Tracking traumatic head injuries with the chemical senses

Traumatic Head Injuries in Sports

Head injuries are relatively common in football, accounting for up to 22% of all injuries in the sport(1). A significant fraction of these injuries are concussions, which are states of neural dysfunction resulting from head trauma in which there is the possibility of auditory abnormalities may also be observed as part of the concussive state. Concussions in football players have been linked wit...

Traumatic epilepsy after closed head injuries.

It has long been known that epilepsy may follow injury to the head. The relationship between the two events has been worked out in some detail for missile wounds of the head by Wagstaffe (1928), Ascroft (1941), and Russell and Whitty (1952), to mention but a few of many such studies, the opportunities for which were provided by the two world wars. The well-defined injury made study precise, and...

Chemical senses.

In the last decade, studies using approaches from molecular biology have substantially advanced our understanding of the early events in olfaction and taste. The many odorants that we can recognize may well interact with many distinct receptor proteins. Of the four taste qualities that we recognize, studies on salty and sour suggest that these tastes involve ion channels in the membrane of rece...
