RATIONALE: Abdominal aortic aneurysms (AAAs) are mostly asymptomatic. If aortic aneurysms become symptomatic, complications include peripheral embolization, acute aortic occlusion, and aortic rupture. However, there are also unusual complications caused by aortic aneurysms. PATIENT CONCERNS: An 87-old male with dabigatran therapy presented with newly developed melena and acute renal failure. Radiological imaging revealed an AAA with thrombotic and calcified deposits which affected the renal arteries...

Turning has been implicated as a complex task that requires both motor and cognitive resources. Accumulating evidence shows that patients with Parkinson's disease (PD) require more steps and more time to complete a turn, however, the role of the prefrontal cortex during turning is not clear. Forty nine patients with PD without freezing of gait (mean age 71.7 ± 1.0 years; 67% men, disease duration 9.7 ± 1.3 years) performed motor and cognitive tests. Prefrontal activation, specifically in Brodmann area 10 (BA10), during turning and usual walking was measured using functional near infrared spectroscopy (fNIRS)...

Brodmann areas 44 and 45 are known as Broca's area; however, their true functional roles are still unknown. Recent developments in neuroimaging techniques revealed the structures and functions of Broca's area in detail. More specifically regarding language functions, sufficient evidence has been accumulated that this region subserves the center of syntactic processing, not necessarily motor functions. Here, we review a role of Broca's area as the grammar center, including other roles in nonlinguistic functions...

So Fujimoto, Yutaka Komura
Brodmann areas 41 and 42 are located in the superior temporal gyrus and regarded as auditory cortices. The fundamental function in audition is frequency analysis; however, the findings on tonotopy maps of the human auditory cortex were not unified until recently when they were compared to the findings on inputs and outputs of the monkey auditory cortex. The auditory cortex shows plasticity after conditioned learning and surgery of cochlear implant. It is also involved in speech perception, music appreciation, and auditory hallucination in schizophrenia through interactions with other brain areas, such as the thalamus, frontal cortex, and limbic systems...

The anatomy and function of the angular gyrus (Brodmann Area 39) and supramarginal gyrus (Brodmann Area 40) are described here. Both gyri constitute the inferior part of the parietal lobe. Association fibers from the angular gyrus project to the dorsolateral prefrontal cortex via the superior longitudinal fasciculus (SLF) II/arcuate fasciculus (AF), whereas those from the supramarginal gyrus project to the ventrolateral prefrontal cortex via SLF III/AF. Damage to the left angular gyrus causes kanji agraphia (lexical agraphia) and mild anomia, whereas damage to the left supramarginal gyrus causes kana alexia (phonological dyslexia) and kana agraphia (phonological agraphia)...

First, Brodmann areas 27, 28, 36 and 37, were anatomically defined in the beginning of this review. These areas exist in the parahippocampal or fusiform gyrus of the ventral temporal lobe in humans. Subsequently, the current understanding of their functions was summarized on the basis of recent findings mainly through human functional neuroimaging studies and animal studies. Rodent studies have shown the existence of neuronal activities for representing space, such as those involving head-direction cells or grid cells, in areas 27 (the parasubicular cortex) and 28 (the ventral entorhinal cortex)...

The limbic lobe defined by Broca is a cortical region with highly diverse structure and functions, and comprises the paleo-, archi-, and neocortices as well as their transitional zones. In the limbic lobe, Brodmann designated areas 27, 28, 34, 35, and 36 adjacent to the hippocampus, and areas 23, 24, 25, 26, 29, 30, 31, 32, and 33 around the corpus callosum. In the current literature, areas 27 and 28 correspond to the presubiculum and entorhinal cortex, respectively. Area 34 represents the cortico-medial part of the amygdaloid complex...

The posterior cingulate cortex (Brodmann area, BA 23) is the hub of the default mode network (DMN). Moreover, its network connectivity decreases early in Alzheimer disease. The anterior cingulate cortex (BA 24) is connected to networks such as the DMN, working memory network (WMN), and salience network (SN) and plays a role in network coordination. The subgenual anterior cingulate cortex (sgACC) on the rostral region of the anterior cingulated cortex is suggested to be associated with depression.

The 20, 21, and 22 areas in the temporal lobe as classified by Brodmann are almost identical with Economo and Koskinas's TA, TE1, and TE2, and, generally, with the gyrus, middle temporal gyrus, and inferior temporal gyrus according to brain anatomy. Before Brodmann's classification, Flechsig published his book "Soul and Brain" in 1897, in which primary, secondary, and association areas in the brain were classified. More recently, results from research using magnetic resonance imaging (MRI) and fMRI support the parcellation of the cerebral cortex proposed by Flechsig, Brodmann, and Economo more than one century ago...

