Remembering. Electricity. Not asking the right questions.
Direct electrical stimulation of the human amygdala, a region of the brain known to regulate memory and emotional behaviors, can enhance next-day recognition of images when applied immediately after the images are viewed, neuroscientists have found. The results were published in PNAS. The findings are the first example of electrical brain stimulation in humans giving…

Remembering… (for no reason at all)
Recalling the names of old classmates 50 years after graduation or of favorite childhood television series illustrates the amazing abilities of human memory. Emotion and repeated exposure are both known to play a role in long-term memorization, but why do we remember things that are not emotionally charged and have only been seen or experienced…

Forgetting. Thus, being able to think.
Even as the power of our modern computers grows exponentially, biological systems - like our brains - remain the ultimate learning machines. By finding materials that act in ways similar to the mechanisms that biology uses to retain and process information, scientists hope to find clues to help us build smarter computers. Inspired by human…

Sleeping. Unlearning. Room to grow…
Sleep research high-resolution images show how the brain resets during sleep: Striking electron microscope pictures from inside the brains of mice suggest what happens in our own brain every day: Our synapses (the junctions between nerve cells) grow strong and large during the stimulation of daytime, then shrink by nearly 20 percent while we sleep,…

Stop remembering. To remember…
A new study has shown how intentional recall is beyond a simple reawakening of a memory; and actually leads us to forget other competing experiences that interfere with retrieval. Quite simply, the very act of remembering may be one of the major reasons why we forget. (1) Stop trying to remember. And you will…
