Abstract: | "Infusions of a nitrosothiol, (+/-)S-nitroso-N-acetylpenicillamine or L-arginine into the accessory olfactory bulb (AOB) are capable of causing memory or learning-related synaptic plasticity in female mice. This is consistent with the ability of nitric oxide (NO), released spontaneously or by activation of the endogenous synthesizing system, to enhance a long-lasting increase in gain of AOB synapses; resulting in memory formation for male pheromones without mating. Hemoglobin, a NO scavenger, prevented this memory suggesting, in part, an extracellular action of NO in this functional plasticity" |
