The concept of "right-brained" or "left-brained" individuals is considered a widespread myth which oversimplifies the true nature of the brain's cerebral hemispheres (for a recent counter position, though, see below). Proof leading to the "mythbuster" of the left-/right-brained concept is increasing as more and more studies are brought to light.
[n 10] The right middle temporal gyrus, right brainstem, left hippocampus, right cerebellum, right fuisform gyrus, and left lingual gyrus were also activated during fearful stimuli. Activation of multiple brain regions both indicates that emotions are processed in many parts of the brain and that emotions are complex.
Both the left and right hemispheres of the brain have a lateral geniculate nucleus, named after its resemblance to a bent knee (genu is Latin for "knee"). In humans as well as in many other primates, the LGN has layers of magnocellular cells and parvocellular cells that are interleaved with layers of koniocellular cells.
The left hemisphere is usually dominant in right-handed people, although bilateral activations are not uncommon in syntactic processing. It is now accepted that the right hemisphere plays an important role in the processing of suprasegmental acoustic features like prosody , which is "the rhythmic and melodic variations in speech".

There are a number of asymmetries in the human brain including how language is processed mainly in the left hemisphere of the brain. There have been some cases, however, in which individuals have comparable language skills to someone who uses his left hemisphere to process language, yet they mainly use their right or both hemispheres.
Rightward asymmetry can be seen in the right central sulcus (potentially suggesting increased connectivity between motor and somatosensory cortices in the left side of the brain), lateral ventricle, entorhinal cortex, amygdala and temporo-parieto-occipital area. Sex-dependent brain asymmetries are also common. For example, human male brains are ...
Beck: Creativity engages the right hemisphere of the brain, which helps to shift our attention away from left-hemisphere-located anxiety. Instead of crunching us into a tiny prison of fear ...
Functional and structural differences between left and right brain hemispheres can be found in many other vertebrates and also in invertebrates. [ 8 ] It has been proposed that negative, withdrawal-associated emotions are processed predominantly by the right hemisphere, whereas the left hemisphere is largely responsible for processing positive ...
