Topic: anterior hippocampus

This study investigates the cognitive mechanism of adapting memory sequences to changing contexts, a process well-utilised by humans but not yet fully understood. Initially conducted in rats (n=8), and later adapted for both new-world (common marmosets, n=5), and old-world monkeys (Rhesus macaques, n=2), the research aimed to assess each animals' proficiency in learning complex context-guided sequences. Furthermore, by use a new non-invasive technique called transcranial ultrasound stimulation (TUS), the study sought to explore the underlying neurobiological pathways involved in a nonhuman pri

Studies suggest the basolateral amygdala (BLA) modulates memory-consolidation processes via interactions with downstream brain regions like the hippocampus. Furthermore, direct electrical stimulation of the BLA in humans enhances declarative memory, and this memory enhancement is marked by oscillatory interactions between the BLA and hippocampus. However, the BLA disproportionately projects to the anterior hippocampus compared to the posterior hippocampus, regions that process non-spatial information about objects and spatial information about scenes, respectively. Nevertheless, the premise th

Aim. Obstetric brachial plexus palsy (OBPP) is a common motor impairing condition caused by birth injury. The present study, using voxel- and surface-based morphometry (VBM and SBM), was aimed to examine brain structure of pediatric OBPP patients, to better understand effects of this peripheral condition on early brain development. Methods. Thirty-six T1-weighted images of 18 patients (2-17 years old, mean age=11.3, 8 females) and 18 healthy controls (HC) (2-17 years old, mean age=10.1, 8 females) were collected via Philips Ingenia ElitionX 3.0T scanner. MRI data were processed and analyzed us
