For members taking a class of molecular neurobiology I sorry I am unable to have a presentation of molecular nurobiology in this week. I will present chapter14 next week. Actually I take a class every Thursday morning ,from 10:50 to 12:20. Thus I would like you to change a time or day of the class. I suggest the class will be had at 13:00 on May 24th or 9:30 on May 25th. If you have any schedule in these days please let me know. Iwai Sachio
