1. Homogenates of bovine retinas were used to study the capacities of two new dopamine (DA) receptor agonists, e.g. YM 435 and A 77636, to interact with D1 receptors. 2. Adenylate cyclase experiments. YM 435 and A 77636 enhanced cAMP

With advancing age, monkeys develop deficits in spatial working memory resembling those induced by lesions of the prefrontal cortex (PFC). Aged monkeys also exhibit marked loss of dopamine from the PFC, a transmitter known to be important for proper PFC

The aim of the present study was to determine whether dopamine affects NaCl reabsorption in the medullary thick ascending limb of the loop of Henle. Basolateral dopamine (10(-6) M) significantly inhibited Cl- reabsorption in the in vitro microperfused rat medullary

The prefrontal cortex guides behaviors, thoughts, and feelings using representational knowledge, i.e., working memory. These fundamental cognitive abilities subserve the so-called executive functions: the ability to inhibit inappropriate behaviors and thoughts, regulate our attention, monitor our actions, and plan and

Cognitive impairment has been found across all subtypes of schizophrenia. The location and function of dopamine-1 receptors (D1Rs) make them attractive targets for the treatment of cognitive impairment in schizophrenia. Here we investigate the systemic effect of a D1R agonist
