| Popis: | Electrophysiological techniques have been used to study the projections of medial basal hypothalamic neurones. Neurones whose cell bodies were situated in the arcuate, ventromedial and dorsal medial nuclei and the periventricular area were antidromically activated by stimuli applied to the preoptic and anterior hypothalamic areas. Neurones were also identified in the same regions following stimulation of the paraventricular nucleus. These neurones were often found adjacent to other neurones which could be antidromically activated only from the junction of the pituitary stalk with the median eminence, but a few neurones were activated from both the median eminence and the more rostral regions. The latencies of these rostral projections were in the same range as those for the median eminence projections and calculated conduction velocities were below 1 m/sec. The possible neuroendocrine significance of these projections is discussed. |
