Given that Gray behavioral-brain systems and AFECT combined nature emotional-affective model, a biological model of personality is introduced which forms individual differences  so that each activity results in calling of different reactions. This  present research aimed to  provide relational  patterns of behavioral-brain systems with dimensions of combined nature emotional-affective model. Statistical population contained 220 university students from ShahidMadani University of Azarbaiijan that sampling method was categorical clustering  and subjects were tested by Jackson Personality Questionnaire  and AFFECT. To analysis  data, Pearson  correlation coefficient  and simultaneous multi regression were done. Results  of  regression showed that all dimensions of AFECT combined nature emotional-affective model  are predictable from  relational  patterns of Gray behavioral-brain systems with significance in level 0/01, except anger and spree, the highest percent of prediction belongs to emotional nature of control and the lowest percent of prediction belongs to anger  so that 16% variances former as well as7% variance of  later are predictable from Gray theory. The  highest  percent of prediction is for depression affect which 15% of changes as well as the lowest  prediction was for spree which 8% of changes were predictable from Gray theory. Collectively,  results from research  on statistical population is indicator of rational patterns between theories of Gray behavioral-brain systems and AFECT combined nature emotional-affective model.
