitive heart tube along the ventral midline of the embryo. Subsequent events of looping, chamber maturation and alignment with the vasculature give rise...

This case expands our knowledge of the spectrum of manifestations of spontaneous intracranial hypotension. A 42-year-old man was seen for a third neurolog-ical opinion for obtundation. He presented with a 1-month history of new-onset, daily, intense, right-sided headaches (information about postural precipitation is not available). A magnetic resonance imaging (MRI) scan of the brain showed dif...

sensors, and the physical distribution of sensors can play a crucial role in a system’s functioning. For instance, the differences detected between two auditory organs lead an animal to locate a sound’s source (Rayleigh, 1877; Durlach and Colburn, 1978). A predator must use sensory input to determine its prey’s distance and heading as precisely as possible. The geometry of sensor location can g...
