H. What is the function of the third ventricle, fourth ventricle, cerebellum and brain stem?
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
Since it is close structurally to the hippocampus, the amygdala is involved in controlling memory consolidation, especially emotional memories; when a memory is emotionally charged, it has a better retention rate than one that is not. The hippocampus is generally seen as having an essential role in the creation of new memories about past experiences; it's even responsible for memories that can be verbalized also known as declarative memory. Damage to it result in difficulties in forming new memories and being able to access new memories formed before the
Marsha is a single mother of three, the youngest being in high school. She works as a sales associate in the women’s fashion section of a larger department store. Last year, Marsha experienced a cerebral vascular accident, or stroke, while on her way to work and was brought in to the hospital. Strokes occur when the blood supply of the brain is disrupted, such as an ischemic attack, thrombosis, or a ruptured blood vessel. When the patient awoke in the hospital, she was unable to understand the staff or her family and expressed difficulty in forming replies. This suggests that the CVA may have occurred in the left hemisphere of the brain, specifically in the Broca and Wernicke’s areas. The medical team suggested that Marsha be released from
Visual fields full to confrontation. Extraocular muscles intact. PERRLADC. Normal facial symmetry, sensation, and movement. Tongue and uvula were midline. Decreased auditory acuity bilaterally. Normal shoulder shrug.
The results of this study show us the brain is not in fact symmetrical and the two hemispheres in the brain work in different ways. The left hemisphere is known to play the dominant role, which is in control of all complex behavioural and cognitive processes as for the right hemisphere it only plays a minor role. This report will further analyse how different the two hemisphers is the dominant side of the brain.
