Child’s Home Learning Environment Predicts 5th Grade Academic Skills

Children whose parents provide them with learning materials like books and toys and engage them in learning activities and meaningful conversations in infancy and toddlerhood are likely to develop early cognitive skills that can cascade into later academic success, finds a new study by NYU’s Steinhardt School of Culture, Education, and Human Development.

Brain Scan Study Adds to Evidence That Lower Brain Serotonin Levels Are Linked to Dementia

In a study looking at brain scans of people with mild loss of thought and memory ability, Johns Hopkins researchers report evidence of lower levels of the serotonin transporter — a natural brain chemical that regulates mood, sleep and appetite.

Cognitive Hearing Aid Filters Out the Noise

Cognitive hearing aids that constantly monitor brain activity to determine whether a subject is conversing with a specific speaker would be very useful for the hearing impaired. Using deep neural network models, Columbia Engineering researchers have made a breakthrough in auditory attention decoding methods and are coming closer to making cognitively controlled hearing aids a reality. The study, led by Electrical Engineering Professor Nima Mesgarani, is published today in the Journal of Neural Engineering.

For White Middle Class, Moderate Drinking Is Linked to Cognitive Health in Old Age

Older adults who consume alcohol moderately on a regular basis are more likely to live to the age of 85 without dementia or other cognitive impairments than non-drinkers, according to a University of California San Diego School of Medicine-led study.

Stress + Alcohol Can Disrupt Cognitive Function, Impair Prefrontal Cortex

Drinking alcohol results in an alcohol use disorder (AUD) when consumption becomes excessive and dependence develops. Both stress and anxiety can contribute to the development of an AUD. Chronic stress can increase drinking, and chronic drinking can elevate anxiety and dysregulate normal responses to stressors. Behavioral flexibility and adaptive behavior – essential for controlling excessive drinking – are core functions of the prefrontal cortex (PFC), This study used mice to examine the effects of combined alcohol and stress exposure on PFC function.

Scientists Use New Data Mining Strategy to Spot Those at High Alzheimer’s Risk

The push to develop treatments for Alzheimer’s disease has yielded a greater understanding of the disease, but has failed to generate successful new drugs. To blame are the many undefined subtypes of mild cognitive impairment, a precursor to Alzheimer’s disease. But if scientists grouped people with similar types of cognitive impairment, they could more precisely test the impact of investigational drugs, according to findings in a July 28 article in the journal Scientific Reports, a publication of Nature Research.

Drug Improves Brain Performance in Rett Syndrome Mice

A brain penetrant drug — a small-molecule mimetic of BDNF, or brain derived neurotrophic factor — is able to improve brain performance in Rett syndrome mice — specifically synaptic plasticity in the hippocampus and object location memory. The hippocampus is involved in learning and memory.

Even Babies Can Tell Who's the Boss, UW Research Says

University of Washington researchers have found that the trait of social dominance, and the dynamics surrounding it, may be so naturally ingrained that toddlers as young as 17 months old not only can perceive who is dominant, but also anticipate that the dominant person will receive more rewards.
