Hippocampal region CA2 has received increased attention due to its importance in social recognition memory. While its specific function remains to be identified, there are indications that CA2 plays a major role in a variety of situations, widely extending beyond social memory. In this targeted review, we highlight lines of research which have begun to converge on a more fundamental role for CA2 in hippocampus-dependent memory processing. We discuss recent proposals that speak to the computations CA2 may perform within the hippocampal circuit.

Social technology in older adults can improve self-rated health; however, there can also be difficulties using it. Our study aimed to evaluate the feasibility and acceptance of virtual assistant device (VAD) use in cognitively impaired homebound older adults. 52 newly referred Meals on Wheels clients aged 60 and older were recruited for a three-phase study: 6 weeks of meals alone (control), followed by 6 weeks of meals+Alexa Echo Show 8 (AES8) basic usage, and lastly 6 weeks of meals+AES8 advanced usage.

Understanding the pathophysiology of inflammatory skin diseases, including psoriasis, atopic dermatitis (AD), and prurigo nodularis (PN), has led to the development of innovative treatments. In the February issue of the Journal, we provide insight into the global epidemiology and psychosocial impact of psoriasis. We also discuss the role of tissue-resident memory T cells in disease recurrence and evaluate the effectiveness of tildrakizumab in treating difficult areas in psoriasis.

Background: Cognitive reserve (CR), typically measured through socio-behavioral proxies, can partially explain better cognitive performance despite underlying brain aging or neuropathology.
Objective: To examine the associations of CR with mild cognitive impairment (MCI) and cognitive function while considering Alzheimer's disease (AD)-related plasma biomarkers.
Methods: This population-based cross-sectional study included 4706 dementia-free individuals from MIND-China.

The development of inhibitory control (IC) and working memory (WM) in preschool is linked to a multitude of cognitive, emotional, and social outcomes, including elementary school adjustment. Furthermore, there are both cognitive and socioemotional domains of IC and it is unclear if both are related to these outcomes in the same manner. Using a family study design, the present investigation examined preschoolers' IC, WM and externalizing behavior problems, maternal depression and anxiety measured when the children were in preschool, and elementary school externalizing behaviors and child and family functioning.
