What is "hyperacuity"

n. sensory performance finer than the receptor grain

Hyperacuity is the seventh studio album by guitarist Greg Howe, released on June 6, 2000 through Tone Center Records.

Hyperacuity may refer to:

• Hyperacuity (album)
• Hyperacuity (scientific term)

The sharpness of our senses is defined by the finest detail we can discriminate. Visual acuity is measured by the smallest letters that can be distinguished on a chart and is governed by the anatomical spacing of the mosaic of sensory elements on the retina. Yet spatial distinctions can be made on a finer scale still: misalignment of borders can be detected with a precision up to 10 times better than visual acuity. This hyperacuity, transcending by far the size limits set by the retinal 'pixels', depends on sophisticated information processing in the brain.
