AbstractDifferent types of attention alter subjective visual perception in fundamentally distinct ways. Previous studies have focused on covert attention without concurrent eye movements, showing that covert exogenous (involuntary) attention enhances contrast appearance of low-contrast stimuli while diminishing that of high-contrast stimuli, whereas covert endogenous (voluntary) attention uniformly enhances contrast appearance.

eLife assessment This important study adopts a comprehensive approach: functional connectivity, biochemistry, and psychophysics to reveal a holistic understanding of the relationship between GABA-ergic inhibition in the human MT+ region and visuo-spatial intelligence. The evidence supporting the conclusion is convincing.

AbstractThe prevailing opinion emphasizes fronto-parietal network (FPN) is key in mediating general fluid intelligence (gF). Meanwhile, recent studies show that human MT complex (hMT+), located at the occipito-temporal border and involved in 3D perception processing, also plays a key role in gF. However, the underlying mechanism is not clear, yet. To investigate this issue, our study targets visuo-spatial intelligence, which is considered to have high loading on gF.

AbstractThe canonical theory emphasizes fronto-parietal network (FPN) is key in mediating general fluid intelligence (gF). Meanwhile, recent studies show that multiple sensory regions in occipito-temporal border also play a key role in gF. However, the underlying mechanism is not yet clear. To investigate this issue, this study selects human MT complex (MT+), a region locates at the occipito-temporal border representing multiple sensory flows as a target brain area.
