Neural Pathways What Are They?, How, Types, Dysfunction
The dorsal column-medial lemniscus pathway (DCML) is a sensory pathway of the central nervous system. It conveys sensation of fine touch, vibration, pressure, two-point discrimination and proprioception (position) from the skin and joints. Also known as the posterior column - medial lemniscus pathway, it consists of two parts.

The receptive field of a dorsal column nucleus has an inhibitory surround, which is a result of the indirect connections between mechanoreceptors and the dorsal column neuron via inhibitory interneurons. A) When no stimulus is present, the dorsal column neurons fire at a baseline rate.

Dorsal column: Medial lemniscus pathway and cuneocerebellar tracts Numerous cutaneous receptors detect and transmit sensory modalities such as light (discriminative) touch, vibration sense, proprioception, and two-point discrimination. Proprioception refers to the brain's ability to discern the actual spatial location of each part of the body.

Try out our quiz to test your knowledge on posterior column-medial lemniscus pathway: Spinothalamic tracts Characteristics The spinothalamic tracts carry pain, temperature, non discriminative touch and pressure information to the thalamus. The fibers forming the spinothalamic tracts are different from the fibers of the dorsal white column in.

Dorsal column-medial lemniscus (DCML) The DCML pathway transports information about vibration, proprioception and fine touch. Information from these modalities is transported in the dorsal column, two large white matter tracts located between the dorsal grey horns of the spinal cord. These dorsal columns are divided into two regions:

The medial lemniscus is a second-order neuron of the dorsal column-medial lemniscus pathway (DCML), which, with the somatotopic arrangement, transports the sensory spinothalamic information of conscious proprioception, vibration, fine touch, and 2-point discrimination of skin and joints of the body and head; from the caudal medulla to the ventra.

Dorsal column-medial lemniscus pathway The dorsal column pathway is one of the ascending tracts i.e. the neural pathways by which sensory information from the peripheral nerves is transmitted to the cerebral cortex.

The primary function of the dorsal column medial lemniscus (DCML) pathway is to convey sensory information regarding fine touch, two-point discrimination, conscious proprioception, and vibration sensations to the postcentral gyrus in the cerebral cortex from our skin and joints, excluding the head.

The dorsal column-medial lemniscus pathway is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception from the skin and joints. It transmits information from the body to the primary somatosensory cortex in the postcentral gyrus of the parietal lobe of the brain.
Dorsal Column Medial Lemniscus Pathway JuanknoeCarrillo
The dorsal column-medial lemniscal pathway (DCML) carries the sensory modalities of fine touch (tactile sensation), vibration and proprioception. Its name arises from the two major structures that comprise the DCML. In the spinal cord, information travels via the dorsal (posterior) columns.

The dorsal column system (sometimes referred to as the dorsal column-medial lemniscus) and the spinothalamic tract are two major pathways that bring sensory information to the brain (Figure 14.5.1). The sensory pathways in each of these systems are composed of three successive neurons.

The dorsal column-medial lemniscus pathway ( DCML) (also known as the posterior column-medial lemniscus pathway, PCML) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
