Tobacco use in developed countries is estimated to be the single largest cause of premature death. Nicotine is the primary component of tobacco that drives use, and like other addictive drugs, nicotine reinforces self-administration and place preference in animal studies. Midbrain dopamine neurons normally help to shape behaviour by reinforcing biologically(More)
The smooth muscle (SM) alpha-actin gene activated during the early stages of embryonic cardiovascular development is switched off in late stage heart tissue and replaced by cardiac and skeletal alpha-actins. SM alpha-actin also appears during vascular development, but becomes the single most abundant protein in adult vascular smooth muscle cells.(More)
K+ and Rb+ conductances (GK+ and GRb+) were investigated in two delayed rectifier K+ channels (Kv2.1 and Kv3.1) cloned from rat brain and a chimera (CHM) of the two channels formed by replacing the putative pore region of Kv2.1 with that of Kv3.1. CHM displayed ion conduction properties which resembled Kv3.1. In CHM, GK+ was three times greater than that of(More)

Flow control is attracting an increasing attention of researchers from a wide spectrum of specialties because of its interdisciplinary nature and the associated challenges. One of the main goals of The Collaborative Center of Control Science at The Ohio State University is to bring together researchers from different disciplines to advance the science and(More)
Addictive drugs have been hypothesized to access the same neurophysiological mechanisms as natural learning systems. These natural learning systems can be modeled through temporal-difference reinforcement learning (TDRL), which requires a reward-error signal that has been hypothesized to be carried by dopamine. TDRL learns to predict reward by driving that(More)
