This damage can be seen on neuroimaging scans. [5] Frontal lobe damage becomes the most prominent as alcoholics age and can lead to impaired neuropsychological performance in areas such as problem solving, good judgment, and goal-directed behaviors. [3] Impaired emotional processing results from damage to the limbic system.
The limbic lobe is an arc-shaped cortical region of the limbic system, on the medial surface of each cerebral hemisphere of the mammalian brain, consisting of parts of the frontal, parietal and temporal lobes.
The limbic system is a term that was introduced in 1949 by the American physician and neuroscientist, Paul D. MacLean. [34] [35] The French physician Paul Broca first called this part of the brain le grand lobe limbique in 1878. [6] He examined the differentiation between deeply recessed cortical tissue and underlying, subcortical nuclei. [36]
Damage to the limbic system involves loss or damage to memory, and may include: [citation needed] loss or confusion of long-term memory prior to focal neuropathy (retrograde amnesia) inability to form new memories (anterograde amnesia) loss of, or reduced emotions ; loss of olfactory functions; loss of decision-making ability
Posterior association area: Located in the posterior parietal lobe. [6] This area plays an important role in perception and language. Damage to this area can result in agnosia. Limbic association area: Located in the anterior-ventral portion of the temporal lobe, this area links emotion with sensory inputs. [7]
The Papez circuit / p eɪ p z /, [1] [2] [unreliable source?] [3] or medial limbic circuit, is a neural circuit for the control of emotional expression. In 1937, James Papez proposed that the circuit connecting the hypothalamus to the limbic lobe was the basis for emotional experiences.
The uncinate fasciculus is a bi-directional pathway between the temporal lobe and frontal lobe; it is traditionally considered to be part of the limbic system. [2] It has been proposed that the uncinate fasciculus allows mnemonic representations stored in the temporal lobe to interact with and guide decision making in the frontal lobe. [4]
This is the upper part of the "limbic lobe". The cingulate cortex is made up of an area around the midline of the brain. Surrounding areas include the retrosplenial cortex and the precuneus. Cytoarchitectonically the posterior cingulate cortex is associated with Brodmann areas 23 and 31.
