Indirect spinothalamic pathways. These pathways mediate the affective and arousal components of pain, temperature, and simple tactile sensations. (A) The ascending axons in the paleothalamic tract synapse in the brainstem reticular formation and neurons in midline and intralaminar thalamic nuclei, which then project diffusely to the cerebral cortex including the cingulate gyrus. (B) In the spinoreticular tract, one group of ascending axons projects to the medullary reticular formation, and…

Diagram showing the course of fibers in the dorsal column. The fasciculus gracilis exists at all levels of the spinal cord and contains long ascending fibers from the lower limbs (shown in red). The fasciculus cuneatus exists in thoracic (T) segments above T6 (T1-T6) and cervical (C) segments (C1-C8) and contains long ascending fibers from the upper limbs (shown in blue). The axons of second-order neurons (neuron II) in the nucleus gracilis and cuneatus travel as internal arcuate fibers and…
