I.Abstract Guillain-Barre Syndrome (GBS) is an auto-immune disease that is rare but can lead to paralysis of limbs and the diaphragm. Ventilatory failure is commonly seen in patients with progressing diseases. The causes of GBS syndrome is unknown‚ however a few culprits are being studied. The most common explanation for GBS is the demyelination of the peripheral nervous system. Other causes in question include flu vaccinations and certain bacteria such as Campylobacter Jejuni. Patients diagnosed

regulation of smooth muscle and cardiac muscle. In the central nervous system acetylcholine is believed to be involved in the sleep-wake cycle‚ learning‚ memory‚ and mood. Acetylcholine is synthesized from choline and acetyl coenzyme A through the action of the enzyme choline acetyltransferase and becomes packaged into membrane-bound vesicles. After the arrival of a nerve signal at the termination of an axon‚ the vesicles fuse with the cell membrane‚ causing the release of acetylcholine into the synaptic

The History of Cell Theory As we all probably know today‚ every single living being is made up by cells the building blocks of life. As much as we would like to take this fact for granted‚ we cannot help but acknowledge and remember the works and discoveries of earlier scientists which all contributed to our today’s understanding of the cell theory. The cell theory being; all living things are composed of one or more cells‚ cells are organisms’ basic units of structure and function‚ and cells

Short Term Memory After reading several articles on short term memory‚ I noticed mostly everyone defines it differently. The most frequent definition is a system for temporarily storing and managing information required to carry out complex cognitive tasks such as learning‚ reasoning and comprehension. It is involved in selection‚ initiation and termination of information - processing functions such as encoding‚ storing‚ and retrieving data. Short term memory is the little thing that completely

Exocytosis and Neuromuscular Junction The Underlying Affect of Botox in our System Botulinum neurotoxin A‚ (BoNT-A)‚ commonly known as Botox‚ is a type of neurotoxin that targets the neuromuscular junction (Merchand-Pauvert‚ V.‚ Aymard‚ C.‚ Giboin‚ L.‚ Dominici‚ F.‚ Rossi‚ A.‚ & Mazzocchino‚ R.

Unit 7. Assignment 2. The Effects of Selected Drugs and Diseases on the Central Nervous System. Alcohol’s use as an anesthetic is based on the effects it has on the brain‚ including relaxation and insensitivity to pain. Because the anesthetizing effects of alcohol are less predictable than the drugs available to modern-day anesthetists‚ alcohol is no longer used professionally to anesthetize patients. Some diseases related to alcohol are: liver disease‚ high blood pressure‚ muscle weakness‚ anemia

How Can The Study Of Aftereffects Tell Us About How The Brain Processes Visual Information? The motion & tilt aftereffect (MTAE; Gibson & Radner‚ 1999) is a simple but intriguing visual phenomenon. After staring at a pattern of tilted lines or gratings‚ subsequent lines appear to have a slight tilt in the opposite direction. The effect resembles an afterimage from staring at a bright light‚ but it represents changes in orientation perception rather than in color or brightness. Most modem
