Human brains outpace chimp brains in the womb

A new study tracked brain growth in human and chimpanzee fetuses, finding that human brains begin to show remarkable differences after 22 weeks of gestation. The findings suggest a faster rate of brain growth in humans compared to chimpanzees.

More sophisticated wiring, not just bigger brain, helped humans evolve beyond chimps

A new UCLA study identifies uniquely human patterns of gene activity in the brain that could deepen our understanding of human evolution and brain diseases. The research suggests that complex signaling pathways and enhanced cellular function in the frontal lobe created a bridge to human evolution, enabling higher rates of learning.

Brain capacity limits exponential online data growth

A study found that the human brain's ability to process information is the dominant limiting factor for exponentially growing internet data. The distribution of internet files shows a Weber-Fechner law, where the total amount of information grows slower than our ability to handle it.

Changes in the path of brain development make human brains unique

A new study found that human brain development differs from chimpanzees and macaques, with hundreds of genes showing unique developmental patterns in the prefrontal cortex. MicroRNA activity patterns also showed significant differences, potentially linked to human-specific changes in cognitive abilities.

Like humans, chimps are born with immature forebrains

A recent study tracking chimpanzee brain development found that both humans and chimps have immature forebrains at birth. The study's findings suggest that this developmental delay may provide an extended period of plasticity, enabling both species to develop complex social skills.

Just add water and treat brain cancer

Researchers have developed a novel gene therapy system using nanoparticles that can be freeze-dried and stored for up to three months. The technology shows promise in treating brain cancer with high efficacy and minimal risk of complications, offering a potential alternative to traditional therapies.

New route to map brain fat

Researchers develop a new method to visualize lipid distribution in the human brain, revealing detailed information about neurodegenerative diseases. The study uses imaging mass spectrometry and functional autoradiography to identify 43 types of lipids in three distinct brain regions.

Brain size and a trip to Disneyland

A new study suggests that human creativity may have evolved as a way for parents to bond with their children, passing on cultural knowledge and traditions. This theory challenges the idea that creativity emerged from courtship behaviors, proposing instead that it arose from parental influences.

$30 million project will map the brain's wiring

A five-year, $30-million Human Connectome Project will generate a map of the brain's major circuits using powerful scanners and analysis techniques. The project aims to understand brain connectivity and function to advance brain health and develop new treatments for disorders like autism and schizophrenia.

Baby brain growth mirrors changes from apes to humans

A study found that the human brain regions growing during infancy and childhood are similar to those with the most changes when comparing humans to apes and monkeys. This research helps assess adverse effects of premature birth on brain development, including increased risks of learning disabilities and cognitive impairments.

Human brain recognizes and reacts to race

Research at University of Toronto Scarborough found that the human brain is more reactive to people of one's own race, producing significantly more motor-cortex activity, whereas observing others from a different race results in reduced activity. The study suggests that this phenomenon may contribute to prejudice and limited empathy.

Exploring status quo bias in the human brain

A study by UCL scientists found that people tend to accept the status quo and avoid making complex decisions, even when it leads to errors. The study used fMRI scans to examine the neural pathways involved in 'status quo bias' and discovered a key role for the subthalamic nucleus in overcoming this bias.

Caltech scientists find first physiological evidence of brain's response to inequality

Researchers found that the brain responds more strongly to a poor person receiving a financial reward than a rich person, even if the brain being studied belongs to the rich individual. This study suggests that the human brain is wired to respond to inequality, contradicting the prevailing view of human nature as solely self-interested.

Brain-controlled cursor doubles as a neural workout

Researchers at the University of Washington studied brain signals in eight patients awaiting epilepsy surgery, finding that imagined movements can strengthen brain activity. After less than 10 minutes of practice, brain signals from imagined movement became significantly stronger than when actually performing the physical motion.

Transcription factors guide differences in human and chimp brain function

Researchers found that broad differences in gene activity between humans and chimps are coordinated by about 90 transcription factors, which affect nearly 1,000 genes. This suggests a unique regulatory mechanism in the human brain that allows for larger brains and different organ functions.

Why can't chimps speak?

A UCLA/Emory study discovered significant differences between the human and chimp versions of the FOXP2 gene, which may explain why humans developed language while chimps did not. The research provides insight into the evolution of the human brain and may lead to new drug targets for disorders characterized by speech disruption.