Brodmann areas 17, 18, and 19 in the human brain are visual cortices of the occipital lobe. Each area has its own retinotopic representations, particulary area 19, which has many small retinotopic areas representing half or all of the contralateral visual field, several functional areas, and nine cytoarchitectonic areas. Several fasciculi are known as occipital fiber connections, but their precise endpoints are not clear. Lesions in the visual cortices cause several visual disorders including visual field defect, visual hallucinations, metamorphopsia, and different kinds of visual agnosia...

It is well known that the insular cortex (Brodmann areas 13, 14, 15, and 16) located deep inside the Sylvian fissure is associated with mental functions such as perception, language, cognition, affect, and movement. In particular, the insular cortex has been linked to interoception, which is the representation of bodily physiological states that is used to regulate bodily states and mental functions. Recently, a common principle to explain such functions of the insular cortex has been proposed. The principle posits that the anterior insula generates predictions of future bodily states, computes the error by comparing the prediction with the actual sensory signals, and integrates the body with the mind by minimizing the prediction error...

Broadman area 12, together with area 11, is located in the orbitofrontal area. A voxel-based morphometric (VBM) study revealed the association between bilateral brodmann areas 12/47 and taste disturbance in individuals with frontotemporal lobar degeneration (FTLD). In our VBM study in patients with Parkinson's disease, decision-making impairments were associated with atrophy of the bilateral Brodmann area 12, indicating that this area may play an important role in social cognitive function. Our recent study also demonstrated that this area may serve as time order judgement or mental time travel...

Brodmann area 11 is one of the main constituent of the orbitofrontal cortex, and area 46 is that of the dorsolateral prefrontal cortex. The main function of Brodmann area 11 is the processing of emotion and value, whereas the main function of Brodmann area 46 is the processing of cognitive information, including working memory. In comparison, the function of area 47 is more complex. This area is related to the feeling of empathy towards the story contents of others, which is thought to be the emotional aspect of this area, while this area is also activated during automated action...

This paper reviews the structural specificities and functional roles in Brodmann areas 10 and 38. A number of studies have focused on both areas through various approaches including neuropsychology, neuroimaging, psychiatry, neurology, and neurosurgery. Both areas 10 and 38 may have a substantially very complex higher-order cognitive functions, which are quite hard to disentangle. Here, I picked up some fundamental perspectives for reviewing previous studies, to provide efficient research orientations for the elucidation of functions in both areas...

Based on cytoarchitectonic analyses, Brodmann assigned numbers 8 and 9 to certain areas of the dorsal and medial prefrontal cortex (PFC) in humans and monkeys. Petrides and Pandya re-analyzed the cytoarchitectures of the human and monkey PFCs, and proposed slightly different brain maps for both species. They assigned numbers 8, 9 and 9/46 to the areas that were originally named areas 8 and 9. Areas 8 and 9 have both lateral and medial regions respectively. The lateral area 8 is important for conditional discrimination learning...

Areas 5 and 7 are the association cortices which are located in the parietal lobe and process somatosensory and visual information, respectively. The location of area 7 differ in the Brodmann's human and monkey brain map, in the human brain map area 7 is located in the superior parietal lobe, while it is in the inferior parietal lobe in the monkey brain map. Thus, it is difficult to discuss the function of these areas.

The primary motor cortex is located in Brodmann area 4 at the most posterior part of the frontal lobe. The primary motor cortex corresponds to an output stage of motor signals, sending motor commands to the brain stem and spinal cord. Brodmann area 6 is rostral to Brodmann area 4, where multiple higher-order motor areas are located. The premotor area, which is located in the lateral part, is involved in planning and executing action based on sensory signals. The premotor area contributes to the reaching for and grasping of an object to achieve a behavioral goal...

A brief history of cytoarchitectonic studies of Brodmann areas 3, 1, and 2 is presented here. Results of neurophysiological studies, i.e., recordings of single neuronal activities in these three cytoarchitectonic areas of the monkey brain are described and interpreted on the basis of a hierarchial schema model of information processing. Finally, recent studies on the human postcentral gyrus are reviewed and compared with the results of the aforementioned monkey studies.

Brodmann's map is one of the best known maps of the human cerebral cortex. However, Korbinian Brodmann's 1909 monograph, containing the first map, has not been widely read by neurologists. Following the publication of the first map, Brodmann reproduced the map in 1910, and again in 1914, with several important differences. The latter map is also characterized by the exclusion of Brodmann area numbers, "12-16, and 48-51;" contrastingry numbers "1-52" have been described in the animal brain. Here, we provide a detailed explanation of the versions of Brodmann's maps, and review his academic profile and works...

Background -Numerous studies have reported favorable outcomes using drug-coated balloons (DCBs) for treatment of symptomatic peripheral artery disease (PAD) of the superficial femoral and popliteal arteries. However, the treatment effect compared to an uncoated balloon has differed greatly amongst the randomized trials with better outcomes observed with higher-dose DCBs. This European trial was designed to assess the safety and effectiveness of a next-generation low dose (2 µg/mm(2) surface dose of paclitaxel) DCB...
