Spinal Lamina Vi Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.

Spinal Lamina VI (Rexed layer VI) is located in the base of the dorsal horn and is primarily involved in processing proprioceptive information and motor control signals. [@jankowska1992]

Morphology

Lamina VI has distinct medial (proprioceptive) and lateral (interneuron) regions:

• Large projection neurons - in medial region
• Small interneurons - throughout lamina
• Dendritic trees - oriented toward dorsal horn

Molecular Markers

• VGLUT1 - primary proprioceptive marker
• VGLUT2 - mixed population
• PKCγ - in excitatory neurons
• Calbindin - calcium-binding protein
• Parvalbumin - in proprioceptive neurons

Normal Function

Lamina VI neurons process:

Disease Vulnerability
