Progressive, age-dependent remodeling of motor cortex somatotopic remodeling is demonstrated in 5XFAD mice, characterized by early expansion of specific simple movement cortical sites followed by deterioration of both complex and simple motor cortical maps as disease advances.
The basal ganglia are characterized by somatotopic representation and are organized in parallel, functionally segregated corticostriatal circuits, but the impact of Parkinson’s disease (PD) on this architecture is unknown, and both anatomical and functional segregation were lost in PD.

Trans transcranial magnetic stimulation with electromyography is used to investigate mechanisms of motor cortical excitability in biomarker-positive early-AD participants and 72 cognitively unimpaired age-matched adults and shows that early-AD participants have increased motor cortical excitability, related to cognitio...

PCA is associated with a distribution of NFT pathology that coincides with early predominant visuospatial impairment in EOAD generally and may moderate degree of visuospatial impairment in EOAD regardless of clinical syndrome.

This work uses an adeno-associated virus-induced longitudinal macaque model of Alzheimer’s disease to examine early changes in behavior, neuronal population activity, and pathology and suggests that early disease is accompanied by a progressive loss of coordinated population activity.

The optogenetic, electrophysiological, pharmacological, and CRISPR-mediated genetic studies demonstrated that impaired α5-GABAA receptor-mediated inhibition and excessive activation of NMDA receptors of M1 pyramidal neurons are key microcircu it mechanisms underlying cortical circuit remodeling during progressive stria...

Overall, Aβ plaque deposition was related to brain-region-specific differences in microglial responses, indicating that visual brain regions are differentially affected by AD pathology in the 5xFAD mouse model of amyloidosis.
