The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system. The brain integrates sensory information and coordinates instructions sent to the rest of the body.
there’s a new breed of wearables—built for your head. Instead of tracking your step count, heart rate, and skin temperature, these devices are designed to read your brain waves. Using electroencephalography, or EEG, they detect electrical impulses produced by the brain and use AI to make sense of them.
A brain–computer interface (BCI), sometimes called a brain–machine interface (BMI), is a direct communication link between the brain‘s electrical activity and an external device, most commonly a computer or robotic limb. BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions.[1] They are often conceptualized as a human–machine interface that skips the intermediary of moving body parts (e.g. hands or feet). BCI implementations range from non-invasive (EEG, MEG, MRI) and partially invasive (ECoG and endovascular) to invasive (microelectrode array), based on how physically close electrodes are to brain tissue.[2]

Neuroprosthetics is an area of neuroscience concerned with neural prostheses, that is, using artificial devices to replace the function of impaired nervous systems and brain-related problems, or of sensory or other organs (bladder, diaphragm, etc.). As of December 2010, cochlear implants had been implanted as neuroprosthetic devices in some 736,900 people worldwide.[24] Other neuroprosthetic devices aim to restore vision, including retinal implants. The first neuroprosthetic device, however, was the pacemaker.[citation needed]
The terms are sometimes used interchangeably. Neuroprosthetics and BCIs seek to achieve the same aims, such as restoring sight, hearing, movement, ability to communicate, and even cognitive function.[1] Both use similar experimental methods and surgical techniques.[citation needed]
Brainstorm is a 1983 American science fiction film directed by Douglas Trumbull, and starring Christopher Walken, Natalie Wood (in her final film role), Louise Fletcher, and Cliff Robertson
Overview
Researchers Michael Brace (Christopher Walken) and Lillian Reynolds (Louise Fletcher) develop a system that allows the recording and playback of a person’s thoughts onto videotape. The project spins dangerously out of control when Brace and his colleagues begin using the technology to explore intense sexual and near-death experiences. When the military moves to hijack the project for their own nefarious purposes, Brace tries to outwit them with help from his estranged wife (Natalie Wood).
