When looking at short term memory, a portion of it is the active working memory.

One way to look at the active working memory is like matrix multiplication.

Let's say one gets a 5 digit number. It is fairly simple to return that number in the same order as given, which would equate to the identity matrix.

If one had to invert the order of number, then the diagonal of the matrix would be flipped compared to the identity matrix, so equating to a negative determinant.

Now imagine if one had to do more complex calculations like ordering the months of the year alphabetically. Creating a matrix that transposes the months vector is initially not that simple, though once instantiated, it becomes quite simple to repeat.

Depending on how many row alterations are needed, starting from the identity matrix could be a way to quantify the complexity of the task.

The best way to ingest caffeine and far more healthier than energy drinks or soda 👍

"However, the #MRI scans showed that drinking #coffee increased activity in parts of the brain involved in #ShortTermMemory, #attention and #focus, whereas ingesting #caffeine on its own did not."

Brain scans of #CoffeeDrinkers show its effects go beyond caffeine

Brain scans of coffee drinkers suggest there's more to feeling alert than just the caffeine

Coffee and caffeine can have different effects on brain…

Significant short-term memory issues

Interesting and useful twitter thread,
roll-ups not currently working.

3 patients in the last 2 weeks, all with significant short-term memory issues, including forgetting where they are going while driving. No prior dementia. None brought up COVID infection until asked. All three have been infected within the past 4 months when asked. Is anyone else seeing this?
