The cortical connectome of primate lateral prefrontal cortex

Rui Xu et al.

Summary: This study reveals the connectivity between the lateral prefrontal cortex (LPFC) and the rest of the cortex. The results show isomorphic mappings between LPFC and other major processing domains, suggesting LPFC's role in coordinating activity within and across these domains.

Use of Functional MRI to Assess Effects of Deep Brain Stimulation Frequency Changes on Brain Activation in Parkinson Disease

Marisa DiMarzio et al.

Summary: This study aimed to investigate the impact of altered frequencies on brain activation in PD patients. It was found that changing the frequency significantly affected the activation levels in regions such as the thalamus, globus pallidum externa, and cerebellum. Additionally, using fMRI signatures may be helpful in determining the optimal frequency for DBS programming.

The nonhuman primate neuroimaging and neuroanatomy project

Takuya Hayashi et al.

Summary: Studies using nonhuman primates (NHPs) enable comparisons between invasive and non-invasive measures to better understand human brain connectivity and structure.

Brain rhythms define distinct interaction networks with differential dependence on anatomy

Julien Vezoli et al.

Summary: Cognitive functions are supported by rhythmic neuronal synchronization across various brain areas, and the distinct interaction networks defined by different rhythms were not explained by the spatial distributions of the strengths of the rhythms. The networks, especially the Granger causality networks, exhibited clear modular structures with one dominant rhythm per module. Anatomy was found to be primarily related to coherence and Granger causality, with the largest effect sizes for Granger causality, and the correlation between functional interaction metrics and anatomical projection strength varied between rhythms, being less pronounced for beta and strongest for gamma rhythm.
