Brain-Computer Interface is a way that the brain waves are monitored and tracked to control activity on a computer. These applications can be used to control characters in video games and to control prosthetic body parts.
Neurobiologists look at the brains of different animals. They are conducting research on the zebra fish's brain and how it responds with different movements.
Scientists are studying tadpoles to look at how their neural circuits develop. These neural circuits are made up of many neurons. Neurons generate electrical and chemical signals in order to communicate with one another.
Scientists are trying to understand how the brain forms and processes emotions. They are conducting research on the brain patterns of positive and negative emotions to understand the brain a little bit better.
The brain is not yet understood by scientists completely. In 2013, the Brain Initiative was put forth and allocated $1 billion in research towards neuroscience to understand the brain more.
