Cover legend: Three-dimensional rendering of peptidergic neuronal inputs onto identified preautonomic neurons in the paraventricular nucleus of the hypothalamus. Presynaptic excitatory inputs (expressing vesicular glutamate transporter 2, pink) and inhibitory inputs (expressing vesicular GABA transporter, blue) are shown in close apposition to identified preautonomic neurons labeled with a retrograde tracer (gold). For more information, see the article by Bouyer and Simerly (pages 840–851).
