Teen Brains at Risk: Common Herbicides Linked to Cognitive Dip

Herbicides, notably glyphosate and 2,4-D, have been associated with adverse effects on adolescent brain function, according to researchers from the University of California San Diego. Findings show the ubiquitous presence of these herbicides in the urine of adolescents in Pedro Moncayo, Ecuador, and associate higher herbicide concentrations with poorer neurobehavioral performance.

Mild cognitive impairment was diagnosed by a panel of researchers who reviewed each participant´s performance across several tests.

Subtle Test Deficits: A Quiet Prelude to Cognitive Decline?

A recent study reveals a potential predictive indicator for mild cognitive impairment (MCI), often a forerunner to dementia, in individuals reporting subjective cognitive decline yet displaying only subtle test deficits. The investigation, encompassing 439 participants averaging 71 years of age, identified that those with minor test deficits were over four times more likely to progress to MCI compared to their counterparts without such deficits.

This shows a person surrounded by numbers.

Perception Puzzles: Our Brain’s Unique Counting Methods

A new study reveals intriguing insights into how our brains perceive different quantities of objects. When faced with a small number of items (four or fewer), our brains can quickly and accurately determine the count, a phenomenon known as "subitizing." Conversely, with five or more items, our estimation becomes increasingly imprecise and time-consuming.

Prenatal Phthalate Exposure Linked to Brain Size and Child IQ Reduction

A new study linked higher prenatal exposure to certain phthalates with reduced gray matter in children's brains by age 10. This exposure was also correlated with decreased IQ levels in the offspring at age 14.

Neighborhood Woes: How Living Conditions Impact Brain Structure and Diet

Living in disadvantaged neighborhoods not only influences food choices and weight gain but can also alter the brain's microstructure. Researchers found that poor food quality, high-calorie intake, and inactive environments common in such areas disrupt brain regions crucial for emotion, cognition, and reward processing.

Mice in Maze Shed New Light on Rodent Learning and Cognition

Researchers have delved deeper into mouse behavior, challenging previous assumptions about their cognitive strategies in reward-based learning tasks. While humans efficiently adopt the "win-stay, lose-shift" approach in "reversal learning" activities, mice were observed to blend this with an exploratory strategy.

Early Concussions Tied to Faster Cognitive Decline

A recent study reveals a link between early-life concussions and faster cognitive decline in later years. Conducted on World War II veteran twins, the research showed that twins with a history of traumatic brain injury (TBI) scored lower on cognitive tests and exhibited quicker decline than their non-injured counterparts.

This shows two toddlers playing with a developmental toy.

Toddlers Use Logic Before Language

Toddlers as young as 19 months old exhibit natural logical thinking, independent of language knowledge. This ability, manifesting as exclusion by elimination, allows toddlers to make conclusions about unknown realities by discounting known impossibilities. \
