Re: [Channel-talkbio] Unit 10 Neurobiology

From: Mary Johnston <mjohnston@haverhill-ps.org>

Hey Karen and Ed,
  I don't know about you two but I found this unit to be quite heavy in
a lot of material. I was really interested, however, in the
neurogenesis aspect of the unit. That old saying that "You can't teach
an old dog new tricks," turns out to be wrong because studies have shown
that stimulating environments result in the creation of neurons. Rats
given stimulating environments had 15% more neurons than rats kept on
boring ordinary lab situations. I think we have all experienced this in
our classrooms. On days, when we have a novel activity or lab or fun
video, the kids are much more receptive than on a day when we are doing
lecture notes. Of course, we need both activities to complete our
learning, but if we stagnate and always do the same thing, I think
students don't learn material as well. I think the same is true going
in the other direction. If you did a lab every day and never had an
opportunity for direct teaching students would probably miss out on some
vital pieces of information. I guess I am an advocate for trying to do
a little bit of everything each week to keep kids stimulated and keep
those neurons growing!
     Another aspect that I wanted to discuss was the medical use of
marijuana. I am against this. I was just watching on TV the other day
that students in California high schools where the medical use of
marijunana is legal are getting signed notes from doctors that say
things like stress should allow them to be able to smoke pot. Right on
school grounds kids are lighting up and fighting to get away with it.
Of course, marijuana is illegal on school grounds, but you can easily
see that this has opened the door to make getting high for non-medical
reasons a lot easier. Soon doctor's notes will be faked or sold and
people will abuse the system. Yes, there are a small amount of people
that marijunana might comfort or help out, but the vast majority of
people who smoke it are not doing so for medical reasons and it is they
who will try and take adavnatage of the system. Besides, there are so
many over-the counter and prescriptio analgesics as it is. Do we really
need to "numb" our society any more? Let me know what you think.
Mary Johnston
