Brain Basics
This largest part of the brain is responsible for higher functions like thinking and decision-making.
What is the cerebrum?
This disorder is often characterized by recurring seizures and abnormal electrical activity in the brain.
What is Epilepsy?
This organ is responsible for the sense of taste, with specialized cells for each basic taste.
What is the tongue?
This part of the nervous system controls involuntary actions like digestion and heart rate.
What is the autonomic nervous system?
This organ only makes up about 2% of your body weight but uses around 20% of your body's total energy.
What is the Brain?
This lobe of the brain processes visual information from the eyes.
What is the occipital lobe?
This neurological disorder, often triggered by loud noises or bright lights, causes severe headaches, including visual disturbances and light sensitivity.
What is a Migraine?
This part of the eye is responsible for focusing light onto the retina.
What is the lens?
This branch of the autonomic system prepares the body for "fight or flight" responses.
What is the sympathetic nervous system?
These special neurons activate when we observe others, helping us learn through imitation and understand emotions.
What are mirror neurons?
This part of the brain controls balance and coordination and is located under the cerebrum.
What is the cerebellum?
A buildup of amyloid plaques in the brain is often linked to this progressive disease associated with memory loss.
What is Alzheimer’s disease?
This sensory system detects changes in temperature, pressure, and pain in the skin.
What is the somatosensory system?
The somatic nervous system controls these types of actions, which are typically under conscious control
What are voluntary actions?
People who lose a limb often report feeling sensations, like itching or pain, where the limb once was, a phenomenon known by this name.
What is phantom limb sensation?
This part of the brain controls the vital signs
What is the Brainstem?
This condition results from damage to the spinal cord and can lead to loss of function below the injury site.
What is Paralysis?
The photoreceptor cells in the retina that detect color are called this.
What are cones?
This autonomic system has two branches: the sympathetic and this branch, often called "rest and digest.
What is the parasympathetic nervous system?
This neurotransmitter is often called the "feel-good" chemical because it plays a key role in the brain’s reward and pleasure centers.
What is dopamine?
This lobe is in control of language, learning, spatial recognition, and processing somatosensory signals.
What is the Parietal lobe?
This neurodegenerative disease is known for causing tremors and stiffness in movement, primarily due to dopamine deficiency.
What is Parkinson's disease?
The tiny hairs in this part of the ear help translate sound vibrations into electrical signals for the brain.
What is the cochlea?
This ANS division is in control of all digestive functions.
What is the Enteric divison?
On average, it takes this much time (in milliseconds) for a human to react to a visual stimulus.
What is around 250 milliseconds?
