The representations of information concerning the number, size, density and surface of sets of objects in a visual image are separable along the occipito-parietal cortex and independently modulated by attention.
Functional brain scans of human participants show that the brain encodes other people's attention in enough richness to distinguish whether that attention was directed exogenously (stimulus-driven) or endogenously (internally driven).
Everyday soundscapes dynamically engage attention towards target sounds or salient ambient events, with both attentional forms engaging the same fronto-parietal network but in a push-pull competition for limited neural resources.
Primate amygdala neurons provide a coordinated representation of space and motivational significance whereby amygdala responses to visual stimuli predicting either rewards or aversive stimuli could influence spatial attention in a similar manner.
Populations of neurons in the macaque visual cortex are subject to shared fluctuations in gain; these signals exhibit anatomical and functional structure, and their variability is diminished under attention.
