What is motor imagery BCI?
Motor imagery based Brain Computer Interface (MI BCI) provides an interface for the patients with motor impairment or those who are in completely locked-in-state to interact with the environment by controlling robotic prostheses, wheelchairs, and other devices [15].
What can BCI do?
A BCI is a computer-based system that acquires brain signals, analyzes them, and translates them into commands that are relayed to an output device to carry out a desired action. Thus, BCIs do not use the brain’s normal output pathways of peripheral nerves and muscles.
How are signals processed in the brain?
Neurons communicate with each other by sending chemical and electrical signals. Each neuron is connected with other neurons across tiny junctions called “synapses”. Impulses rush along tiny fibres, like electrical wires, from one neuron to the next. Electrical impulses travel through neurons.
What are brain signals called?
Neurons
Whats the biggest part of the brain?
The cerebrum (front of brain) comprises gray matter (the cerebral cortex) and white matter at its center. The largest part of the brain, the cerebrum initiates and coordinates movement and regulates temperature.
Which is the smallest part of brain?
The midbrain is the smallest region of the brain, and is located most centrally within the cranial cavity. Limbic System – the limbic system is often referred to as our “emotional brain”, or ‘childish brain’. It is found buried within the cerebrum and contains the thalamus, hypothalamus, amygdala and hippocampus.
