Example sentences for: prefrontal
How can you use “prefrontal” in a sentence? Here are some example sentences to help you improve your vocabulary:
Executive function tasks activate frontal areas such as the anterior cingulate cortex and lateral prefrontal cortex, an area for which certain anatomical aspects have been shown to be highly heritable [ 23 ] . Recently, we described the Attention Network Test (ANT) that measures the efficiency of these three major neural networks [ 24 ] . The ANT is advantageous for genetic studies, insofar as it distinguishes between separate functions of attention (alerting, orienting and executive) that are correlated with the activation of these specific neuroanatomical circuits.
In discussing their findings, the authors suggest that their study supports previous work indicating that the prefrontal cortex is a candidate region for integration of the sensory and emotional aspects of tinnitus.
Studies showing the expression of dopamine receptors in the anterior cingulate cortex [ 26 ] and that activation of mesocortical dopaminergic neurons via apomorphine enhances activity in the prefrontal cortex [ 27 28 ] suggest that dopaminergic modulation influences the efficiency of the executive attention network.
A recent finding showed that COMT genotype was related to performance on the Wisconsin Card Sorting Test of executive cognition [ 55 ] . In addition, those subjects with the Methionine alleles needed less prefrontal cortical activity, as judged by fMRI, to show the same level of performance on the N-back task.
Studies of alert monkeys suggest that the effectiveness of alerting produced by a warning signal can be eliminated by drugs that block noradrenaline [ 7 ] . Lesions of the cholinergic system [ 8 ] and of drugs blocking ACh transmission have effects on orienting of visual attention in monkeys [ 9 ] . The executive network involves dopamine rich areas of the prefrontal cortex and anterior cingulate.
