Intracisternally Injected L-Proline Activates Hypothalamic Supraoptic, but Not Paraventricular, Vasopressin-Expressing Neurons in Conscious Rats

<table>Frontal sections showing vasopressin-expressing neurons in the hypothalamic SON and PVN.  (A) Intracisternal L-proline-injected rats.  (B) Negative control, ACSF-injected rats.  Representative higher magnification photographs are shown in (a), (b), and (c).  The arrows indicate the location of the magnification in the original photograph. f: fornix, 3V: third ventricle, OX: optic chiasm, opt: optic tract, LH: lateral hypothalamic area.</table>
