The Truth About The Left Brain / Right Brain Relationship : Cosmos And Culture : NPR
Conversely, when left-brain people marry people just like resolved during the first three years of marriage, can lead to divorce, Deckert said. Whereas people with right brain dominance tend to be more emotional, creative, A left brainer is likely to initially notice the facts and features of a date. Sometimes they just have thoughts that come right out, and you're going to have They aren't going to get hung up on defining the relationship with specifics.

In order for people with a TBI to maintain healthy, loving, romantic relationships, they will need support, encouragement, and understanding from their partner. While this sounds like a recipe for the success of any romantic relationship, there are specific ways in which people with brain injury will need to be supported. There are also commitments the people with brain injury will need to make to themselves, their partner, and the relationship, in order to sustain relational happiness and security over the long term.
The partners of people who has a TBI must first educate themselves about how brain injury impacts an individual. In addition to the frequently cited TBI challenges related to thinking such as memory, attention and concentration, and problem-solving, individuals with brain injury often experience changes in behavioral, social, and emotional functioning.

In a relationship, partners often read the emotional and social cues of their partner in order to gauge the stability of the relationship. However, after TBI, some disruption in emotions and challenges with communication are to be expected. Education can also help partners not to personalize behaviors that may be more related to brain injury than a reaction to or reflection of the relationship.
Again, while these may be important skills for any romantic relationship, the way in which a partner de-escalates an argument when their spouse has a TBI will be different from the approach used by couples where brain injury is not a concern. Reading information written for caregivers, attending family member support groups, and meeting with a therapist who has familiarity with brain injury are all solid ways to build an effective skill set.
Of course, maintenance of a healthy relationship always requires the dedication of both partners. People with brain injury can improve the likelihood that their relationship will succeed by attending therapy focused on emotional regulation and compensatory strategy development. Additionally, by focusing on building communication skills, asking for help, and focusing on the positive, survivors can enhance the emotional connection they have with their partner.
So, like other complex skills, the ability to understand what we read or what someone is saying to us requires both hemispheres, working together and separately.

