How accurate are virtual assessments of cognitive function?

Virtual care provided through telephone or videoconference has been broadly implemented in recent months because of the COVID-19 pandemic. A new analysis of published studies has examined the accuracy and reliability of virtual compared with in-person cognitive assessments for diagnosing dementia or mild cognitive impairment. ....

The neural mechanism of autonomous learning uncovered by researchers at IBEC

Credit: Brainx3.com, SPECS lab.
Thanks to the so-called deep learning, a subset of artificial intelligence (AI) algorithms inspired by the brain, machines can match human performance in perception and language recognition and even outperform humans in certain tasks. But do these synthetic biologically inspired systems learn in the same way that we do?
According to a new article by first author Dr. Diogo Santos-Pata from the Synthetic Perceptive, Emotive and Cognitive Systems lab (SPECS) at IBEC led by ICREA Professor Paul Verschure, in collaboration with Prof. Ivan Soltesz at Stanford University, the mechanism of autonomous learning underlying these AI systems reflects nature more closely than previously thought. With their hypothesis and model, these scientists offer new insights into how we learn and store memories. ....

Social cognition plays a key role in everyday lives of people with multiple sclerosis

.
The authors are Helen M. Genova, PhD, of Kessler Foundation s Center for Neuropsychology and Neuroscience Research, and Stefano Ziccardi, PhD, Marco Pitteri, PhD, and Massimiliano Calabrese, MD, of the University of Verona. Dr. Genova also has an academic appointment at Rutgers University.
Some recent MS research, including work led by Dr. Genova, has shown that social cognition deficits may affect people with MS who otherwise have no other cognitive impairments. Social cognition, which is required to understand and process the emotions of others, is an extremely important skill set for forming successful relationships with others, and deficits in this area can significantly affect a person s quality of life. ....

Uncovering the effects of prior knowledge on learning and memory in bird experts

E-Mail
The Canadian Institute of Health Research (CIHR) has awarded a team of scientists at Baycrest s Rotman Research Institute (RRI) a prestigious grant to determine why having prior knowledge on a topic affects how we learn new, related information as we age. This research will pave the way for optimizing the use of prior knowledge to preserve and improve memory as we get older, ultimately helping older adults live life to the fullest.
Prior knowledge has been shown in animals to transform the cortex - that is, the outer layers of the brain - from being a slow learner to a fast integrator of new knowledge related to old knowledge. With our research, we aim to determine whether a similar process takes place in the human brain and whether this can help offset age-related memory decline, says Dr. Gilboa, a senior scientist at the RRI, an associate professor of psychology at the University of Toronto and the principal investigator on the study. ....

Simple treatment during pregnancy can protect baby from memory problems in later life

E-Mail
A new study in laboratory rats has discovered a direct link between low oxygen in the womb and impaired memory function in the adult offspring. It also finds that anti-oxidant supplements during pregnancy may protect against this.
Low oxygen in the womb - known as chronic fetal hypoxia - is one of the most common complications in human pregnancy. It can be diagnosed when a routine ultrasound scan shows that the baby is not growing properly and is caused by a number of conditions including pre-eclampsia, infection of the placenta, gestational diabetes or maternal obesity.
The new results show that chronic fetal hypoxia leads to a reduced density of blood vessels, and a reduced number of nerve cells and their connections in parts of the offspring s brain. When the offspring reaches adulthood, its ability to form lasting memories is reduced and there is evidence of accelerated brain ageing. ....
