LHA (Lateral hypothalamic area) projects to TM (Tuberomammillary nucleus)

Species: Rat
Result: present
Method: retrograde tracer
Sign: unknown
Evidence: CTB injected into dorsal (E4–E5) or ventral (E1–E2) TMN retrogradely labeled TuLH neurons. TuLH was the only site where these cells were pro-TRH positive, with CTB in about 64% (dorsal), 68% (E1) and 92% (E2) of TRH cells across 2 rats each. Retrograde labeling also appeared in the peduncular and perifornical lateral hypothalamus.

“The CTB results report TRH colocalization only in the TuLH, at 64%, 68% and 92% for each pair of rats, and list the peduncular and perifornical LH among the labeled sites.”
