When motor cortex instructs the spinal cord to move a limb in a specific direction, a large number of neurons in the motor cortex fire action potentials. Despite the activity of many neurons, movement is performed in a single, well-defined direction. How do the firing rates of the population of neurons in the motor cortex specify well-defined movements (e.g., a specific direction)?

2. Suppose next that we have even less knowledge of our patient, and we are only given the accuracy of the blood test and prevalence of the disease in our population. We are told that the blood test is 96% percent reliable, this means that the test will yield an accurate positive result in 96% of the cases where the disease is actually present. Gestational diabetes affects 7 percent of the population in our patient’s age group, and that our...
