Terms in this set (30)
one of a class of neurotransmitters that bind to opiate receptors and moderate pain
cells in the nervous system that support, nourish, and protect neurons
a neural structure lying below the thalamus; directs eating, drinking, body temperature; helps govern the endocrine system via the pituitary gland, and is linked to emotion
the junction between two neurons (axon-to-dendrite) or between a neuron and a muscle
areas of tissue that have been pathologically altered by injury, wound, or infection
the brain's sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
A neural center located in the limbic system that helps process explicit memories for storage
a band of nerve fibers linking the medulla oblongata and the cerebellum with the midbrain
the "little brain" attached to the rear of the brainstem; it helps coordinate voluntary movement and balance
a neurotransmitter that affects hunger,sleep,arousal,and mood. appears in lower than normal levels in depressed persons
part of the brain nearest the spinal cord which controls breathing, heart rate and blood pressure
neurotransmitter that influences voluntary movement, attention, alertness; lack of dopamine linked with Parkinson's disease; too much is linked with schizophrenia
The level of stimulation required to trigger a neural impulse.
the different regions into which the cerebral cortex (the Brain) is divided
the large band of neural fibers connecting the two brain hemispheres, carrying messages between them
a pair of endocrine glands just above the kidneys. the adrenals secrete the hormones epinephrine (adrenaline) and norepinephrine (noradrenaline), which help to arouse the body in times of stress.
two almond-shaped neural clusters that are components of the limbic system and are linked to emotion
Central Nervous System
the portion of the vertebrate nervous system consisting of the brain and spinal cord
L - dopa
parent molecule for dopamine and is given to parkinson's disease patient as dopamine cannot cross the blood brain barrier while this parent molecule can cross
MRI (Magnetic Resonance Imaging)
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
chemical messengers that traverse the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.
an amplified recording of the waves of electrical activity that sweep across the brain's surface. These waves are measured by electrodes placed on the scalp.
a major part of the central nervous system which conducts sensory and motor nerve impulses to and from the brain
Blood Brain Barrier
Blood vessels (capillaries) that selectively let certain substances enter the brain tissue and keep other substances out
the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
largest part of a typical neuron; contains the nucleus and much of the cytoplasm
Reticular Activating System
Part of brain stem involved in arousal and attention, sleep and wakefulness, and control of reflexes.
the system of glands that produce endocrine secretions that help to control bodily metabolic activity
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.
area 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.
