Understanding Dyscalculia and How the Brain Processes Numbers

Understanding-Dyscalculia-How-the-Brain-Processes-Numbers

Dyscalculia is a learning disability, which is sometimes called number blindness, and similar to dyslexia, but for numbers. Researchers estimate that as much as 7% of the population has dyscalculia, which can be marked by severe difficulties in dealing with numbers despite otherwise normal intelligence.

Scientists have shown, using imaging tests, that fructose can trigger brain changes that lead to overeating. They found that after drinking a fructose beverage, the brain doesn’t register the fullness feeling as it does when simple glucose is consumed.

The enzyme protein kinase M-ζ (PKM-ζ) was thought to be a fixture of long-term memory, as its inhibition could erase old memories, whilst adding it could strengthen faded ones. Two independent groups have challenged the role of this memory molecule by developing mice that completely lack it and show no detectable memory problems.

Darcin in Mice Urine Attracts Other Mice

Darcin in Mice Urine Attracts Other Mice Repeatedly

Mice seem to be addicted to the scent of urine and repeatedly go back to spots where they found the excretions. Researchers have discovered that this behavior is triggered by a single protein in the urine of male mice.
