"It ain't what you do, it's the way that you do it": does obesity affect perceptual motor control ability of adults on the speed and accuracy of a discrete aiming task?

abstract：:5-Hydroxytryptamine (5-HT) has the most diverse set of receptors in comparison with any other neurotransmitter or hormone in the body. To date, seven families of 5-HT receptors have been characterized. A great number of studies have been published regarding the role of 5-HT and its receptors in seizures. However, with...
