The Spinal Cord
This part of the nervous system connects the brain to the outside world. It routes messages to and from the brain and controls reflexes.
What is the spinal cord?
What happens when blood flow to a part of the brain is interrupted
What is a stroke?
This lobe is involved with reasoning and motor control. It contains the motor cortex and the Broca's area.
What is the frontal lobe?
This hindbrain structure is one of the most important in the brain. It processes memories involved with performing tasks, and it receives messages from the body so it can control balance, coordination, and movement
What is the cerebellum?
This brain imaging technique involves placing people inside of a machine with a magnetic field. It moves hydrogen atoms in the body, and the computer interprets the signals given off by the atoms when they return to their original positions.
What is magnetic resonance imaging (MRI)?
What happens when a segment of the spinal cord is damaged
What is the cutting off of lower segments and the causing of paralysis?
The specialization of functions (within the brain)
What is lateralization?
This lobe processes information from the senses and contains the somatosensory cortex
What is the parietal lobe?
This hindbrain structure regulates brain activity during sleep, it is part of the brainstem
What is pons?
This brain scanning technique relies on taking multiple X-rays of a section of the brain. These x-rays pass through different tissues and different rates, and an image of the brain is produced. This technique is most commonly used to determine if someone has a tumor.
What is a computerized tomography (CT) scan?
How the nervous system can change and adapt
What is neuroplasticity?
The surface of the brain and its folds and grooves
What is the cerebral cortex and its gyri and sulci?
This lobe contains the primary visual cortex and is responsible for processing visual information
What is the occipital lobe?
This hindbrain structure controls breathing, blood pressure, and heart rate
What is the medulla?
This brain imaging technique involves the injection of a radioactive substance (tracer) in order to track blood flow in the brain. It creates a rough map of active and inactive areas of the brain.
What is a positron emission tomography (PET) scan?
The spinal cord is organized into this amount of segments
What is 30?
The thick band of neural fibers that connect the two hemispheres of the brain
What is the corpus callosum?
These are the three most important parts of the limbic system
What is the hippocampus, the amygdala, and the hypothalamus
This structure, found in the midbrain, regulates the sleep/wake cycle, arousal, alertness, and motor activity
What is the reticular formation?
This brain imaging technique shows changes in brain activity over time by tracking blood flow and oxygen levels. This technique provides a more detailed map of the brain than PET scans and has mostly replaced them
What is functional magnetic resonance imaging (fMRI)?
The spinal cord is protected by bony vertebrae and cushioned in this fluid
What is cerebrospinal fluid?
The most prominent sulcus
Longitudinal fissure
This lobe, located on the side of the head, is responsible for some aspects of hearing, memory, emotion, and language. It contains the auditory cortex and Wernicke's area.
What is the temporal lobe?
Both of these structures contain cell bodies that produce dopamine, are important for movement, are involved with mood, reward, and addiction, and are found within the midbrain
What is the substantia nigra and the ventral tegmental area (VTA)?
This technique involves the placing of electrodes around a person's head and tracking the signals received in the form of electrical activity
What is electroencephalography (EEG)?
