Researchers at UC San Diego discovered that the brains of humans and chickens share comparable regions for analyzing auditory inputs. The study found laminated layers of cells linked by narrow columns in both species, indicating that complex cognitive functions may have evolved from ancient vertebrates.
Researchers have discovered a new stem cell in the developing human brain that produces nerve cells forming the neocortex, the site of higher cognitive function. The study sheds light on developmental diseases such as autism, schizophrenia, and Alzheimer's disease, and could lead to novel therapies.
Researchers discover complex events initiated by individual spikes in the human cerebral cortex, triggered by specific chandelier cells. The study suggests that humans possess different types of cells contributing to higher cognition.
Researchers found that PKMzeta is necessary for storing long-term memories in the neocortex, a part of the brain responsible for higher-level cognitive functions. Persistent phosphorylation by PKMzeta is crucial for storing these memories.
Research finds that music training fine-tunes brainstem's sensitivity to speech sounds, benefiting learning activities, and potentially improving sound encoding skills. The study suggests a dynamic relationship between the brainstem and neocortex, allowing basic sensory circuitry to be malleable.
Researchers recorded activity in two brain regions during deep sleep, finding a complex 'dialogue' between the hippocampus and neocortex. The findings suggest that the neocortex drives communication during sleep, contradicting previous theories of hippocampal control.
Research at Karolinska Institutet reveals that human neocortical nerve cells do not regenerate, contradicting previous studies on apes and rodents. The new method uses atmospheric C14 levels to pinpoint cell birth times, showing no cell division took place in the neocortex from infancy to adulthood.
Researchers studied individual neurons in cats' neocortex to understand multisensory integration, finding that many neurons can respond to multiple senses. The findings suggest that early sensory experiences play a significant role in shaping brain circuitry, with potential implications for treating disorders such as autism and dyslexia.
A study published in Science found no new neurons in the neocortex of adult monkeys, contradicting previous reports. Researchers used advanced imaging techniques to analyze thousands of cells and conclude that mechanisms other than neurogenesis may be needed to understand brain function.
