BACKGROUND: Synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome is a rare disease and there is no related literature concerning psychiatric symptoms in SAPHO patients. Thus, we believe that this will be the first paper to explore the episode and the neurobiological basis of depression symptoms in SAPHO patients using resting state functional magnetic resonance imaging (rs-fMRI). Twenty-eight SAPHO patients and fifteen age- and gender- matched normal controls (NC) were consecutively submitted to psychiatric evaluation and rs-fMRI scanning...

[Purpose] The purpose of this study is to assess the influence of tool holding on brain activities during motor imagery in two tasks: imagining the movement of writing the alphabet while holding a pen and without holding the pen. [Subjects and Methods] Eleven healthy right-handed adults performed two tasks, holding a pen and not holding the pen during imagining the movement of writing the alphabet using a pen. Regions of targets were Brodmann areas 6 which were a motor-related region, 44/45 and 39/40 which taken on the role of forming the body schema...

Suicide is a serious public health problem. In this study, we investigated functional brain changes to novel visual stimuli of suicidal means, DNA methylation status, and the relationship between the two markers. 14 suicidal attempt patients (SAs) and 22 healthy controls were included. Pictures of facial expressions and suicidal means were shown to subjects during fMRI scanning. 11 CpG sites within transcription factor binding site of CACNA1C gene were selected. In knives (K) vs. natural landscape (NL) condition, left middle frontal gyrus (Brodmann's area, BA 6 and 46) and left inferior frontal gyrus (BA 9) were shown to be significantly higher brain activation in the SAs than the controls (p<0...

OBJECTIVE: In electroencephalography (EEG)-based brain-computer interface (BCI) systems for motor control tasks the conventional practice is to decode motor intentions by using scalp EEG. However, scalp EEG only reveals certain limited information about the complex tasks of movement with a higher degree of freedom. Therefore, our objective is to investigate the effectiveness of source-space EEG in extracting relevant features that discriminate arm movement in multiple directions. APPROACH: We have proposed a novel feature extraction algorithm based on supervised factor analysis that models the data from source-space EEG...

Knowledge of the encephalon anatomy is crucial for neurosurgical practice, especially the main cortical functional structures and their connections. General organisation of the encephalon is presented with frontal, parietal, occipital, temporal, limbic and insular lobes and their Brodmann correspondence. Secondly, subcortical anatomy will be presented with main white matter fasciculi in three separated categories: association, commissural and projection fibers. Main association fibers are inferior occipitofrontal fasciculus, superior longitudinal fasciculus, arcuate fasciculus, inferior longitudinal fasciculus, uncinate fasciculus, and cingulum...

The oviductal epithelium is crucial for the integrity of the female organ. Previously we got evidence that the surface proteome of oviductal epithelial cells (Oecs) is promptly altered in response to insemination and thus suggested that this early phase plays a notable regulatory role in maintaining cellular function. This study further aimed to assess the effect of semen on the cellular and molecular mechanisms in rabbit Oecs. A quantitative gel-based proteomic approach was applied to analyze changes at three time points (0h, 1h, 2h) after intrauterine insemination (IUI) compared to time matched controls...

Immune function abnormalities have been implicated in the pathophysiology of schizophrenia (SZ). This is primarily based on the observation that the levels of proinflammatory cytokines are significantly increased in the serum of SZ patients compared with normal control (NC) subjects. However, it is not known if similar cytokines abnormalities are also present in the brain of SZ patients. To further examine the involvement of inflammatory cytokines in the brain of SZ patients, we determined the protein and mRNA levels of TNF-α, IL-1β, IL-2, IL-6, IL-8, IL-10, IL-13, LTA and IL-1RA in the prefrontal cortex (PFC, Brodmann area 9) of SZ patients...

Alzheimer's disease is the most common neurodegenerative disease of Western societies, suggesting the need for early diagnosis, even in preclinical stages. In this vein, the localization of neuronal generators of event-related potential (ERP) components, that is, the mismatch negativity and the P300, based on high-density electroencephalogram data, was explored as a means to enhance their sensitivity as markers of preclinical Alzheimer's disease (AD). A 2-tone oddball experiment was conducted, involving 21 healthy elderly, 21 mild cognitive impairment, and 21 mild AD patients, while high-density electroencephalogram data were recorded...

Progressive loss of gray matter has been demonstrated over the early course of schizophrenia. Identification of an association between cognition and gray matter may lead to development of early interventions directed at preserving gray matter volume and cognitive ability. The present study evaluated the association between gray matter using voxel-based morphometry (VBM) and cognitive testing in a sample of 16 patients with first-episode psychosis. A simple regression was applied to investigate the association between gray matter at baseline and 80 months and cognitive tests at baseline...

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...
