Antidromic identification of neurons in the ventrolateral part of the medulla oblongata with ascending projections to the preoptic and anterior hypothalamic area (POA/AHA).
Seventy neurons in the ventrolateral medulla oblongata were antidromically activated by electrical stimulation of the preoptic and anterior hypothalamic area (POA/AHA) in female rats under urethane anesthesia. These identified cells were located within and adjacent to the nucleus reticularis lateralis and could be readily distinguished into at least two types of neurons, designated as "fast' and "slow' cells, on the basis of their waveform and conduction velocity.
