Local circuit neurons in the dorsolateral prefrontal cortex (dPFC) of monkeys have been implicated in the cellular basis of working memory. To further elucidate the role of inhibition in spatial tuning, we iontophoresed bicuculline methiodide (BMI) onto functionally characterized neurons in the dPFC of monkeys performing an oculomotor delayed response task.(More)
Studies on the cellular mechanisms of working memory demonstrated that neurons in dorsolateral prefrontal cortex (dPFC) exhibit directionally tuned activity during an oculomotor delayed response. To determine the particular contributions of pyramidal cells and interneurons to spatial tuning in dPFC, we examined both individually and in pairs the tuning(More)
A simple, sensitive and selective method is proposed for the spectrophotometric determination of drugs, viz. ampicillin, penicillin V, amoxycillin, cloxacillin, cefadroxil, ceftezoxime, griseofulvin, streptomycin, nicoumalone and acebutolol HCl, based on their reactivity with iodine. The method involves the addition of excess iodine of known concentration(More)
The province of Punjab is the main food basket of India. In recent years, many regions of Punjab are facing acute waterlogging problems and increased secondary salinity, which have negative impacts on food security of the nation. In particular, these problems are more pronounced in the Muktsar district of Punjab. The observed groundwater levels trend(More)
