Synaptic Sunday #13 – Neuroscience of Gratitude

What is gratitude, and what is its impact on mental and physical health? What systems in the brain are associated with it? How can one cultivate gratitude? Why does it seem to be felt and expressed so much more easily in some people than in others?

Here are some of the ongoing efforts of neuroscientists and psychologists to better understand gratitude:

1) Expanding the Science and Practice of Gratitude

Recently scientists have begun to chart a course of research aimed at understanding gratitude and the circumstances in which it flourishes or diminishes. They’re finding that people who practice gratitude consistently report a host of benefits…

2) The Grateful Brain

3) From the Bottom of My Heart

Put yourself in the position of a Jew during World War II who escapes to France penniless and is forced to beg on the streets. A passerby gives you roasted peanuts — your first morsel of food in several days.

You are allergic to peanuts.

Do you feel grateful? Or bitter, anxious, awkward, sad — perhaps even happy?

Synaptic Sunday #9 – Vivid Memory Edition

1) Why Does a Vivid Memory ‘Feel So Real?’

Researchers found that vivid memory and real perceptual experience share “striking” similarities at the neural level, although they are not “pixel-perfect” brain pattern replications.

and

“Our study has confirmed that complex, multi-featured memory involves a partial reinstatement of the whole pattern of brain activity that is evoked during initial perception of the experience. This helps to explain why vivid memory can feel so real.”

Are vivid memories more accurate than non-vivid memories? Less vulnerable to fabrication and distortion? A memory can feel quite vivid but could be made up in part. Maybe there are certain aspects of a scene that we remember more accurately and other parts that we fill-in, even for a memory that feels like a powerfully accurate recording playing in our minds.

As always, it’s important to distinguish between the accuracy of the memory and the confidence people have in the accuracy of the memory. Are we good judges of how accurately we’ve remembered something?

2) Psychologists Link Emotion to Vividness of Perception and Creation of Vivid Memories

Have you ever wondered why you can remember things from long ago as if they happened yesterday, yet sometimes can’t recall what you ate for dinner last night?
