100
This imaging technique uses magnetic fields and radio waves to produce detailed images of the brain.
What is Magnetic Resonance Imaging, or MRI
100
This is the largest part of the brain.
What is the Cerebrum?
100
This system of the brain is involved with emotion, aggression, appetites, and sexual behavior.
What is the limbic system?
100
This is the largest of the four lobes of the cerebrum.
What is the frontal lobe?
100
This structure (in red and purple) is necessary for balance and fine motor control. It also holds about 80% of the Brain's 86 billion neurons.
What is the Cerebellum?
200
The ventricles of the brain and spaces in the spinal cord hold this fluid.
What is cerebral spinal fluid
200
The cerebrum is divided into these two structures.
What are the left and right cerebral hemispheres? (or left and right hemispheres)
200
This type of glia wraps several axons at a time with myelin.
What are oligodendrocytes?
200
This part of the cerebrum is key to our sense of smell.
What is the olfactory bulb?
200
The green section indicated by the pointer, in this mid-sagittal view of the brain, represents nerve tracts that connect the two cerebral hemispheres, so they can communicate.
What is the Corpus Collosum?
300
The folding of the cerebral cortex leads to bumps or ridges called __________________.
What are Gyri?
300
The two halves of the cerebrum are connected by a tract of neurons known as the _________________.
What is the corpus collosum?
300
This part of the limbic system is especially important for fear emotions and fear memory.
What is the amygdala?
300
This part of the frontal lobe is crucial for personality; higher level-cognition and decision making, problem solving, attention and also some memory functions.
What is the Pre-frontal Cortex?
300
This part of the brain (in red) connects the cerebrum to the spinal cord and is crucial for vital functions like consciousness, sleep-wake cycles, heart and respiratory control.
What is the Brain Stem?
400
The Hippocampus, Amygdala, and and Basal Ganglia are all derived from this embryonic division of the brain.
What is the Telencephalon?
400
This is the technical name given to the "grooves" that characterize the human cerebral cortex.
What are sulci?
400
This group of structures play an important role in controlled and coordinated movements. Damage to it causes movement dysfunctions and is associated with neurodegenerative diseases like Parkinson’s and Huntington’s diseases.
What are the Basal Ganglia?
400
This lobe of the cerebrum, located posterior and inferior to the parietal lobe, is responsible for processing our vision.
What is the occipital lobe?
400
This brain structure (indicated by the unnamed pointer) is important for homeostasis and control of basic functions. It is located "under" the thalamus.
What is the hypothalamus?
500
A very large meta study that combined 30 years of data (Eliot, 2021) concluded that male and female brains are not structurally different in a meaningful way. Which means that there is no sexual _______________ of the brain in our species. (its a technical biological term - not "difference")
What is dimorphism?
-the condition in which a single species has two distinct forms, colors, sizes, or structures.
500
The purpose for the wrinkled folding of the human cerebral cortex is to provide this.
What is increase surface area?
500
This ion rushes across the membrane of a neuron and into the cell when an action potential reaches that point on the membrane.
What are sodium ions?
500
This lobe of the cerebrum is key for language, memory, hearing and face perception.
What is the Temporal lobe?
500
This type of scan uses x-rays to produce images of the brain.
What is a computerized tomography scan (CT and CAT acceptable though CAT is no longer used as the acronym)
