Anterior commissure - Wikipedia
The anterior commissure plays a key role in pain sensation, more specifically sharp, acute pain. It also contains decussating fibers from the olfactory tracts, vital for the sense of smell and chemoreception.
Anterior commissure: Anatomy and function - Kenhub
2023年10月30日 · The anterior commissure is a transversely oriented white matter fiber bundle which connects the two cerebral hemispheres of the brain concerned with the olfactory pathway. It also interconnects the amygdalas and temporal lobes of the brain. The anterior commissure is located in the anterior wall of the third ventricle.

2023年7月24日 · It is present throughout the length of the spinal cord and lies behind the anterior median fissure. Among the important pathways that decussate in the spinal cord via the anterior white commissure are the second-order neurons of the spinothalamic tract and the upper motor neurons of the anterior corticospinal tract.
A taxonomy of the brain’s white matter: twenty-one major tracts …
2022年10月10日 · Anterior Commissure. The anterior commissure (Fig. 2) is the second largest cerebral commissure. Its decussation is a prominent landmark in the brain and crosses through the striatum and internal capsule. Moving posteriorly, it is situated lateral and ventral to the striatum and medial to the claustrum.
The Six Major Anatomic Decussations with Clinical Correlation
2018年11月28日 · Axons from these neurons decussate in the anterior commissure and ascend in the ventrolateral portion of the spinal cord. There is a somatotopic arrangement with sacral fibers laterally placed followed by lumbar, thoracic, and cervical.
The evolution, formation and connectivity of the anterior commissure
2021年10月1日 · Here, we review the developmental mechanisms and connectivity of the anterior commissure across evolutionarily distant species, and highlight its potential functional importance in humans, both in the course of normal neurodevelopment, and as a site of plastic axonal rerouting in the absence or damage of other connections. 1. Introduction.
Three-Dimensional Anatomy of the Anterior Commissure: A
Background: The anterior commissure (AC) is one of the main commissural fibers of the brain. The commissural fibers are involved in bilateral integration and coordination of any normal brain activity.
Anterior white commissure - e-Anatomy - IMAIOS
This crossing (or decussation) occurs in the anterior white commissure and hence sensory information of pain, temperature, touch and pressure stimuli are transmitted through this commissure.
BrainInfo
The term decussation of the anterior commissure refers to the portion of the anterior commissure that crosses the midsagittal plane between the cerebral hemispheres. The center or caudal boundary of the decussation is the zero coordinate of stereotaxic space in most stereotaxic brain atlases in current use.
Decussation Of Anterior Commissure
Decussation Of Anterior Commissure (2000) J Cell Biol 149:951-968], the expression patterns described herein implicate a role for this interaction in central nervous system axon growth and guidance, especially at points of decussation .
