An electrical signal within a single neuron travels from _______
a layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next
There are more Excitatory Inputs than Inhibitory Inputs

Peripheral Nervous System
the sensory and motor neurons that connect the central nervous system to the rest of the body
Parasympathetic Nervous System
The division of the autonomic nervous system known as the 'resting and digesting' system. It causes a general decrease in body activities such as heart rate, respiratory rate, and blood pressure; increase in digestion
Sympathetic Nervous System
The division of the autonomic nervous system that mobilizes the body's resources during stress and emergencies, preparing the body for action.
Somatic Nervous System
the division of the peripheral nervous system that controls the body's skeletal muscles
interconnected neural cells; with experience, networks can learn, as feedback strengthens or inhibits connections that produce certain results; in the Central Nervous System
Autonomic Nervous System
the part of the nervous system of vertebrates that controls involuntary actions of the smooth muscles and heart and glands
a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
a technique that uses magnetic fields and radio waves to produce computer-generated images that distinguish among different types of soft tissue; allows us to see structures within the brain
a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body.
chemical messenger that is secreted by an endocrine gland carried by the bloodstream; slow-acting but long-lasting
half of the brain generally specializes in analysis, calculation, problem solving, verbal communication, interpretation, language, reading & writing. It receives info and controls opposite of the body.
half of the brain specializes in perception of physical environment, art, nonverbal communication, music & spiritual aspects. It receives information from and controls the opposite side of the body.
the fibers that connect the right and left hemispheres, enabling them to communicate
controls language reception-a brain area involved in language comprehension and expression;in the left temporal lobe

the brain's capacity for modification, as evident in brain reorganization following damage (especially in children) and in experiments on the effects of experience on brain development
that part of the cerebral cortex in either hemisphere of the brain lying inside the temples of the head; lies below the frontal lobe, responsible for hearing, taste, and smell
the intricate fabric of interconnected neural cells that covers the cerebral hemispheres; the body's ultimate control and information-processing center
areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking
a doughnut-shaped system of neural structures at the border of the brainstem and cerebral hemispheres; associated with emotions such as fear and aggression and drives such as those for food and sex. Includes the hippocampus, amygdala, and hypothalamus.
a neural center located in the limbic system that helps process explicit memories for storage
two almond-shaped neural clusters that are components of the limbic system and are linked to emotion

neurotransmitter that affects mood, sleep, hunger, and arousal; lack of is linked to depression
that part of the cerebral cortex in either hemisphere of the brain lying directly behind the forehead; associated with movement, speech, and impulsive behavior
that part of the cerebral cortex in either hemisphere of the brain lying below the crown of the head, posterior to the frontal lobe; responsible for sensations such as pain, temperature, and touch
that part of the cerebral cortex in either hemisphere of the brain lying in the back of the head, posterior to the parietal and temporal lobes; responsible for vision
