This fascinating lecture explores the function of numerous neurotransmitters in both the peripheral and central nervous system. The transmitters include norepinephrine, dopamine, epinephrine, serotonin, acetylcholine, GABA, and glutamate. Who is "sara" and why does she make you so happy? Who put the dope in dopamine? What are the many functions of dopamine, besides the obvious "feel good, let's do it again" role in addictive behaviors? GABA is your "momma"...she's inhibitory and she helps to keep "the brake's on" your behavior. Drugs that mimic her function are called "Mother's Little Helpers" —the class of drugs known as the benzodiazepines. GABA is also a primary target for many anticonvulsants as well. Norepinephrine gives you energy and stimulates your appetite center. Prednisone is a primary culprit to stimulate the release of norepinephrine in the appetite center. Acetylcholine is the transmitter of cognition in the brain and has numerous functions in the peripheral nervous system as well as the enteric nervous system. Glutamate is excitatory and plays a role in head injury, strokes, and schizophrenia. This fascinating lecture correlates the function of each of these neurotransmitters with their roles in common clinical conditions as well as all of the drugs used to treat each of these conditions—antidepressants, antipsychotics, anticonvulsants, anticholinergics, and more.

An atlas and textbook that combines nearly 400 illustrations and radiologic images highlighting key neuroanatomical concepts and clinical correlations with updated information that reflects our current understanding of the nervous system. It offers user-friendly coverage in three parts-an overview of the nervous system, regional neuroscience, and systemic neuroscience- that enable you to review complex neural structures and systems from different contexts.
Barb takes a "journey" through the brain—the Cerebral Cortex (all four lobes and their functions), and shows how to assess the 4 lobes as well as pathophysiology, including head injuries, brain tumors, and dementias; the basal ganglia and assessment, including the patient with a movement disorder—Parkinson's disease, Huntington's chorea, and athetosis; the brain stem—assessment and clinical correlations including cranial nerves; spinal cord and the reflex arc. It's a great lecture for neuro novices as well as seasoned neuro nurses—everyone learns some new tidbits as well as refreshing some old tidbits. (website)
