Louis Pierre Gratiolet (1815-1865): the cerebral lobes and fissures.

Early anatomists referred to parts of the brain as 'posterior' and 'anterior.' But after comparing many primate brains, Gratiolet noticed a pattern of folds or sulci and convolutions marked by fissures of increasing complexity in the more advanced mammalian brains. The primary fissures he could also identify in the smoother ape brains. He was the first to separate four brain lobes (frontal, par...

Louis, Lester and Pierre: Three Protocols for Location Privacy

Location privacy is of utmost concern for location-based services. It is the property that a person’s location is revealed to other entities, such as a service provider or the person’s friends, only if this release is strictly necessary and authorized by the person. We study how to achieve location privacy for a service that alerts people of nearby friends. Here, location privacy guarantees tha...

Louis Pierre Gratiolet (1815-1865) and His Contribution to the Study of Cerebral Convolutions in Primates

Louis Pierre Gratiolet (1815-1865) was one of the first modern anatomists to pay attention to cerebral convolutions. Born in Sainte-Foy-la-Grande (Gironde), he moved to Paris in 1834 to study medicine, as well as comparative anatomy under Henri de Blainville (1777-1850). In 1842, he accepted de Blainville’s offer to become his assistant at the Muséum d’histoire naturelle and progressively aband...

The bougie-aided cricothyrotomy.

191 Surgical cricothyroidotomy is considered a critical skill in emergency airway management, though it is rarely used and fraught with complications. A variety of approaches are taught, including both the standard and rapid four-step techniques. We report a case in which an air medical crew used a gum-elastic bougie (endotracheal tube introducer), a common device in many airway kits, to facili...
