Stimulation of the prefrontal cortex (PFC) has been shown to have an excitatory influence on dopamine (DA) neurons. We report here that, under nonstimulated conditions, the activity of DA neurons in the ventral tegmental area (VTA) also covaries, on a subsecond timescale, with the activity of PFC cells. Thus, in 67% of VTA DA neurons recorded in chloral(More)
Alpha-mangostin, a component of Garcinia mangostana Linn, is a xanthone derivative shown to have antioxidant and anticarcinogen properties. In this study, we first report the antimetastatic effect of alpha-mangostin in the human prostate carcinoma cell line PC-3. The results show that alpha-mangostin exhibited an inhibitory effect on the abilities of(More)
AIM To investigate the effect of l-stepholidine (SPD) on the frequency of spontaneous excitatory postsynaptic currents (sEPSC) in the pyramidal cells between layers V and VI in the prelimbic cortex (PL). METHODS A whole-cell patch clamp in rat brain slices was used. RESULTS SPD significantly increased the frequency of sEPSC in a concentration-dependent(More)
In this paper, the dynamic behavior of piezoelectric laminates is investigated. Thin piezoelectric layers are assumed to be embedded on the top and the bottom surfaces of the rectangular plate. The top and the bottom layers are taken as the actuator and sensor, respectively. Based on Von Karman theory, the geometrically nonlinear relation between strain and(More)
This paper takes CFBB as simulating object, which has characters of DG1025/17.4-II1 two legs furnace and with external heat exchanger. Combined with thermal process and combustion chamber working characteristics of practical unit, a general dynamic model arithmetic library of CFBB combustion chamber was set up based on a kind of graphic modeling real time(More)
Dopamine (DA) neurons in the ventral tegmental area (VTA) not only participate in reward processing, but also respond to aversive stimuli. Although GABA neurons in this area are actively involved in regulating the firing of DA neurons, few data exist concerning the responses of these neurons to aversive sensory input. In this study, by employing(More)
