Our previous study shows that intracerebroventricularly (i.c.v.) injected norepinephrine (NE) had different effects on the discharge of different firing patterns of magnocellular neurons in the paraventricular nucleus (PVN). In the present study we further classified antidromically identified magnocellular neurons into two groups: vasopressin (VP) and(More)
AIM To investigate the primary electrophysiological and pharmacological properties of the nucleus basalis magnocellularis (nbM) neurons. METHODS Single unit extracellular recordings from the nbM neurons were obtained with glass micropipettes in urethane-anesthetized rats. RESULTS Most nbM neurons responded to noxious but not innocuous mechanical,(More)
The problem of $$p$$ p -synchronization for a class of stochastic non-autonomous reaction-diffusion Cohen–Grossberg networks with mixed delays by using periodically intermittent feedback control is investigated in this paper. Some exponential synchronization criteria based on $$p$$ p -norm are obtained by utilizing some analysis methods. These proofs(More)
This paper presents a global and local finite-time synchronization control law for memristor neural networks. By utilizing the drive-response concept, differential inclusions theory, and Lyapunov functional method, we establish several sufficient conditions for finite-time synchronization between the master and corresponding slave memristor-based neural(More)
We present a new technique for the design of transformation-optics devices based on large-scale optimization to achieve the optimal effective isotropic dielectric materials within prescribed index bounds, which is computationally cheap because transformation optics circumvents the need to solve Maxwell's equations at each step. We apply this technique to(More)
The Q(weak) experiment has measured the parity-violating asymmetry in ep elastic scattering at Q(2)=0.025(GeV/c)(2), employing 145 μA of 89% longitudinally polarized electrons on a 34.4 cm long liquid hydrogen target at Jefferson Lab. The results of the experiment's commissioning run, constituting approximately 4% of the data collected in the experiment,(More)
The inhibitory effects of dopamine (DA) applied spinally on the wide dynamic range (WDR) neurons of dorsal horn in rats were studied with extracellular recording technique. 54 WDR units were tested from 43 rats. With a dosage of DA from 0.26 x 10(-6) to 1.58 x 10(-6) mol/kg, the inhibitory effect of the neurotransmitter on the responses of dorsal horn(More)
The present study investigated the effects of peripheral noxious stimuli on the spontaneous activity of the nucleus basalis magnocellularis (nbM) neurons in young, adult and old rats. Single unit extracellular recordings from the nbM neurons were obtained with glass micropipettes in urethane-anesthetized rats. A total of 104 units were antidromically(More)
