an·te·ri·or horn

[TA]
1. the frontal or anterior division of the lateral ventricle of the brain, extending forward from the Monro interventricular foramen;
See also: anterior column, gray columns.
2. the anterior horn or anterior (ventral) gray column of the spinal cord as appearing in cross section. The anterior horn is composed of the spinal laminae VIII and IX [TA] of Rexed with portions of VII also extending into its geographical boundaries in lumbosacral and cervical levels. The nuclei of the anterior horn are the anterolateral nucleus [TA] or ventrolateral nucleus [TAalt] (nucleus anterolateralis [TA]), anterior nucleus [TA] (nucleus anterior [TA]), anteromedial nucleus [TA] or ventromedial nucleus [TAalt] (nucleus anteromedialis [TA]), posterolateral nucleus [TA] or dorsolateral nucleus [TAalt] (nucleus posterolateralis [TA]), retroposterior lateral nucleus [TA] or retrodorsal lateral nucleus [TAalt] (nucleus retroposterolateralis [TA]), posteromedial nucleus [TA] or dorsomedial nucleus [TAalt] (nucleus posteromedialis [TA]), central nucleus [TA] (nucleus centralis [TA]), and the accessory nucleus and phrenic nucleus (both found in cervical levels only).
See also: anterior column, gray columns.

anterior horn

Etymology: L, ante + prior, foremost, cornu, horn, spina, spine; Gk, chorde, string
one of the hornlike projections of gray matter into the white matter of the spinal cord. The anterior horn contains efferent fibers innervating skeletal muscle tissue. Also called anterior column, ventral column, ventral horn.

Electrical stimulation of the anterior nucleus of thalamus for treatment of refractory epilepsy.
The CE Mark approval was based on data collected in Medtronic's clinical trial called SANTE([R])(Stimulation of the Anterior Nucleus of the Thalamus in Epilepsy).
The implanted device, which bilaterally stimulates the anterior nucleus of the thalamus but does not sense or respond to EEG activity, will be turned on in some patients but not in others during the trial's double-blind phase.
Medtronic DBS Therapy for Epilepsy is investigational and uses a pacemaker-like device to deliver individualized, targeted and precise electrical stimulation to a specific target in the brain called the anterior nucleus of the thalamus, which is part of a circuit involved in seizures.
