Researchers believe findings may shed light on how the vertebrate brain may have evolved.
According to researchers, the adult subcortex processes numbers at the same level of skill as infants.
Researchers report that, at the molecular levels, aging may have originated at the beginning of the evolution of life. They suggest when it comes to genes, aging may not always be a negative trait, and may help an organism to survive.
Researchers report the neural code of the prefrontal cortex is more efficient than the amygdala in both humans and primates. The lower resistance of the amygdala to errors in humans may play a role in exaggerated survival responses, such as those seen in anxiety and PTSD.
The Tsimane, an indigenous people from the Bolivian Amazon, have less brain atrophy than American aging adults, a new study reports. Additionally, the decrease in their brain volume associated with aging is 70% less than seen in older American adults.
A new study raises the question of whether a genetic mutation associated with neurodegeneration in one environment could act in a positive way in a different setting.
