 | | Epileptiform EPSPs in slices of piriform cortex from kindled rats displayed similarities in properties, locus of origin, and mechanism of generation to those previously studied in slices from normal rats in which epileptiform activity was induced by a brief period of bursting activity. | | | Previous studies in vivo and in vitro have shown that kindling from several locations in the limbic system induces the onset of epileptiform activity in the piriform (olfactory) cortex in the rat. | | | The experiments were performed in slices taken from rats that were previously kindled by conventional means. |

| | Zelano, Sobel and their colleagues plan to continue their fMRI studies to determine which portions of the brain are involved in very specific tuning of perception to a particular smell. | | | In separate trials, subjects were presented with both odorless and scented air and told to sniff at the sound of a tone. | | | The most active areas during this experiment were in the piriform cortex, located behind the eyes at the bottom of the temporal lobe. |

| | These observations, coupled with similar findings from studies of visuo-spatial processing in primate dorsolateral prefrontal and posterior parietal cortex, suggest the existence of distinct prefrontal-cortical systems that process the temporal stream of events in modality specific informational domains. | | | The present findings may reflect the strong reciprocal connectivity between OF and PIR and other structures involved in olfaction and behavior. | | | Neural firing patterns were examined in relation to task events on the current trial and variables associated with current sensory processing, events of recent past trials, and long-term associations involving the odor cues. |

| | Therefore, I am using intracellular labeling techniques to examine the patterns of connectivity among individual cells in piriform cortex and in the anterior olfactory nucleus. | | | This question is important for deciphering the functional significance of associational connections: a spatially restricted pattern would suggest that odor processing occurs by way of specific connections among subsets of neurons, while a widely distributed pattern of connections would suggest that odor processing occurs by a spatially distributed "ensemble" code. | | | Injections of anatomical tracers, such as HRP and PHA-L, have demonstrated that associational projections within piriform are highly distributed throughout the cortex. |

| | The circuits of pyramidal cells of piriform cortex are an example of a neural system that may need such balancing, as these neurons are known to be sensitive to the relative timing of the afferent and association input signals. | | | Not only piriform cortex is likely to be in need of such STDP-based balancing, it also is, in a sense, an ideal "hardware" for its implementation. | | | We develop a model of piriform cortex, which employs recently proposed principle of synaptic balancing, based on the STDP learning rule with a larger window of synaptic weakening. |
