Modern Humans Generate More Brain Neurons Than Neanderthals

Study reveals greater neuron production in the modern human frontal lobe during development compared to the Neanderthal brain. Researchers say this is due to a change in a single amino acid in the TKTL1 protein.

Axolotls Can Regenerate Their Brains

Axolotls have the ability to regenerate brain areas following an injury. Researchers have mapped cell types and genes associated with neurodegeneration in the axolotl brain, discovering some similarities in the human brain. The findings could pave the way for new neurodegenerative therapies.

Dragons and Brain Evolution

Researchers created a molecular atlas of the bearded dragon's brain and compared it to the mouse brain. Findings reveal, contrary to popular belief, mammalian brains consist of an ancient reptilian brain supplemented with new mammalian features. Both reptilian and mammalian brains evolved their own clade-specific neuron types and circuits from a common ancestral set.

When Humans Gesture, They Activate an Ancient Connection Between Movement and Breathing

A new study sheds light on why humans often use hand movements while talking. Researchers report rhythmic hand gestures affect rib cage movements, leading to a change in lung volume and ultimately aspects of the voice. Infants connect early vocal babbling with hand gestures, demonstrating an early connection between movement and vocal production.

Did Gonorrhea Give Us Grandparents?

Researchers have identified a set of genetic mutations that protect against cognitive decline in older adults. A new study suggests the selective pressure from infectious pathogens like gonorrhea may have promoted the emergence of this genetic variance in Homo sapiens.
