This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. During 2005 we fully characterized the effects of local NPY receptor activation on glutamatergic and GABAergic inputs onto projection neurons of the BLA. Intriguingly, NPY had opposing effects on excitatory and inhibitory transmission. Hence, exogenous application of NPY attenuated glutamate release from extrinsic afferents, while facilitating GABAergic release from intrinsic sources. Data suggest that this occurs via activation of presynaptic NPY receptors, and we are currently investigating which receptor subtype mediate either of these two responses. In addition, we are investigating the direct postsynaptic effects of NPY receptor activation.
