While there are as many as 10,000 specific types of neurons in the human brain, generally speaking, there are three kinds of neurons: motor neurons (for conveying motor information), sensory neurons (for conveying sensory information), and interneurons (which convey information between different types of neurons).
Hale Construction was established by carpenter, Jonathan Hale, in 1996. At the time, the company consisted of just Jonathan and one other member of staff. Since then it has grown rapidly and currently employs over 130 people, all based in Neath.
The Hale House was a fire-damaged home in a wooded area of Beacon Hills, California. It was demolished to make way for new construction in Season 4. It is the former home of the Hale family. The house was burned down by a pair of arsonists at the behest of Kate Argent six years before the beginning of Wolf Moon. As a result, 8 people were killed. It was believed during Seasons 1 and 2 that all members of the Hale family except Derek Hale, Laura Hale and Peter Hale were killed in the blaze.
