Driving brain rhythm makes mice more sensitive to touch

By striking up the right rhythm in the right brain region at the right time, Brown University neuroscientists report in Nature Neuroscience that they managed to endow mice with greater touch sensitivity than other mice, making ...

Handful of genetic changes led to huge changes to human brain

Changes to just three genetic letters among billions led to evolution and development of the mammalian motor sensory network, and laid the groundwork for the defining characteristics of the human brain, Yale University researchers ...

Happiness and the evolution of brain size

During human evolution, the size of the brain increased, especially in a particular part called the neocortex. The neocortex enables us to speak, dream and think. In search of the causes underlying neocortex expansion, researchers ...

Human brain size gene triggers bigger brain in monkeys

The expansion of the human brain during evolution, specifically of the neocortex, is linked to cognitive abilities such as reasoning and language. A certain gene called ARHGAP11B that is only found in humans triggers brain ...

Sleep frees up the hippocampus for new memories

Two regions of our brain are central for storing memories: the hippocampus and the neocortex. While the hippocampus is primarily responsible for learning new information and its short-term storage, the neocortex is able to ...

MRI scans reveal how brain protects memories

Two distinct parts of the human brain—the neocortex and the hippocampus (a part of the brain involved in higher-order brain functions) - have been shown to help protect our memories from interfering with one another.

Neocortex

The neocortex (Latin for "new bark" or "new rind"), also called the neopallium ("new mantel") and isocortex ("equal rind"), is a part of the brain of mammals. It is the outer layer of the cerebral hemispheres, and made up of six layers, labelled I to VI (with VI being the innermost and I being the outermost). The neocortex is part of the cerebral cortex (along with the archicortex and paleocortex, which are cortical parts of the limbic system). In humans, it is involved in higher functions such as sensory perception, generation of motor commands, spatial reasoning, conscious thought and language.
