Dream research has advanced considerably since the discovery of REM sleep. However, despite the progress made and the existence of various theories of dreaming, the neuroanatomical origins underlying dream recall remains a controversial topic. This may have been due to a lack of suitable tools to effectively test such theories. There is now, however, a diverse range of noninvasive brain...
REM sleep is a unique brain state characterized by frontal deactivation alongside activation of the posterior association and limbic cortices. Human brain lesion studies have found that the loss of dreaming is characterized by damage to the frontal and posterior parieto-temporo-occipital association cortex. Therefore, it is reasonable to assume that the function of these brain regions might...
