Your task
Within your group, prepare a 5 minute presentation of each of the 4 processes.1. Formation of the embryonic disc2. Formation of the neural tube3. Formation of the peripheral nervous system4. Formation of the brain
Use drawings to enhance your explanation.You have 20 minutes to prepare.During the next 20 minutes of class, I will
randomly pick a group and a number (1-3) to present. For each process, I will pick a different person. 4 people will present today, and it could be you, so be ready!

Literature Review
Assignment 1 due next class Good questions might resemble:
◦ How does serotonin affect mood?◦ What role does the hippocampus play in memory formation?◦ Is there a correlation between athleticism and cerebellum
volume? Guidelines for topics:
◦ Be prepared to tweak your question based on available evidence – there should be enough existing research on your topic! (>15 high quality peer reviewed articles in the past 50 years)
◦ Questions that are too broad (>30 meta-analyses in the past 20 years) will be too difficult to analyze thoroughly
◦ Start finding interesting articles and skim for question ideas Find, read, and annotate 5 articles by next class
