the exam that relate to the assigned chapters from VS Ramachandran s The Tell Tale Brain I expect you to have read the chapters understood them and thought about them I won t try to trick you if I ask questions about these chapters but I will at least include questions that test whether you did the readings Finally you will spend some time in each Friday quiz section discussing the week s chapter Test questions may be inspired by these discussions Assigned chapters see additional notes in the TT Brain Reading Schedule on the course website Introduction No Mere Ape Chapter 1 Phantom Limbs and
