Predictive coding offers a potentially unifying account of cortical function--postulating that the
core function of the brain is to minimize prediction errors with respect to a generative model …

When we attempt to fix our gaze, our eyes nevertheless produce so-called'fixational eye
movements', which include microsaccades, drift and tremor. Fixational eye movements …

Our eyes continually move even while we fix our gaze on an object. Although these
fixational eye movements have a magnitude that should make them visible to us, we are …

Contrary to common wisdom, fixations are a dynamically rich behavior, composed of
continual, miniature eye movements, of which microsaccades are the most salient …

An important task in vision is to detect objects moving within a stationary scene. During
normal viewing this is complicated by the presence of eye movements that continually scan …

A brief visual target stimulus may be rendered invisible if it is immediately preceded or
followed by another stimulus. This class of illusions, known as visual masking, may allow …

It has been demonstrated that electrical stimulation of the retina can produce visual percepts
in blind patients suffering from macular degeneration and retinitis pigmentosa. However …

When viewing a stationary object, we unconsciously make small, involuntary eye
movements or 'microsaccades'. If displacements of the retinal image are prevented, the …

Recent studies suggest that certain cellular sensory systems display fold-change detection
(FCD): a response whose entire shape, including amplitude and duration, depends only on …

Sensory information is encoded both in space and in time. Spatial encoding is based on the
identity of activated receptors, while temporal encoding is based on the timing of activation …
