The Livermore Valley rarely experiences severe weather. The greatest annual rainfall during the period between 1931 and 1990 was 1041 mm (41 inches)(NOAA, 1980-1990). During the 5 years between 1986 and 1991, California experienced less than normal precipitation, which is 379 mm (14.9 inches).
Abstract. Dopamine D2-autoreceptors play a key role in regulating the activity of dopamine neurons and control the synthesis, release and uptake of dopamine. These G i/o-coupled inhibitory receptors play a major part in shaping dopamine transmission.2-autoreceptors also regulate dopamine transmission by increasing the activity of DAT (Cass and Gerhardt, 1994, Dickinson et al., 1999, Mayfield and Zahniser, 2001, Schmitz et al., 2002, Wu et al., 2002 and Benoit-Marand et al., 2011).
Oxytocin neurons themselves express oxytocin receptors, and vasopressin neurons express vasopressin receptors, so dendritically-released peptides autoregulate the supraoptic neurons. Francoise Moos and Phillipe Richard first showed that the autoregulatory action of oxytocin is important for the milk-ejection reflex.
