Activation of muscarinic receptors and GABA(B) receptors causes presynaptic inhibition of glutamatergic synaptic potentials at excitatory feedback connections in cortical structures. These effects may regulate dynamics in cortical structures, with presynaptic inhibition allowing extrinsic afferent input to dominate during encoding, while the absence of(More)
[1] Background concentrations, emission rates, and trends in emission rates for five trace gases are inferred for the northeastern United States from continuous atmospheric (CBrClF 2)) are referenced to CO and PCE (perchloroethylene, tetrachloroethene, C 2 Cl 4) to determine their urban/industrial source strengths and to test existing estimates of U.S.(More)
[1] Atmospheric mixing ratios of carbon monoxide (CO) and perchloroethylene (PCE, C 2 Cl 4) were measured above the canopy at Harvard forest, MA every half-hour for 3 years starting in January 1996. Pollution enhancements are strongly correlated with winds from the southwest, the direction of the New York City–Washington, D. C., corridor, as compared to(More)
[1] Long-term in situ observations of atmospheric concentrations of molecular hydrogen were monitored every 24 minutes for three years (1996–1998) above Harvard Forest, Massachusetts, in concert with measurements of carbon monoxide and twelve other trace gases. A seasonal cycle with a spring maximum and autumn minimum was observed. The diurnal cycle was(More)
