Specialization of the human hippocampal long axis revisited.

The hippocampus possesses anatomical differences along its long axis. Here, we explored the functional specialization of the human hippocampal long axis using network-anchored precision functional MRI in two independent datasets (N = 11 and N = 9) paired with behavioral analysis (N = 266 and N = 238). Functional connectivity analyses demonstrated that the anterior hippocampus was preferentially correlated with a cerebral network associated with remembering, while the posterior hippocampus selectively contained a region correlated with a distinct network associated with behavioral salience.

Within-individual organization of the human cognitive cerebellum: Evidence for closely juxtaposed, functionally specialized regions.

Specific regions in the cognitive cerebellum are connected to distinct cerebral association networks. Do these cerebellar regions exhibit functional specialization similar to the cerebral cortex? Here, we mapped the cerebellum within intensively studied participants ( = 15) first using connectivity to estimate regions linked to specific networks and then prospectively testing functional response properties in task data within each individual's own idiosyncratic anatomy. A large megacluster extending across Crus I/II was consistently found with subregions linked to five higher-order association networks.

A hierarchical atlas of the human cerebellum for functional precision mapping.

The human cerebellum is activated by a wide variety of cognitive and motor tasks. Previous functional atlases have relied on single task-based or resting-state fMRI datasets. Here, we present a functional atlas that integrates information from seven large-scale datasets, outperforming existing group atlases.

Precision Network Modeling of Transcranial Magnetic Stimulation Across Individuals Suggests Therapeutic Targets and Potential for Improvement.

Higher-order cognitive and affective functions are supported by large-scale networks in the brain. Dysfunction in different networks is proposed to associate with distinct symptoms in neuropsychiatric disorders. However, the specific networks targeted by current clinical transcranial magnetic stimulation (TMS) approaches are unclear.
