Insights from Comparative Genome Study of Humans and Great Apes on Gut Microbiome Development

A comparative genome study of humans and great apes has provided insight into the development of the gut microbiome, revealing that the microbial colonization of a living organism is highly host-specific and follows the evolution of the host. The study, conducted by scientists from the Collaborative Research Center 1182, compared microbiome data from various great apes with those of humans with rural and urban lifestyles, finding that the species diversity of the human microbiome is reduced in comparison with apes. The research also identified the loss of evolutionarily conserved bacterial groups in humans with urban lifestyles, shedding light on possible functional adaptations of the human microbiome and their implications for disease development.

Unveiling the Power of Light in Reviving Forgotten Memories

Researchers have used in-depth imaging to study the medial temporal lobe (MTL), a crucial region for memory, and have discovered new cortical networks associated with the MTL. This study provides insights into human memory and potential evolutionary developments. The researchers overcame challenges of anatomical variability and susceptibility artifacts by collecting detailed data from individual subjects. The findings shed light on the connectivity of the MTL with the rest of the brain and highlight potential new cortical pathways in the human memory system compared to non-human primates. The study also suggests that one of the networks connected to the human entorhinal cortex, a region affected early in Alzheimer's disease, may be an evolutionarily young network involved in social processing.

The Evolution of Cognitive Flexibility.

A study by researchers at the Berufsgenossenschaftliches Universitätsklinikum Bergmannsheil and Newcastle University has provided insights into the evolutionary origins of cognitive flexibility, an essential skill for adaptation and survival. The study used functional magnetic resonance imaging (fMRI) to examine the brain functions of 40 participants while they were learning a sensorimotor task. The findings showed the importance of sensory brain regions in decision-making and surprising similarities between the brain activity of humans and mice during this task, suggesting that the interplay between the frontal brain and sensory brain regions for decision-making formed early in evolutionary development.
