Your Brain’s Memory Back-Up System

Strong memories involve groups or teams or networks of neurons that fire together.  While neuroscientists have long said that "neurons that fire together wire together," recent reesarch at Cal Tech shows how repeated exposure to something recruits multiple neurons into the memory system, creating built-in redundancy.

It’s Not a Quiz! It’s Retrieval Practice!

Few words stimulate greater anxiety in students than "We're going to have a quiz today."  Most of us can remember that feeling of being unprepared when a pop quiz was announced.  What most of us don't realize, including many teachers, is how important a role quizzes can play in the learning process.

How Neurons Multitask

Duke University researchers have shown that neurons seem to be capable of carrying more than one signal at a time.  They do this, apparently, in much the same way that telecommunications engineers developed rapid switching between pieces of two different messages.

Does Brain Size Matter?

A fascinating article in Cerebrum from the Dana Foundation makes the case that brain size matters by clarifying when and how the size of an animal’s brain makes a difference. 

Pixels the Size of Neurons May Transform Brain Imaging

Technology has been reducing the size of pixels on a screen to the point where scientists believe they can focus on brain activity at the level of individual neurons.  That

The Power of Neuroplasticity

While there has been strong scientific consensus for some time about neuroplasticity, the extent to which our brains can change, at any stage of life, is only starting to become clear.
