Ventral pathway
Ventral pathway One of two theorized systems of visual information processing. Information though to progress toward the temporal cortex V1-> V2 -> V4 -> IT. Functions for analysis of object qualities such as pattern shapes, size and colors.

Ventricle
One of the two lower chambers of the heart.
Ventricles
The lower, pumping chambers of the heart. The heart has two ventricles - the right and left ventricle.
Ventricular fibrillation
A condition in which the ventricles contract in rapid and unsynchronized rhythms and cannot pump blood into the body.
Ventricular Fibrillation
An erratic, disorganized firing of impulses from the ventricles. The ventricles quiver and are unable to contract or pump blood to the body. This is a medical emergency that must be treated with cardiopulmonary resuscitation (CPR) and defibrillation as soon as possible.
Ventricular Rupture
In patients who suffer a significant heart attack, it is sometimes the case that the area of the muscle wall of the heart that is affected can become so weakened that it ruptures and leaks blood from the inner chamber of the heart.
Ventricular Septal Defect
The right and left ventricles lie next to each other in the heart. The septum is the membranous wall that separates them. A ventricular septal defect is a hole in the septum.
Ventricular tachycardia
A condition in which the ventricles cause a very fast heartbeat.
Ventricular Tachycardia
A rapid life-threatening rhythm originating from the lower chambers of the heart. The rapid rate prevents the heart from filling adequately with blood, and less blood is able to pump through the body.
Ventromedial Nucleus (VMN)
The part of the hypothalamus sensitive to excess glucose.
Ventromedial nucleus of the hypothalamus
Bilaterally, in the ventral (frontal) part of the middle (tuberal) region of the hypothalamus, a group of nerve cells associated with several vital functions such as food intake and sexual behavior.

Ventral pathway
Vieth-Muller circle
When the foveal centers are pointed at an object, the range for which images of all other objects fall on corresponding points of zero horizontal disparity. This differs from the perceived range of zero disparity, the Horopter.
Viewer centered coordinate system
The projection of an objects shape on the retina depends on the vantage point of the viewer.
Visual angle
A measurement of the area of the retina in degrees subtended by a stimulus. Roughly speaking the width of one's thumb at arm's length is approximately 2 degrees.
Visual phosphene
The visual perception resulting from non-photopic stimulation such as electrical stimulation of the cortex or pressing on the eyeball. Brinkdley & Lewin 1968) and Bak et al (1990) have shown that stimulation of the cortex produces visual pherceptions.
Vitreomacular traction syndrome
A traction-induced visual deficit in which partial posterior vitreous detachment is present in combination with persistent macular adherence.
