The laser projections left visual echoes on the surroundings, which we were able to capture through long-exposure photography.
Attention was either validly (80%) or invalidly (20%) cued to the right or left visual hemifield.
Although photophobia remained on the seventh day following the start of chemotherapy, her left visual acuity temporarily improved.
On the sixth day following the first course, her left visual acuity improved from finger movement to 0.06.
The effects of nicotine upon top-down modulation were investigated by comparing occipital activity when attending to the right vs. left visual hemifield under placebo and nicotine.
Contrasts of left visual field trials minus right visual field trials, and right visual field trials minus left visual field trials revealed activations in the contralateral visual cortices in line with the lateralized presentation of the stimuli.
In contrast a reaction time advantage was found for upper versus lower and right versus left visual field.
A dental drill was used to make a hole (3.0 mm diameter) in the skull above the left visual cortex.
We modeled the BOLD response using a separate explanatory variable (EV) for each of the three stimulus types (left visual field, right visual field, and bilateral).
After another six months, the enlarged pathology (diameter of about 680 µm) resulted in pronounced paracentral sensitivity loss that left visual acuity unaffected.
In this analysis, there were four EVs at the subject level: right visual field trials, left visual field trials, coactivation, and non-coactivation trials.
