A neurologist is a specialist who diagnoses and treats diseases of the nervous system, which includes the brain, spinal cord, and peripheral nerves. They use a variety of methods, including imaging tests and neurological examinations, to diagnose and treat conditions like multiple sclerosis, Parkinson's disease, and stroke.

A neurosurgeon is a specialist who performs surgical procedures on the brain, spinal cord, and peripheral nerves. They use minimally invasive techniques to treat tumors, trauma, stroke, and other conditions. They also use a variety of imaging tests to guide the operation and monitor the outcome.

Neurosurgeons are doctors who specialize in the diagnosis and surgical treatment of diseases and disorders of the nervous system, which includes the brain, spine, spinal cord, and nerves. Neurosurgeons perform surgery to treat conditions involving the brain and nervous system, such as brain tumors, aneurysms, spinal cord injuries, and spinal stenosis. They also diagnose and treat a variety of neurological conditions, such as Parkinson's disease, multiple sclerosis, stroke, and epilepsy.

Minimally invasive surgery (MIS) is a surgical technique that uses small incisions and advanced technology to perform a procedure. It allows surgeons to perform complex operations with fewer risks and less pain than traditional open surgery. MIS can be used for a variety of procedures including joint replacement, hernia repair, gastrointestinal surgery, and many other operations.

Neurosurgeons typically use a variety of testing machines such as computerized tomography (CT) scanners, magnetic resonance imaging (MRI) scanners, ultrasound machines, and electromyography (EMG) machines. These machines are used to diagnose neurological conditions and aid in the planning of surgical procedures.
