A flat band of sensory fibers extending up from the medulla through the pons and midbrain to the thalamus.
A ribbonlike tract of nerve tissue conveying information from the spinal cord and brainstem upward through the midbrain to the higher centers. On each side a medial lemniscus acts as a pathway from the spinal cord, while an outer lateral lemniscus commences higher up and is mainly concerned with hearing.
A bundle of sensory fibers (lateral or exterior and median or interior) in the medulla and pons.
