Also called limen. the point at which a stimulus is of sufficient intensity to begin to produce an effect: the threshold of consciousness; a low threshold of pain.

limen [li´men] (L.) a threshold or boundary.limen of insula (limen in´sulae) the point at which the cortex of the insula is continuous with the cortex of the frontal lobe.limen na´si the ridge marking the boundary between the vestibule of the nose and the nasal cavity proper.li·men, pl. li·mi·na (lī'men, lim'i-nă), [TA] 1. Entrance; the external opening of a canal or space, such as limen insulae [TA]. 2.

Synonym(s): threshold (4) . [L.]threshold The value of a stimulus that just produces a response. Syn. limen.
absolute threshold The minimum luminance of a source that will produce a sensation of light. It varies with the state of dark adaptation, the retinal area stimulated, the wavelength of light, etc. Syn. light threshold. See photochromatic interval.
contrast threshold See differential threshold.
corneal touch threshold See corneal touch threshold.
differential threshold The smallest difference between two stimuli presented simultaneously that gives rise to a perceived difference in sensation. The difference may be related to brightness, but also to colour and specifically to either saturation (while hue is kept constant) or hue (while saturation is kept constant). The differential threshold of luminance is equal to about 1% in photopic vision. Syn. contrast threshold (if the difference is one of luminance); just noticeable difference (jnd). See Weber's law; contrast sensitivity.
light threshold See absolute threshold.
movement threshold 1. The minimum motion of an object that can be perceived. 2. The speed at which an object moving between two points just appears to be moving. See hyperacuity; phi movement.
