Possible brain neuronal mechanisms of the microsaccadic activity modulated by the spatial and negative emotional attention. Microsaccadic production (green lines) (e.g., [25]) and emotional attention (red lines) (e.g., [35,36,37]) pathways. Emotional inputs can be divided into two pathways: (i) cortical and (ii) subcortical routes. Dotted lines indicate cortico-subcortical pathways. Note that the possible interactive pathways for emotional attention and microsaccades were limited within references for this review, although there exist various kinds of pathways
