Post Of The Week – Monday 10th April, 2017

1) Serotonin Transporter Protein Gene

I’ll admit this is a bit of a blow. For several years, I’ve been using a piece of video to go with some research which identifies the short form of the serotonin as a risk factor in the development of depression. The story is that people with this form are considerably more likely than people with the long form to develop depression if they experience three or more significant life events. The research was published in 2003. This link and this link explain that the research no longer stacks up. I’ll have to amend the webpage. We study something which is always changing.


2)  Children Doing Science

One idea that we explore when studying Piaget’s theory in Year 2 is that he underestimated children’s abilities to think logically at an early age. There are some interesting echoes of this idea in this description of children’s experience of science. The author intends to do something about it.


3) Heads Together

These two pieces of video from Heads Together are very different from each other but equally brilliant.


4) Broca’s Area

This article is a few years old but I have only just come across it. It explains the context to the core information we cover about localisation and lateralisation. Broca can be credited with understanding more about brain plasticity than is apparent from standard text book accounts.


5) Are Boys Smarter Than Girls?

This video has something balanced and interesting to say. This article goes into a bit more depth.


6) Alcohol And Personality Disorder

When looking at addiction, we often note that addiction is co-morbid with other health issues. This review looks at the effectiveness of treatment for people with alcohol addiction and personality disorder. Surprisingly little is known about treatment for such people. The best hope seems to be one based on formulation rather than diagnosis.


7) Rewriting Memory

This article looks at recent research into memory. Findings from optogenetics research in mice suggests that memories can go straight to the cortex as well as to the hippocampus. Memories need to be reinforced by signals from the hippocampus but nevertheless exist in the cortex when an event is first perceived. This challenges the view which has prevailed since the memory of HM was first studied in the 1950s.
