“…It also excels in perceiving fleeting and poorly illuminated stimuli A novel stimulus triggers immediate release of norepinepherine mainly in the right hemisphere (Edelman and Tononi, 2000;Goldberg, 2001;Mesulam, 2000a), and the noradrenergic neurons resist habituation, holding the attentional gates wide open to take in a generous exploratory data base (Tucker and Williamson, 1984). The input is then explored by induction, which utilizes pattern matching (Edelman and Tononi, 2000;Gentner et al, 2001) to define the boundaries (Barlow, 1985) and properties (Gattis, 2001;Hofstadter, 2001;Thagard, 2000) of the newly-discovered phenomena. This pattern matching is a right-hemisphere function (Gregory, 1970;Smith, 1989), as demonstrated by EEG (Molle et al, 2000) and functional MRI (Goebel et al, 1997;Shuren and Grafman, 2002), and verified by lesion studies (Bradshaw and Mattingly, 1995;Walker et al, 2001).…”
