The Brain and Emotional Intelligence: New Insights

February 24, 2019

The title of this post is identical to the title of another book by Daniel Goleman. The previous book on which many healthy memory blog posts were based was “Emotional Intelligence.” Emotional intelligence is by far our most important intelligence. Dr. Goleman writes, “In this book I want to provide new updates, sharing with you some key findings that further inform our understanding of emotional intelligence and how to apply this skill set.”

There is a brain basis for emotional intelligence. This comes from neural imaging and lesion studies. Neural imaging allows the identification of where the activity in the brain is occurring. Lesion studies are from injuries or surgeries done on parts of the brain to see what functions are lost.

The right amygdala (there are two, one in each brain hemisphere) is a neural hub for emotion located in the midbrain. Patients with lesions or other injuries to the right amygdala showed a loss of emotional self-awareness—the ability to be aware of an understand our own feelings.

Another area crucial for emotional intelligence is also in the right side of the brain. It’s the right somatosensory cortex; injury here also creates a deficiency in self awareness, as well as empathy, the awareness of emotion in other people. The ability to understand and feel our emotion is critical for understanding and empathizing with the emotions of others. Empathy also depends on another structure in the right hemisphere, the insula, that senses our entire bodily state and tells us how we’re feeling. Tuning in to how we’re feeling ourselves plays a central role in how sense and understand what some else is feeling.

Another critical area is the anterior cingulate, which is located at the front of a band of nerve fibers that surround the corpus callosum, which ties together the two halves of the brain. The anterior cingulate is an area that manages impulse control, which is the ability to handle to handle our emotions, particularly distressing emotions and strong feelings.

Finally, there is the ventral medial strip of the prefrontal cortex. The prefrontal cortex is just behind the forehead, and is the last part of the brain to become fully grown. This is the brain’s executive center; the abilities of solve personal and interpersonal problems, to manage our impulses, to express our feelings effectively and to relate well to others resides here.

When writing this HM wondered if deficiencies in these areas might, in part, explain Trump’s bullying, callous, and impulsive behavior. Perhaps such deficiencies might also explain his difficulties in keeping and recruiting staff.

Goleman’s Model of Emotional Intelligence has the following four generic domains: self-awareness, self-management, social awareness and relationship management. Self awareness plays into both social awareness and self management. Social awareness and self management play into relationship management. And it is relationship management that has a positive impact on others.

UNTHINKABLE

The title of this post is identical to the title of a book by Helen Thomson. The subtitle is “An Extraordinary Journey Through the World’s Strangest Brains.” In the opening chapter Ms. Thomson provides an overview of the brain. The most recognizable region of the human brain is the cerebral cortex. It forms the outside shell and is divided into two almost identical hemispheres. Each side of the cortex is divided into four lobes, which together are responsible for all our most impressive mental functions. If you touch your forehead, the lobe closest to your finger is called the frontal cortex and it allows us to make decisions, controls our emotions and helps us understand the actions of others. It gives us all sorts of aspects of our personality; our ambition, our foresight and our moral standards.

If you were to trace your finger around either side of your head toward your ear, you would find the temporal lobe, which helps us understand the meaning of words and speech and gives us the ability to recognize people’s faces.

Run you finger up toward the crown of your ear and you’ll reach the parietal lobe, which is involved in many of our senses, as well as certain aspects of language.

Low down toward the nape of the neck is the occipital lobe, whose primary concern is vision.

Hanging of the back of the brain we have a second “little brain,” a distinctive cauliflower-shaped mass. This is the cerebellum and it is vital for our balance, movement and posture. The vast majority of the cerebellum connects to regions of the cortex that are involved in cognition, perception, language and emotional processing.
A review of maps of the cerebellum built from functional MRI brain scans confirmed that all major cortical regions have loops of connections running to and from the cerebellum. The cerebellum has conversations with different areas of the cortex: taking information from them, transforming it and sending it back to where it came from. One of the more unexpected connections was with the prefrontal cortex, which lies far from the cerebellum at the front of the brain and has long been considered the most advanced part of the brain. This region is in charge of abilities such as planning, impulse control, and emotional intelligence. It is disproportionately large and complex in humans compared with our closest species. To learn more about the cerebellum see the healthy memory blog post “The Brain’s Secret Powerhouse That Makes Us Who We Are.”

If you were to pry open the two hemispheres, you would find the brain stem, the area that controls each breath and every heartbeat, as well as the thalamus, which acts as a grand central station, relaying information back and forth between all the other regions.
The brain is full of cells called neurons which are too small to be see with the naked eye. These cells pass messages from one side of the brain to the other in the form of electrical impulses. Neurons branch out forming connections with its neighbors. If you were to count one of these connections every second, it would take you three million years to finish.

Ms. Thomson writes, “We now know the mind arises from the precise physical state of these neurons at any one moment. It is from this chaotic activity that our emotions appear, our personalities are formed. and our imaginations are stirred. It is arguably one of the most impressive and complex phenomena known to man.

So it’s not surprising that sometimes it al goes wrong.”
