Figure 2.
TBI patients and controls have similar caudal-rostral distributions of hypocretin neurons. The graphs show the average number of hypocretin neurons per section (mean values across all cases). Overall, TBI patients have fewer neurons, especially in the center of the hypocretin field. Level a: fornix touches the dorsal edge of the mammillary bodies; level b: fornix next to the paraventricular nucleus.
