Muscarinic antagonism is causally involved in motivation and incentivisation in healthy human participants, partially mediated via preparatory neural signatures, with implications for cholinergic treatment of Parkinson's disease.

Fast oscillations (30-150Hz), generated by internal brain mechanisms may be essential for the maintenance of healthy brain function.

Although activity in mouse V1 increases substantially during volitional running, such modulations in the foveal/central representation of primate V1 appear much smaller and suppressive.

States of elevated arousal and stable retinal images allow enhanced processing of threshold stimuli in the laminar microcircuits of area V4.

Psychophysical measurements using time pressure indicate that when attention is willfully deployed, a congruent scaccade is automatically planned, but the coupling is weak and can be rapidly broken.

High-resolution foveal imaging and micro-psychophysics reveal that the human oculomotor system finely adjusts drift motion of the eye in an acuity task to enhance retinal sampling, achieving sub-cell resolution.

Intact and local emotional biological motion exerted distinct influences on pupil responses, wherein the emotional modulation observed in intact biological motion is linked to individual autistic traits.
