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.

Paper proposes new way to understand how the neocortex works

Scientists at Numenta propose a major new theory about how the human brain works. While neuroscientists have amassed an enormous amount of detailed factual knowledge about the brain, there remains no unifying theory as to ...

Scientists discover regional differences among chandelier cells

The brain is composed of distinct regions that differ in their functional roles and cellular architecture. For example, the hippocampus is an area well-known for its involvement in memory and its dysfunction in diseases such ...

The brain's multi-track road to long-term memory

Our brain has a tough task every time we experience something new – it must be flexible to take in new information instantly, but also stable enough to store it for a long time. And new memories may not be allowed to alter ...

Wiring rules untangle brain circuitry

Our brains contain billions of neurons linked through trillions of synaptic connections, and although disentangling this wiring may seem like mission impossible, a research team from Baylor College of Medicine took on the ...

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 ...

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.
