  Abstract:
The modulation of neuronal activities underlying spatial attention has been shown in many areas of human and primate cortex including area MT. In this study, we have investigated the common neuronal mechanism underlying attention and direction of motion processing at the level of neuronal population. Therefore we examined the responses of 254 isolated direction-selective neurons in area MT of a male macaque monkey while the animal was performing a spatial attention task. First, the strength of the attentional modulation across the neuronal population was estimated by fitting a line with a free slope and base using the method of non-linear least squares. The estimated attention modulation is 17.1
