Measuring cognitive flexibility: A brief review of neuropsychological, self-report, and neuroscientific approaches Front Hum Neurosci (IF 2.9) Pub Date : 2024-02-19 Kelly Hohl, Sanda Dolcos
Cognitive flexibility involves dynamic processes that allow adaptation of our thinking and behavior in response to changing contextual demands. Despite a large consensus about its beneficial effects, cognitive flexibility is still poorly understood. In this mini review, we examined the main conceptualizations and approaches for assessing cognitive flexibility: (1) neuropsychological tasks, (2) self-report

DiMANI: diffusion MRI for anatomical nuclei imaging—Application for the direct visualization of thalamic subnuclei Front Hum Neurosci (IF 2.9) Pub Date : 2024-02-19 Rémi Patriat, Tara Palnitkar, Jayashree Chandrasekaran, Karianne Sretavan, Henry Braun, Essa Yacoub, Robert A. McGovern, Joshua Aman, Scott E. Cooper, Jerrold L. Vitek, Noam Harel
The thalamus is a centrally located and heterogeneous brain structure that plays a critical role in various sensory, motor, and cognitive processes. However, visualizing the individual subnuclei of the thalamus using conventional MRI techniques is challenging. This difficulty has posed obstacles in targeting specific subnuclei for clinical interventions such as deep brain stimulation (DBS). In this

No effects of the theta-frequency transcranial electrical stimulation for recall, attention control, and relation integration in working memory Front Hum Neurosci (IF 2.9) Pub Date : 2024-02-19 Michał Ociepka, Suvarna Rekha Chinta, Paweł Basoń, Adam Chuderski
IntroductionRecent studies have suggested that transcranial alternating current stimulation (tACS), and especially the theta-frequency tACS, can improve human performance on working memory tasks. However, evidence to date is mixed. Moreover, the two WM tasks applied most frequently, namely the n-back and change-detection tasks, might not constitute canonical measures of WM capacity.MethodIn a relatively

Motor imagery therapy improved upper limb motor function in stroke patients with hemiplegia by increasing functional connectivity of sensorimotor and cognitive networks Front Hum Neurosci (IF 2.9) Pub Date : 2024-02-19 Wan Liu, Xinxin Cheng, Jiang Rao, Jiawen Yu, Zhiqiang Lin, Yao Wang, Lulu Wang, Danhui Li, Li Liu, Run Gao
BackgroundMotor imagery therapy (MIT) showed positive effects on upper limbs motor function. However, the mechanism by which MIT improves upper limb motor function is not fully understood. Therefore, our purpose was to investigate the changes in functional connectivity (FC) within and outside the sensorimotor network (SMN) induced by MIT associated with improvement in upper limb motor function in stroke
