Exogenous Testosterone Enhances Responsiveness to Social Threat in the Neural Circuitry of Social Aggression in Humans
TLDR
Functional magnetic resonance imaging data demonstrate that testosterone enhances responsiveness in neural circuits of social aggression, and it is argued that actions of testosterone on subcortical reactive aggression circuits give rise to this effect.
The brain-computer interface cycle.
TLDR
The aim of this review is to give an overview of the various steps in the BCI cycle, i.e., the loop from the measurement of brain activity, classification of data, feedback to the subject and the effect of feedback on brain activity.
Effects of frequent cannabis use on hippocampal activity during an associative memory task
TLDR
Cannabis users displayed lower activation than non-users in brain regions involved in associative learning, particularly in the (para)hippocampal regions and the right dorsolateral prefrontal cortex, despite normal performance.
Reproducibility of fMRI-Determined Language Lateralization in Individual Subjects
TLDR
The CTA was a robust detector of language-related brain activity, in contrast to the single task approaches, and allowed for reliable calculation of the LI, which was largest when calculated from active voxels in classical language regions.
Function of striatum beyond inhibition and execution of motor responses
TLDR
It is shown for the first time in humans that the striatum becomes more active when the likelihood of inhibiting a planned motor response increases, suggesting that thestriatum is critically involved in inhibitory motor control.
Statistical analysis of functional MRI data in the wavelet domain
TLDR
The proposed method was applied to compare two different fMRI acquisition modalities, and differences of the respective useful signal bandwidths could be clearly demonstrated; the estimated signal, due to the smoothness of the wavelet representation, yielded more compact regions of neuroactivity than standard spatial-domain testing.
Test–retest reliability of fMRI activation during prosaccades and antisaccades
TLDR
Reliability of individual activity maps was largely explained by individual differences in the global temporal signal to noise ratio (SNR), which explained a large portion of the differences between subjects in regional brain activation.
Language lateralization in schizophrenia, an fMRI study
TLDR
The results indicate that language processing is less lateralized in patients than in controls, and postulate that decreased language lateralization in schizophrenia may result from failure to inhibit the right hemisphere.
Functional Anatomical Correlates of Controlled and Automatic Processing
Behavioral studies have shown that consistent practice of a cognitive task can increase the speed of performance and reduce variability of responses and error rate, reflecting a shift from controlled