Early studies of hemispheric asymmetries often relied on "split-brain" patients who had the corpus callosum — the bundle of neural fibers that connects the two hemispheres — severed as a treatment for severe epilepsy. In such studies, information could be provided to a single hemisphere at a time by presenting people with input to one side of the visual field, since the right visual field is processed by the left hemisphere, and vice versa.
Your lab uses contemporary neuro-scientific techniques, such as measures of brain wave activity EEG and ERP to investigate hemispheric asymmetries, and typically does so in individuals with intact brains. How do you do so, and do your findings corroborate or challenge earlier inferences made from the behavior of split-brain patients?
We actually use the same basic technique, known as "visual half field presentation. It would make our studies so much easier if it were, since we could just ask people to close one eye!
Instead, half of the information coming into each eye goes to each of the hemispheres, with the result, as you point out, that if you are looking forward, things you see to the right of where you are looking are being picked up initially by your left hemisphere and things to the left by your right hemisphere.
To look at hemispheric differences, we ask our participants, who are usually either college students or retired adults, to look at the center of the screen.
We then display words or pictures, or other types of stimuli fairly rapidly — so people can't move their eyes fast enough to fixate them directly — to the left or the right side of a computer screen.
By comparing how people respond for example, whether they can accurately remember a word when it was processed first by the left hemisphere versus by the right hemisphere, we can test ideas about what each hemisphere is capable of and whether one hemisphere has better, or different, abilities compared to the other. Often, we also measure brain electrical activity in these experiments because that provides rich information about how processing is unfolding over time: In general, the kinds of hemispheric differences that were uncovered in split-brain patients have been replicated and then extended using these techniques in people with intact brains.
This sometimes surprises people, including my fellow cognitive neuroscientists. The idea that the two hemispheres perceive things differently, attach different significance to things, obtain different meanings from stimuli, and, sometimes, make different decisions about what to do seems like it should be an exotic side effect of the split-brain condition. When the hemispheres are connected, don't they just share all the information and operate in a unified fashion?
The answer is, no, they don't. They don't, in part, because they can't. Processing within each hemisphere relies on a rich, dense network of connections. The corpus callosum that connects the hemispheres is big for a fiber tract, but it is tiny compared to the network of connections within each hemisphere.
Physically, then, it doesn't seem feasible for the hemispheres to fully share information or to operate in a fully unified fashion. Moreover, in a lot of cases, keeping things separate is literally!
Dividing up tasks and allowing the hemispheres to work semi-independently and take different approaches to the same problem seems to be a good strategy for the brain It makes sense to have specialized brain regions, just as it makes sense to have divisions of labor in other areas of life. But why have specialized hemispheres? In other words, do you think there's something general that can be said about the sorts of processing that occur in the left hemisphere versus the right hemisphere, or is each simply a constellation of somewhat distinct, specialized regions?
Specifically how and why the hemispheres differ remains a mystery.
They are actually remarkably similar physically, and this is one reason I think that studying hemispheric differences is critical for the field. From this, we hope we can learn something about how and why these anatomical differences matter. However, in doing this, the field has also uncovered a lot of hemispheric asymmetries — cases in which, for example, a left hemisphere brain area becomes active and its right hemisphere homologue with the SAME basic inputs, outputs, etc.
This should really surprise us: There must be physical differences between them, of course — but then, this means that those "subtle" differences are much more critical for function than the field has appreciated. My own view is that studies of hemispheric differences will help to move the field away from thinking in terms of mapping functions onto localized brain areas. I believe that cognitive functions arise from dynamically configured neural networks.
On this view, the role played by any given brain area is different depending on the state of the network of which it is currently a part, and how activity unfolds over time often matters more than where it is in the brain.
Why do the hemispheres differ? I think it is because even small differences in something like the strength with which areas are connected can lead to very different dynamic patterns of activation over time — and thus different functions. For language comprehension in particular, my work has shown that left hemisphere processing is more influenced by what are sometimes called "top-down" connections, which means that the left hemisphere is more likely to predict what word might be coming up next and to have its processing affected by that prediction.
The right hemisphere, instead, shows more "feedforward" processing: Because of what is likely a difference possibly small in the efficacy of particular connections within each hemisphere, the same brain areas in the two interact differently, and this leads to measurable and important asymmetries in how words are perceived, linked to meaning, remembered, and responded to.
This is unlikely to be the only difference between the hemispheres, of course. But I think the answer to your question is that what we see across the pattern of asymmetries is neither a random collection of unrelated differences nor divisions based on one or even a small set of functional principles e. Rather, some of the underlying biology is skewed, and this has far reaching consequences for the kinds of patterns that can be set up over time in the two hemispheres, leading to sets of functional differences that we can hopefully eventually link systematically to these underlying biological causes, and thereby deepen our understanding of how the brain works.
What's surprised you most about the hemispheric asymmetries you've found or failed to find! One of my favorite findings came from an experiment in which we used adjectives to change the meaning of the same noun.
"Left-Brain' vs. "Right-Brain' Opposites Can Attract and Clash
For example, the word "book" in "green book" refers to something concrete — that is, something for which it is easy to create a mental image. However, given "interesting book" people now usually think about the content of the book rather than its physical form, so the same word has become more "abstract" in meaning.
A lot of research shows that concrete and abstract words are processed differently in the brain. We wanted to see if those differences could be found for exactly the same word depending on what it was referring to, and whether the two hemispheres were similarly affected by concreteness. We found in this experiment, as we had previously in many others, that the left hemisphere is very sensitive to the predictability of word combinations.
Fewer nouns can go with "green" than with "interesting," and brain activity elicited in response to "book" reflected this when the words were presented initially to the left hemisphere.
"Left-Brain' vs. "Right-Brain' Opposites Can Attract and Clash
However, to our surprise, it was the right hemisphere that elicited imagery-related brain activity to "green book" compared to "interesting book. Another popular idea is that some people are more "left brained" and others more "right brained.
More generally, what kinds of individual differences do you see in hemispheric specialization? There are certainly individual differences in hemispheric specialization across people, but they are very difficult to reliably determine.
