Iconic memory
|
|
Iconic memory Short-lived visual sensory memory which lasts about 500 msec. Disrupted by masking (i.e. by a bright light). Tied to anatomical coordinates.
RELATED TERMS--------------------------------------
Memory
In the immune system, memory denotes an active state of immunity to a specific antigen, such that a second encounter with that antigen leads to a larger and more rapid response.
Masking
see blinding/masking.
Anatomical
1. Concerned with anatomy. 2. Concerned with dissection. 3. Related to the structure of an organism.
SIMILAR TERMS--------------------------------------
PREVIOUS AND NEXT TERMS--------------------------------------
Invasive
Medical tests that involve gaining entry into the body via a needle, tube, or hand.
Iron
A mineral in the body that works with protein to make hemoglobin, essential for the blood.
Irregular periods
Menstrual cycles that vary more than a few days in length from month to month are considered irregular. Most menstrual cycles are about four weeks long, with the normal range between 24 and 35 days.
Isolette
Similar to an incubator.
Ibotenic acid
Substance used in lesion studies. Destroys cell bodies of neurons but leave axons in tact.
Iconic memory
Interocular motion display
A motion display in which the motion stimulus in each eye of the observer is ambiguous, yet perception of coherent motion is possible if the subject combines motion information from both the eyes.
Isomorphistic approach
Belief that perceptual variations in the visual filed must be accounted for by analogous variations of neural activity. Roughly speaking, the neural distribution should look like the percept.
Isotropic
Any process or filter which is not directionally selective or biased. (As opposed to anisotropic).
Intercalated zones
Areas of cells falling between the parvocellular and magnocellular layers.
Inferior temporal cortex (IT)
Participates mainly in the acts of noticing and remembering an object's qualities. Cells do not have a retinotopic organization. Very large receptive fields. Virtually every cell's receptive field includes the foveal region. Receives input from V4. Some cells show a preferential response to such stimuli as hands or faces.
