The Neurobiology Of The Amygdala PDF Download

Fear and anxiety play essential roles in almost every person's life. Fear is the belief that something dangerous or unfortunate may happen in the future. Fear and anxiety are regarded to be unpleasant perceptions with few exceptions, such as the pleasure or joy that people may experience from watching horror movies.
