Background: The long-term impact of childhood maltreatment (CM) on an individual's physical and mental health is suggested to be mediated by altered neurodevelopment. However, the exact neurobiological consequences of CM remain unclear.
Methods: The present study aimed to investigate the relationship between CM and brain age based on structural magnetic resonance imaging data from a sample of 214 adults.

Objective: The effectiveness and optimal stimulation site of deep brain stimulation (DBS) for central poststroke pain (CPSP) remain elusive. The objective of this retrospective international multicenter study was to assess clinical as well as neuroimaging-based predictors of long-term outcomes after DBS for CPSP.
Methods: The authors analyzed patient-based clinical and neuroimaging data of previously published and unpublished cohorts from 6 international DBS centers.

A fundamental topological principle is that the container always shapes the content. In neuroscience, this translates into how the brain anatomy shapes brain dynamics. From neuroanatomy, the topology of the mammalian brain can be approximated by local connectivity, accurately described by an exponential distance rule (EDR).

Background: Alzheimer's disease (AD) is a neurological disorder marked by progressive cognitive decline, memory deficits, and neuronal cell loss (Knopman, 2021). A brain region significantly impacted by the progression of AD is the subiculum, a structure responsible for spatial navigation, cognitive processes, and the modulation of emotional and affective behaviors within the hippocampus (Fanselow and Dong, 2010). Although subiculum cell loss has been well-established as an early indicator of AD (Carlesimo et al.

Background: Identification of cell-type vulnerability in Alzheimer's Disease (AD) is critical to the clinical development of targeted treatments. Neurodegeneration of the subiculum (SUB) is an early biomarker of AD, but it is unknown if specific SUB cell-types are susceptible to AD neurodegeneration. In the 5xFAD mouse model, significant cell loss occurs within the SUB by 8 months of age.
