I investigate the motion system as a model to study the link between sensation,
perception, and decision making. To this end I use a combination of psychophysical
tasks (humans and monkeys) as well as single and multi-electrode recording
techniques in awake behaving monkeys. Some of the main research topics are: |
The relation between single unit firing rate and behavioral choice on a trial
by trial basis. Thiele, Distler, Hoffmann,EJN,1999; Cardoso de Oliveira, Thiele, Hoffmann, J. Neurosci. 1997. Thiele, Hoffmann, EBR 2008 Chen et al. 2012, J. Neurophysiology. |
The neural basis of chromatic motion processing has been (and still is) a matter
of debate for almost thirty years. We investigated whether chromatic motion sensitivity
of neurons in macaque area MT match monkey psychophysical sensitivity
using the opposed motion stimulus (Cavanagh P, Anstis S, 1991, Vis. Res., 31: 2109-2148). Our findings testify that
area MT is indeed a principal component of the neuronal substrate for color-based
motion processing. Thiele, Dobkins, Albright, J. Neurosci. 1999, Thiele, Dobkins, Albright, Neuron, 2001 However, we also found a yet unreported difference between human and monkey psychophyisical chromatic motion sensitivity.
