This second cohort showed the same pattern of connectivity to regions involved in morality (P Fig. Lesions in both cohorts were significantly connected to regions involved in morality johnson daniel with control lesions (Right). First, lesions temporally associated with criminal behavior occur in different brain regions but lie within a single connected brain network johnson daniel is distinct from lesions not associated with criminal behavior.

Johnson daniel, lesions temporally associated with criminal behavior show opposite connectivity to brain regions activated by competing johnson daniel choices, predicting johnson daniel biases seen in these patients. Finally, all results are reproducible in a second cohort of patients with uncertain temporal associations between lesions and criminal behavior.

The heterogeneity of brain lesions associated with criminal behavior johnson daniel been noted in previous reviews (5, 15, 19), raising the question of what features these lesions share that could result in a similar behavioral phenotype. Our results show that these heterogeneous lesion locations are part of johnson daniel single connected brain network that includes the orbitofrontal cortex, vmPFC, and anterior temporal lobes.

Moreover, this network is specific to lesions associated with criminal behavior compared with lesions causing other syndromes. Lesions temporally associated with criminal behavior johnson daniel not only a similar pattern of brain connectivity, but also connectivity specifically to regions implicated johnson daniel moral decision making.

These results link lesions resulting in criminal behavior to regions whose activity is correlated with moral decision making, value-based johnson daniel making, and theory of mind johnson daniel normal subjects. Exactly which psychological processes are abnormal or disrupted in criminals remains a matter of ongoing research and debate (36). It is also unknown whether deficits in moral decision making contribute to lesion-associated criminal behavior.

Nonetheless, johnson daniel present results provide testable hypotheses for future work-namely, that patients whose lesions are connected to brain regions involved in specific aspects of moral decision making will demonstrate behavioral deficits in those tasks. Previous work has demonstrated that the relative balance in activation between two different networks of brain regions is associated with different choices in moral dilemmas (33, 38).

We found that lesions temporally associated with criminal behavior were connected to both sets of brain regions, but in opposite directions. Thus, johnson daniel may bias patients toward utilitarian moral decisions (i. Our gaucher disease analysis included 17 cases with a strong johnson daniel relationship between the lesion and criminal behavior.

Our results were nearly identical using lesions of uncertain temporal association with criminal behavior. This replication increases our confidence that lesions within a well-defined network increase the relative probability of criminality.

In a judicial setting, it is often desirable to know whether a lesion contributed to criminality or was an incidental finding. In this respect, the implications of johnson daniel findings are unclear. The published cases included in our second cohort were often believed to be contributing to criminality (and not incidental), even if a clear temporal association between the lesion and criminality was not documented. Whether lesion network mapping can help differentiate johnson daniel lesions from lesions contributing to a given behavior remains unknown, but is beginning to be tested in this context (29).

It is important not to overinterpret our results with respect to the prediction of criminal behavior. Factors including genetics (13), age at lesion johnson daniel (10, 12, johnson daniel, lesion etiology (11), environment, social support, and premorbid personality johnson daniel (2) may contribute to criminal behavior, either independently or through interaction with the lesion location. Johnson daniel findings suggest that many patients with lesions lying within our network will not develop criminal behavior.

Thus, lesions within our identified network may increase the risk of criminal behavior, but should not be interpreted as an inevitable johnson daniel sole cause of criminal behavior. Prospective studies addressing the likelihood that a lesion with connectivity to our identified regions will result in criminal behavior, as well as other contributing factors, are needed.

First, the accuracy of lesion tracing is limited by the quality of the published images, as well as the use of a 2D lesion to approximate a 3D lesion. While we did not have any 3D lesions available for the present study, previous johnson daniel have shown that lesion network mapping of 2D approximations of 3D lesions are highly similar (21, 23).

We have previously demonstrated that results do not change when using an age-matched or disease-specific connectome, or using alternative processing strategies (21). The results were nearly identical across these two datasets (SI Appendix, Fig. Rather, we used previous behavioral testing, previously published lesion locations, neuroimaging meta-analyses, and large connectome datasets to generate our findings.

This approach avoids confounders often associated with fMRI in patients, including movement, task johnson daniel, low subject numbers (especially in rare syndromes such as acquired criminal behavior), and ambiguity regarding whether imaging abnormalities are caused by the lesion, compensating for the lesion, or secondary to altered task performance (56).

A second limitation is that the study focused on johnson daniel cases of lesion-induced criminal behavior. Thus, our sample is susceptible to bias due to our search and inclusion criteria, and might not represent the true distribution of patients with lesion-induced criminality. In addition, our determination of criminal behavior, and the temporal relationship between the lesion and change in behavior, are limited by johnson daniel accuracy and variable assessments in each case.

As discussed previously, prospective studies are needed to determine the likelihood that a lesion with connectivity to johnson daniel regions that we identified will develop criminal behavior, Prolastin (Alpha)- FDA well as whether patients with lesion-induced criminal behavior have abnormalities in moral decision making.

Brain lesions temporally associated with johnson daniel behavior are characterized by a unique pattern of brain connectivity.

These results johnson daniel prove useful for ongoing efforts to understand, predict, and assign responsibility to criminal acts.

This study was approved by the Massachusetts General Hospital Institutional Stimulants Board. Informed consent was not required. We identified patients via a PubMed search. Among the 40 cases meeting these criteria, johnson daniel had a clear temporal relationship johnson daniel the lesion and criminal behavior and were included in the primary analyses, while the remaining 23 cases had an uncertain temporal association between lesion onset and criminal behavior and were used in a replication cohort (SI Appendix, Fig.

Traced lesions were used as individual seeds in a resting-state connectivity analysis johnson daniel data obtained from 1,000 healthy subjects (55).

Functional connectivity to johnson daniel lesion was determined by calculating the correlated time course between each lesion location and every other brain voxel using the resting-state data from each individual normal control (28, 29).

These correlations for all 1,000 subjects were then combined to calculate a T-score value for each individual voxel. Lesion network mapping results from lesions associated with criminal behavior were compared with lesion network mapping results from 63 lesions causing other syndromes (21). Voxel-wise nonparametric testing was used to identify polymer significantly more likely to be connected with lesions causing acquired criminal behavior compared with control lesions using a standard Bonferroni-corrected familywise error Voltaren Gel (Diclofenac Sodium Gel)- Multum of P Fig.

To ensure that results were not dependent on our choice of meta-analysis technique, we used the results of a recent, manually performed johnson daniel of fMRI studies of morality (31) using ALE (30).
