Total daily mg is 200 (100 mg twice daily) 200 mg x 20 days = 4,000 mg over 20 days. If the medication is only available in 20 mg tablets, divide 4,000 mg by 20 mg.
4,000/20= 200 tablets
You could’ve also calculated daily tablets and multiplied by number of days. 200 mg a day divided by 20 mg tablets = 10 tablets daily. Times 20 days equals 200 tablets.
Split-brain patients have had surgery to cut the corpus callosum. Such a phenomenon was studied and monitored by two neuroscientists Roger Sperry and Michael Gazzaniga. After hard operation, patients felt quite good although the expectations weren't that good. Patients could perform all the activities they did before surgery, that was very surprising and innovational. But after several experiments, doctors discovered side effects and got back to study this process.
