The Human Brain Can Create Structures in Up to 11 Dimensions, new and interesting findings at https://www.sciencealert.com/science-discovers-human-brain-works-up-to-11-dimensions

Interesting stuff, excerpt:

“We found a world that we had never imagined,” said lead researcher,neuroscientist Henry Markram from the EPFL institute in Switzerland.

“There are tens of millions of these objects even in a small speck of the brain, up through seven dimensions. In some networks, we even found structures with up to 11 dimensions.”

Just to be clear – this isn’t how you’d think of spatial dimensions (our Universe has three spatial dimensions plus one time dimension), instead it refers to how the researchers have looked at the neuron cliques to determine how connected they are.

“Networks are often analysed in terms of groups of nodes that are all-to-all connected, known as cliques. The number of neurons in a clique determines its size, or more formally, its dimension,” the researchers explained in the paper.

Human brains are estimated to have a staggering 86 billion neurons, with multiple connections from each cell webbing in every possible direction, forming the vast cellular network that somehow makes us capable of thought and consciousness.

I am not sure if I agree based on my personal experience and observations.

Excellent document that should be reviewed by any professor and collaborating student.  Find at http://www.aaal.org/?page=EthicsGuidelines

Excerpt:

Professional development programs are based on different theories of how students learn and different theories of how teachers learn. Reviewers often sort programs according to design features such as program duration, intensity, or the use of specific techniques such as coaches or online lessons, but these categories do not illuminate the programs’ underlying purpose or premises about teaching and teacher learning. This review sorts programs according to their underlying theories of action, which include (a) a main idea that teachers should learn and (b) a strategy for helping teachers enact that idea within their own ongoing systems of practice. Using rigorous research design standards, the review identifies 28 studies. Because studies differ in multiple ways, the review presents program effects graphically rather than statistically. Visual patterns suggest that many popular design features are not associated with program effectiveness. Furthermore, different main ideas are not differentially effective. However, the pedagogies used to facilitate enactment differ in their effectiveness. Finally, the review addresses the question of research design for studies of professional development and suggests that some widely favored research designs might adversely affect study outcomes.

I am so relieved about reading about this research.  Find details in Scientists Say That Being Forgetful Is Actually A Sign You Are Unusually Intelligentat https://www.littlethings.com/forgetting-makes-you-smarter/

Excerpt:

If, like the rest of us, you wonder why you sometimes forget seemingly easy things, the answer is that there is probably nothing wrong at all.

In fact, a study done by the Neuron Journal suggests that forgetting is actually a natural brain process that might actually even make you smarter at the end of the day.

Good reading for anyone conducting research.  Find it at https://www.insidehighered.com/blogs/rethinking-research/unique-challenges-making-qualitative-research-more-transparent
