HMB200H1 Lecture Notes - Lecture 1: Anterior Grey Column, Brainstem, Neurosurgery
Document Summary
The robots would move when people approached them by stepping on levers and she thought of reflexive behavior. She thought the brain controlled muscle to move via nerves which had fluids or spirits running thru them. Dualism dominated the thouhgts of neuroscience for a long time. The neuromuscular junction was the first thing studied in the nervous system. The sgnal on the muscle originated from the spinal cord and it originated from neurons in the ventral horn of the spinal cord. The cell body of the neuron is in the ventral horn of the spinal cord. The neurons in the spinal cord have axons that snapse with neurons in the brain. They synapse with neurons in the motor cortex, some in the brainstem, some in the midbrain. All of them eventually have cnnections to the motor cortex. We keep the lower levels because they were selected for in the past and because they are used for reflexes.
