Recent evidence suggests that reactive oxygen species (ROS), including superoxide, are not only neurotoxic but function as small messenger molecules in normal neuronal processes such as synaptic plasticity. Consistent with this idea, we show that brief incubation of hippocampal slices with the superoxide-generating system xanthine/xanthine oxidase (X/XO)(More)
Reactive oxygen species (ROS) typically are characterized as molecules involved in neurotoxicity and neurodegeneration. However, recent evidence from both neuronal and nonneuronal cells suggests that ROS also function as small messenger molecules that are normal components of signal transduction cascades during physiological processes. Consistent with this(More)
The induction of several forms of long-term potentiation (LTP) of synaptic transmission in the CA1 region of the mammalian hippocampus is dependent on N-methyl-D-aspartate receptor activation and the subsequent activation of protein kinase C (PKC), but the mechanisms that underlie the regulation of PKC in this context are largely unknown. It is known that(More)
Reactive oxygen species (ROS) have been suggested to act as cellular messengers that mediate signal transduction cascades in various cell types. However, little is known about their role in this capacity in the nervous system. We have begun to investigate the role of ROS, and that of nitric oxide (NO), in mediating mitogen-activated protein kinase (MAPK)(More)
The neural substrates of learning and memory are thought to involve use-dependent long-term changes in synaptic function, including long-term depression (LTD) of synaptic strength. One biochemical event hypothesized to contribute to the maintenance and expression of LTD is decreased protein phosphorylation, caused by a decrease in protein kinase activity(More)
An increasing number of studies in the environmental and resource economic literature suggest that preferences for changes or improvements in environmental amenities, from water quality to recreation, are spatially heterogeneous. One of these effects in particular, distance decay, suggests that respondents exhibit a higher willingness to pay (WTP) the(More)
IV. Community Input: Eugene Deshanvar. Eugene would like to address the board on issues of intellectual property, the minutes from the Academic Affairs Committee meeting on February 1 2012, and an update on his accountability. Eugene invites everyone to check out his story on his website. Regarding the minutes, Eugene says that he feels very sensitive to(More)
