This study reveals a role for the superior colliculus in higher-order cognition, independent of its role in spatial orienting. Researchers found that the superior colliculus exhibits robust encoding of learned visual categories and its inactivation markedly impaired category decisions in rhesus macaques.
Researchers have found that the total surface area (TSA) of the cerebral cortex is linked to cognitive performance, while mean cortical thickness (MCT) is associated with schizophrenia risk. The study used Mendelian randomization to establish causal relationships between cortical morphology and neuropsychiatric traits.
The article details a study suggesting that rapid shifts in gene regulation, rather than changes in protein-coding genes, likely drove the evolution of human intelligence. Researchers identified two key regulatory "saltations" – sudden changes – unique to humans that impact areas like memory, learning, social behavior, and emotional depth.
A study examining the impact of gut microbiome modulation via prebiotic supplementation on muscle function and cognitive performance in older adults, finding no significant improvement in muscle function but a beneficial effect on cognition.
"The brainy birds carry big chips on their shoulders, scientists say. And some people who become subjects of their ire may be victims of mistaken identity."
* A study by Dr. John Marzluff found that crows can hold a grudge for up to 17 years.
* Experts believe that crows may attack humans due to mistaken identity, with some cases possibly triggered by the presence of similar-looking individuals (e.g., people with long blond hair).
* Some Vancouver residents have found creative ways to avoid or appease the crows, such as bribing them with food.

A new study reveals that when engaging in complex cognitive tasks, the brain's activity becomes more detailed and streamlined, allowing for efficient processing. The findings suggest the brain adjusts its patterns of activity to match task demands.
Explores the dynamic relationship between language, cognition, and the role of Large Language Models (LLMs) in expanding our understanding of the functional significance of language.
This study explores the role of the Wnt pathway in regulating dendritic spine morphology and synaptic function. The authors found that activation of the Wnt pathway leads to the formation of new spines and enhances synaptic strength. Their findings suggest a novel mechanism by which the Wnt pathway influences synaptic plasticity and cognitive function.
