Evolution of nervous systems
The evolution of nervous systems dates back to the first development of nervous systems in animals (or metazoans). Neurons developed as specialized electrical signaling cells in multicellular animals,...

Ray Kurzweil: Get ready for hybrid thinking
Two hundred million years ago, our mammal ancestors developed a new brain feature: the neocortex. This stamp-sized piece of tissue (wrapped around a brain th...
Primates With Big Brains Eat Fruit

How being bilingual rewires your brain
We know that being bilingual has cognitive benefits. But now, research suggests that it can fundamentally alter the structure of your brain.
Scientists Reprogram Brain With a Beam of Light --"Human Brain is Plastic, Not Hardwired" -
Neurons that fire together wire together, say scientists at Columbia University, suggesting that the three-pound computer in our heads may be more malleable than we think. Their findings suggest that ...
Your brain does not process information and it is not a computer
Your brain does not process information, retrieve knowledge or store memories. In short: your brain is not a computer
Where exactly are the words in your head?
Scientists have created an interactive map showing which brain areas respond to hearing different words. The map re...
Action potential
In physiology, an action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in...

Evolution of the brain
The principles that govern the evolution of brain structure are not well understood.Brain to body size does not scale isometrically (in a linear fashion) but rather allometrically. The brains and bodi...
Cephalization
Cephalization is considered an evolutionary trend, whereby nervous tissue, over many generations, becomes concentrated toward one end of an organism. This process eventually produces a head region wit...
Brain size
The size of the brain is a frequent topic of study within the fields of anatomy and evolution. Brain size is sometimes measured by weight and sometimes by volume (via MRI scans or by skull volume). N...
Evolution of human intelligence
The evolution of human intelligence refers to a set of theories that attempt to explain how human intelligence has evolved. These theories are closely tied to the evolution of the human brain and to t...
