Developmental delay is a deviation from the regular development of normative milestones during childhood. Early stimulation is a standardized and straightforward technique to support children with developmental delays (aged 0-3 years) in reaching basic motor skills, which are essential for the execution of everyday activities, such as playing, feeding and locomotion. In doing so, early stimulation reduces the chances of permanent motor impairment, thus allowing the child to live a more functional life. However, outcomes of this treatment depend heavily on the involvement of the family, who are required to continue the early stimulation activities at home on a daily basis. To empower and educate families to administer standardized early stimulation programs at home, we developed an electronic early stimulation program, which provides personalized guidance to parents to administer early stimulation; together with evidence-based clinical decision support to therapists in tailoring ESP to observed needs.

The population receptive field (pRF) method, which measures the region in visual space that elicits a blood-oxygen-level-dependent (BOLD) signal in a voxel in retinotopic cortex, is a powerful tool for investigating the functional organization of human visual cortex with fMRI (Dumoulin & Wandell, 2008). However, recent work has shown that pRF estimates for early retinotopic visual areas can be biased and unreliable, especially for voxels representing the fovea. Here, we show that a log-bar stimulus that is logarithmically warped along the eccentricity dimension produces more reliable estimates of pRF size and location than the traditional moving bar stimulus.

Background: How tauopathy disrupts direct entorhinal cortex (EC) inputs to CA1 and their plasticity is understudied, despite its critical role in memory. Moreover, dysfunction of lateral EC (LEC) input is less clear, despite its relevance to early Alzheimer's disease pathogenesis. Here we examined how tau impacts long-term potentiation (LTP) of LEC→CA1 input in a transgenic model of tauopathy.

Background: Stress is a common modifiable risk factor for AD, which increases dementia risk 2-fold. During the stress response, the hypothalamic-pituitary adrenal (HPA) axis is activated which stimulates the release of stress hormones called glucocorticoids into the blood stream. Studies on early-life stress have shown a glucocorticoid dependent vulnerability towards late-life inflammation.

Background: Mitochondrial dysfunction is an early and prominent feature of Alzheimer's disease (AD). We have recently published that lower brain mitochondrial DNA copy number (mtDNAcn) is associated with increased risk of AD neuropathological change and reduced cognitive performance. Here, we addressed how mtDNAcn affects cell-type specific phenotypes.

Background: Microglia, the innate immune cells of the brain, are a principal player in Alzheimer's Disease (AD) pathogenesis. Their surveillance of the brain leads to interaction with the protein aggregates that drive AD pathogenesis, most notably Amyloid Beta (Aβ). Aβ can elicit attempts from microglia to clear and degrade it using phagocytic machinery, spurring damaging neuroinflammation in the process.
