- (medicine, transitive) To surgically separate the spinal cord of (an animal) from the brain.
- 2008, Mark L. Latash, Neurophysiological Basis of Movement:
- Such procedures may involve surgically separating the spinal cord from the brain. In this case, the animal is called spinalized or a spinal preparation. If we assume that every volitional act comes from the brain, then in a spinalized animal all muscle reactions to external stimuli are apparently reflexes, because signals from the brain cannot reach the spinal cord.
- 2012, James Tresilian, Sensorimotor Control and Learning: An Introduction to the Behavioral Neuroscience of Action:
- An injury that results in complete spinal transection at the thoracic or cervical level has the same effect as the surgical procedure used to spinalize animals for use in experiments.
- 2014, Shih-Chii Liu, Event-Based Neuromorphic Systems, page 94:
- This conceptual experiment can be physically demonstrated by decerebrating or spinalizing an animal and using a neuromuscular blockade or deafferentiation to remove rhythmic sensory feedback.
