Links About Brain Function
This week, as in an earlier post, I’m providing you with links to and brief descriptions of all the interesting articles that I’ve come across recently on one of the subtopics that I discuss on this site. This time the subtopic is “Function by Level of Organization” (under the main topic “From the Simple to the Complex”).
Cellular Level
Neuroscience: Making connections
This article describes a spectacular visualization method that make each individual neuron a different colour so that its connections with the other neurons around it can be better discerned. This technique represents a considerable step toward developing a “ connectome”—a complete map of the wiring of the mammalian brain.
Neurological Level
Scientists Map the Brain, Gene by Gene
This article discusses yet another tremendously ambitious brain-mapping project, but this time, the goal is to map all of the genes expressed in every neuron of the human brain! The Allen Brain Atlas project, funded by Paul Allen, co-founder of Microsoft, is intended to provide a global database that might be used, for example, to quickly identify the brain structures where the genes are expressed that are associated with specific mental disorders, such as schizophrenia and autism.
The effects that the kind of advanced automation methods used in the Allen Brain Atlas laboratory might eventually have on scientific thought in general.
Social Level
Why are we so nice? …because generosity wins.
Mathematical models predict it, and numerous experiments confirm it: what we call generosity is a key component of the strategies for winning certain games that explore human interactions.
In advanced capitalist societies, when catastrophes of natural and human origin occur, they give rise to behaviours of collaboration and co-operation not seen in the same communities under normal conditions.
Nature’s lessons for a more kind society.
Excerpt from a review of a book by primatologist Franz de Waal on the evolutionary bases of empathy, a phenomenon widely observed in the animal kingdom, and the critique of capitalism that is its inevitable corollary.
