New study by Prof. Benny Hochner from the Alexander Silberman Institute of Life Sciences at The Hebrew University and Prof. Jeff Lichtman from Harvard University has unveiled the intricate neural architecture governing the enigmatic learning processes of Octopus vulgaris. This research introduces a promising model for delving into memory networks, with implications for both cephalopods cognition, considered the most intelligent invertebrates, and broader insights into memory processes, including those in humans.
Older adults who play digital puzzle games have the same memory abilities as people in their 20s, a new study has shown.
Brain imaging of neuron activity in certain areas of the brain may predict whether an individual is likely to successfully respond to interventions to reduce their drinking. In a study published in Alcohol: Clinical and Experimental Research, individuals whose baseline imaging showed decreased activity in areas of the brain associated with reward processing and impulsivity and increased activity in regions responsible for complex cognitive processes and emotional regulation were more likely to reduce their drinking following an intervention.
New research shows that popular brain signatures of prediction error are only generated in the presence of attention to the visual stimuli, despite early brain encoding of those stimuli.
Unlike previously thought, speech production and singing are supported by the same circuitry in the brain. Observations in a new study can help develop increasingly effective rehabilitation methods for patients with aphasia.

Scientists from Immanuel Kant Baltic Federal University worked out a system of artificial intellect, that analyzes information about academic performance and tracks which themes is pupil good or bad at, which educative skills he lacks and which tasks bring him into stressful condition.
Neurons become active when mice exploring a maze correct after making a wrong turn.
Eighty percent of older adults see the benefit of tests that can give an early warning that a person’s memory and thinking abilities have started to decline, a new poll of people age 65 to 80 finds. And 60% think that health care providers should offer cognitive screening to all older adults every year
Indiana University researchers have made a substantial discovery in the role genes play in the development of AUDs, finding that alteration of a group of genes known to influence neuronal plasticity and pain perceptions, rather than single gene defect, is linked to AUDs.
A team of scientists led by researchers from the University of Leicester have discovered that the genes required for learning, memory, aggression and other complex behaviours originated around 650 million years ago.
Valentina Harmjanz often tapped into music on her smartphone to connect with older patients she visited at William P. Clements Jr. University Hospital. The UT Southwestern medical student met with patients as part of the Hospital Elder Life Program (HELP), a joint effort between UTSW and the Hobson Wildenthal Honors College at the University of Texas at Dallas.
Cognitive abilities not only vary among different species but also among individuals within the same species. It is expected that smarter individuals live longer, as they are likely to make better decisions, regarding habitat and food selection, predator avoidance, and infant care.
Musical rhythms can help children with speech and language processing difficulties in finding their voice by improving their capacity to repeat sentences they just heard, according to a study led by a Western Sydney University researcher and co-authored by Vanderbilt University Medical Center.
Motor learning skills let us move through the world: we use them to teach ourselves how to walk, how to pick up a drink, how to run. But age or sickness can weaken our ability to learn motor tasks.
Board games based on numbers, like Monopoly, Othello and Chutes and Ladders, make young children better at math, according to a comprehensive review of research published on the topic over the last 23 years.
How well do children know letters and their corresponding sounds? In Norway, the gender difference on these tasks when children start school is significant. The girls have a clear head start. New results published in the journal Acta Psychology show that this discrepancy is not the case for first graders in Iceland.
Distinct, though neighboring, areas of the brain are activated when processing music and language, with specific sub-regions engaged for simple melodies versus complex melodies, and for simple versus complex sentences, according to research from UTHealth Houston.
Despite the fears of parents, screen time doesn’t appear to have overwhelmingly negative impacts on preschoolers’ development, new research suggests. The study of kids from low-income and minority homes found that the quantity of time in front of the TV, smartphones and tablets was not related to children’s gains in language, literacy and math skills.
A recently-published study led by Prof. Einat Levy-Gigi, from Bar-Ilan University, examined for the first time the interactive effect of exposure to stress in the school setting and cognitive flexibility on the tendency to develop post-traumatic symptoms among education and teaching staff. One hundred fifty education and teaching personnel (85% women and 15% men with an average age of 43 and average teaching experience of 13 years) volunteered to participate in the study and underwent an assessment of their exposure to stress, their cognitive flexibility, their ability to cope and their level of post-traumatic symptoms.
Climbing trees, making mud pies, or simply playing outside, parents and educators know that being in nature is an important part of every childhood. But when it comes to messy or risky play, it’s a whole different story according to new research from the University of South Australia.

A study by researchers at Washington University School of Medicine in St. Louis reveals that household and community poverty may influence brain health in children. Childhood obesity and lower cognitive function may explain, at least partially, poverty’s influence on the brain.
One in four Americans live with a disability, which is associated with stigma and disparities in health care. New research examined differences in alcohol use by disability status and types of disability, and found a need for a range of accommodations in alcohol treatment and recovery services – including technology-based options. These results and others will be shared at the 46th annual scientific meeting of the Research Society on Alcohol (RSA) in Bellevue, Washington.

While summer is a time for fun in the sun, we often hear of parents expressing their concern about the “summer slide.” It’s when the loss of learning opportunities during the break lead to regression in reading and math. Some studies suggest up to a month of learning is lost over the summer, but according to Tonya Price, a 4-H youth development extension specialist with Virginia Cooperative Extension, there are many things that can be done to keep children learning and engaged while out of the classroom.
Receptor patterns define key organisational principles in the brain, scientists have discovered.
