Parts of the Brain
This procedure causes a change in brain activity by the destruction/removal of brain tissue
What is a lesion?
These are neurons that carry outgoing information from the brain and spinal cord to the muscles
What are motor neurons?
________ results when one fertilized egg splits into two.
What are identical twins?
This is the study of how the environment "turns on" or "blocks" gene expression.
This uses magnets and radiowaves to produce 3D images.
What is an MRI?
This is the The oldest part and central core of the brain; includes the reticular formation and is in charge of automatic survival functions
What is the brainstem?
This is the period of inactivity after a neuron has fired
What is the refractory period?
A random error in gene replication that leads to a change
What is a mutation?
Someone who is a split brain patient and sees HE-ART will only be able to point to this word.
What is he?
This type of scan is best used to see brain activity while the brain is active; it utilizes a radioactive substance that mimics glucose.
What is a PET scan?

What is the pons?
This is the division of the autonomic nervous system that calms the body, conserving its energy
What is the parasympathetic nervous system?
Every nongenetic influence, from prenatal nutrition to the people and things around us
What is the environment?
This part of the brain helps to control arousal.
What is the reticular formation?
This is best used to diagnose seizures.
What is an EEG?
This regulates growth and controls other endocrine glands. It is controlled by the hypothalamus.
What is the pituitary gland?
This says that increasing the level of stimulation will NOT increase the neural impulse's intensity.
What is the all-or-none response?
This contains all of an organisms' genetic material in the chromosomes.
What is the genome?
The periphal nervous system contains the ________ and __________ subsystems.
What are the autonomic and somatic systems?
This scan can quickly show intracranial bleeding.
What is a CT scan?
This is a group of neural structures associated with emotions like fear, agression, and drives such as those for food
What is the limbic system?
This increases a neurotransmitter's action.
What is an agonist?
This serves as a guide to the cultural norms that are expected of people.
What is a social script?
This happens when "extra" neurotransmitters are reabsorbed.
What is reuptake?
This is the newest form of imaging. It is painless and noninvasive.
What is MEG?
