Brain Patterns Underlying Mothers’ Responses To Infant Cries

In the winter of 1995, scientists pointed the Hubble Telescope at an area of the sky near the Big Dipper, a spot that was dark and out of the way of light pollution from surrounding stars. The location was apparently empty, and the whole endeavor was risky. What, if anything, was going to show up? Over ten consecutive days, the telescope took close to 150 hours of exposure of that same area. And what came back was nothing short of spectacular: an image of over 1,500 distinct galaxies glimmering in a tiny sliver of the universe. 

Now, let’s take a step back to understand the scale of this image. If you were to take a ballpoint pen and hold it at arm’s length in front of the night sky, focusing on its very tip, that is what the Hubble Telescope captured in its first Deep Field image. In other words, those 3,000 galaxies were seen in just a tiny speck of the universe, approximately one two-millionth of the night sky.

So the next time you stand gazing up at the night sky, take a moment to think about the enormity of what is beyond your vision, out in the dark spaces between the stars.

Why do we dream?

In the 3rd millennium BCE, Mesopotamian kings recorded and interpreted their dreams on wax tablets. In the years since, we haven’t paused in our quest to understand why we dream. And while we still don’t have any definitive answers, we have some theories. Here are seven reasons we might dream.

1. In the early 1900’s, Sigmund Freud proposed that while all of our dreams, including our nightmares, are a collection of images from our daily conscious lives, they also have symbolic meanings which relate to the fulfillment of our subconscious wishes.  Freud theorized that everything we remember when we wake up from a dream is a symbolic representation of our unconscious, primitive thoughts, urges and desires. Freud believed that by analyzing those remembered elements, the unconscious content would be revealed to our conscious mind, and psychological issues stemming from its repression could be addressed and resolved.

2. To increase performance on certain mental tasks, sleep is good, but dreaming while sleeping is better.  In 2010, researchers found that subjects were much better at getting through a complex 3D maze if they had napped and dreamed of the maze prior to their second attempt. In fact, they were up to ten times better at it than those who only thought of the maze while awake between attempts, and those who napped but did not dream about the maze. Researchers theorize that certain memory processes can happen only when we are asleep, and our dreams are a signal that these processes are taking place.

3. There are about ten thousand trillion neural connections within the architecture of your brain. They are created by everything you think, and everything you do.  A 1983 neurobiological theory of dreaming, called “reverse learning,” holds that while sleeping, and mainly during REM sleep cycles, your neocortex reviews these neural connections and dumps the unnecessary ones. Without this unlearning process, which results in your dreams, your brain could be overrun by useless connections, and parasitic thoughts could disrupt the necessary thinking you need to do while you’re awake.    

4. The “Continual Activation Theory” proposes that your dreams result from your brain’s need to constantly consolidate and create long term memories in order to function properly. So when external input falls below a certain level, like when you’re asleep, your brain automatically triggers the generation of data from its memory storages, which appear to you in the form of the thoughts and feelings you experience in your dreams. In other words, your dreams might be a random screensaver your brain turns on so it doesn’t completely shut down.   

5. Dreams involving dangerous and threatening situations are very common, and the Primitive Instinct Rehearsal Theory holds that the content of a dream is significant to its purpose.  Whether it’s an anxiety filled night of being chased through the woods by a bear, or fighting off a ninja in a dark alley, these dreams allow you to practice your fight or flight instincts and keep them sharp and dependable, in case you’ll need them in real life. But it doesn’t always have to be unpleasant; for instance, dreams about your attractive neighbor could actually give your reproductive instinct some practice too.

6. Stress neurotransmitters in the brain are much less active during the REM stage of sleep, even during dreams of traumatic experiences, leading some researchers to theorize that one purpose of dreaming is to take the edge off painful experiences to allow for psychological healing. Reviewing traumatic events in your dreams with less mental stress may grant you a clearer perspective and an enhanced ability to process them in psychologically healthy ways. People with certain mood disorders and PTSD often have difficulty sleeping, leading some scientists to believe that lack of dreaming may be a contributing factor to their illnesses.   

7. Unconstrained by reality and the rules of conventional logic, in your dreams your mind can create limitless scenarios to help you grasp problems and formulate solutions that you may not consider while awake. John Steinbeck called it “the Committee of Sleep” and research has demonstrated the effectiveness of dreaming on problem solving. It’s also how renowned chemist August Kekule discovered the structure of the benzene molecule, and it’s the reason that sometimes the best solution for a problem is to “sleep on it”.

And those are just a few of the more prominent theories. As technology increases our capability for understanding the brain, it’s possible that one day we will discover the definitive reason for them; but until that time arrives, we’ll just have to keep on dreaming.

7 Questions to Ask When You’re Feeling Overwhelmed

1. Which of these tasks should I prioritise? Do what’s most important first, and the pressure will subside.

2. Would I achieve more if I got some extra sleep? If you’re too tired to work then you’re usually less productive.

3. Are other people sucking the life out of me? Are there certain individuals who’re demanding too much time?

4. Is there anything at all that I can delegate? Do I have to do it all, or do the whole thing on my own?

5. Have I taken on too much on because “I don’t let people down”, or I’m afraid of saying “no”; or do I fear the negative reactions of others?

6. Is my space full of clutter, and that’s adding to my stress? Do I need to tidy up, or just get rid of some old stuff?

7. Can I withdraw, or take time off to recharge my batteries? Do I really need a break, and need the chance to be refreshed? Would I likely perform better if I made time for self care

Why You Think You Are Not Good Enough AND How to Fix it

“If I asked you to name all the things you love, how long would it take to name yourself.” – Anon

There is no shortage of reasons why we sometimes feel like we flat out aren’t good enough. Maybe it’s low grades in school, or we think we are too thin, or too fat, or too young. Maybe our partner makes us feel inadequate, or our parents seem to believe we can’t do anything right.

Sometimes we do it to ourselves. We compare our home, or clothes, or cars to where someone else lives, or to what they wear, or to what they drive. If we believe their things are better than ours, then we tell ourselves we are less of a person.

Society doesn’t help us believe that we are unique, or that being unique is seriously “good enough.” There is constant pressure to be the best team, the best student, the best assistant, the best employee. We compare ourselves to models in magazines and hold ourselves to a certain standard of perfection that is as unrealistic as it is attainable.

It isn’t a Feeling. It’s a Thought.

When you don’t feel “good enough” it’s often because you are telling yourself you’re stupid, or ugly, or incapable. The thoughts you use to describe yourself make you unhappy. These thoughts make you feel depressed and worthless. According to Ali Miller, MFT, this is an important distinction. She believes that…
