Brain
There are dozens of other chemical neurotransmitters that are used in more limited areas of the brain, often areas dedicated to a particular function. Serotonin, for example—the primary target of antidepressant drugs and many dietary aids—comes exclusively from a small brainstem area called the raphe nuclei. Norepinephrine, which is involved in arousal, comes exclusively from a nearby small area called the locus coeruleus. Other neurotransmitters such as acetylcholine and dopamine have multiple sources in the brain, but are not as ubiquitously distributed as glutamate and GABA.
Educational neuroscience
The term "neuromyths" was first coined by an OECD report on understanding the brain. The term refers to the translation of scientific findings into misinformation regarding education. The OECD report highlights three neuromyths for special attention, although several others have been identified by researchers such as Usha Goswami.The idea that the two hemispheres of the brain may learn differently has virtually no grounding in neuroscience research. The idea has arisen from the knowledge that some cognitive skills appear differentially localised to a specific hemisphere (e.g., language functions are typically supported by left hemisphere brain regions in healthy right handed people). However, massive amount of fibre connections link the two hemispheres of the brain in neurologically healthy individuals. Every cognitive skill that has been investigated using neuroimaging to date employs a network of brain regions spread across both cerebral hemispheres, including language and reading, and thus no evidence exists for any type of learning that is specific to one side of the brain.
