What does the research tell us about each hemispheres ability to function independently (e.g., cognitively, creatively, etc.) and in unison? What are the implications for the cognitive neuroscientist in terms of research?
Even though a variability of neurochemical and neuroanatomical sections are involved in the preparation of memory, functional specialization significantly regulates what kind of material can be learned or even documented by each half of the cerebrum. This is for the reason that the code or form in which a stimulus is signified in the brain and memory is mainly controlled by the way in which it is treated and the alterations that take place. For the reason that the right and left cerebral hemispheres differentially route material, the method in which this information is represented also will be lateralized (Bradshaw & Mattingly, 1997). Hence, some types of information only can be processed or stored by the right vs. the left cerebrum.
For example, it is well known that the left hemisphere is responsible for the encoding and recall of verbal memories, whereas the right cerebrum is dominant in regard to visual-spatial, non-verbal, and emotional memory functioning (Joseph 1982, 1988a, 1990a,b, 1992, 1993, 1996, 2003). If the left temporal lobe were destroyed, verbal memory functioning would become impaired since the right cerebrum does not readily store this type of…
