Old Brain
What is the part of the brain responsible for transmitting information between the brain and the body?
Brainstem
What small organ found below the thalamus is responsible for maintaining homeostasis (Temperature, hunger, thirst, etc.) and provides a link between the endocrine and neural system?
Hypothalamus
What is the name of the thin layer of gray matter covering of the Cerebrum which is responsible for most high-level functions of the brain?
Cerebral Cortex
What does the motor cortex, located in the frontal lobe, do?
Directs movements
On average, how heavy is the human brain?
3 lbs (1.4 kg)
What part of the brain is responsible for sending sensory information to the respective areas of the higher brain, and occasionally responding to the medulla and cerebellum?
The Thalamus
What two almond-shaped parts of the brain is responsible for aggression and fear?
Amygdala
What lobe of the brain is responsible for judgement and decision making?
Frontal Lobe
What nerve carries visual information to the brain?
Optic Nerve
Approximately what percentage of neurons can be found in the Cerebellum?
80%
What two parts of the brain are located at the bottom of the brainstem, and are responsible for the vast majority of all autonomic functions, such as coordination, breathing, heartbeat, and swallowing? (You must include both!)
Pons & Medulla
What does the limbic system do?
Provide a connection between the new and the old brain
What lobe, situated next to your ears and below the rest of the lobes, is responsible for processing audio?
Temporal Lobe
What does Wernicke’s area, found in the left posterior superior temporal gyrus, do?
Process language to ensure it makes sense.
How many sensory neurons can be found in the brain?
Zero
This part of the brain, colloquially known as the “Little Brain,” is responsible for refining information and instructions, coordinating movement, memory and learning, as well as many other functions. What is it?
Cerebellum
What does "limbic" roughly translate to?
What lobe is responsible for receiving information from sensory neurons?
Parietal Lobe
What part of the brain ensures language is produced fluently?
A researcher plants an electrode into an area of the brain, and the subject reports seeing a sudden spot of light. What part of the brain was likely stimulated?
Occipital Lobe (Or Visual Cortex)
This part of the brain controls arousal, and filters information coming from the brainstem. What is it?
Reticular Formation
The responsibilities of the Basal Ganglia include:
Motor control, motor learning, executive functions and behaviors, and emotions
What function does the occipital lobe preform?
Visual processing
Severing the ___ can result in a phenomenon known as “Split Brain Syndrome,” where the two hemispheres of the brain cannot communicate.
Corpus Callosum
Theoretically, what is the maximum amount of information that can be stored by the brain?
2.5 Petabytes (2.5x10^15 bytes)
