Part Of The Brain Huntington Disease
1,403 words... led a master of the history of brain science since the 1800 s. A little after his time, a Vietnamese physician named Fransod believed he could localize distinctions of character in areas in the brain, if fact in very small and accurate areas in the brain. He believed that if there was a certain trait that you were good at, you would get a lump of some sort that had enlarged that part of your brain. Many people believed that, and soon there were cartoons drawn of people with huge lumps in cer...

Stimulants On Your Consciousness 5 Ht Similarly Dopamine
693 wordsThe Effects of Stimulants on Your Consciousness A stimulant is a drug that stimulates your body and mind activity. Some of the most commonly used stimulants are caffeine, cocaine, amphetamines, and Ecstasy (MDMA, methylenedioxyamphetamines). Out of the above listed caffeine is the most widely used and has very mild side effects. Caffeine is found in coffee, teas, soda, and chocolate. Since we all know a lot about caffeine I will not be discussing it. However I will be covering my two personal fa...

Patients With Als Fact That Glutamate Skin
641 wordsThis theory is based on the fact that glutamate, an amino acid present in proteins, can cause neuronal cell death when present in high concentration. The specific evidence for the excitotoxic theory comes from the demonstration of decreased levels of glutamate in ALS spinal cord, with the assumption that glutamate must have been released and must have been present in high concentrations that would have been toxic. In addition, there is a decreased ability of glutamate to be taken up in fractions...

Neuro Transmission Positive Charge
488 wordsneurotransmitters play a central and critical role in our psychological existence, identity, and experience of the world Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the cell membrane causes...

Shown In Figure Neuromuscular Junction
1,660 wordsProteins involved in formation of the neuromuscular junction The neuromuscular junction is a specialized junction, where a motor nerve forms its synaptic terminal with a muscle fibre, one of many fibres that make up a whole muscle. The mature neuromuscular junction is composed of three types of cells - a motor nerve terminal, a muscle fibre and a Schwann cell covering the junction. All three of these cells are highly differentiated and specialized for their functions (Kandel 2000, p. 1089). The ...

Central Nervous System Peripheral Nervous System
1,365 wordsThe definition of Brain as given in the Taber's Cyclopaedia Medical Dictionary is "Brain- a large soft mass of nerve tissue contained within the cranium; the carnal portion of the central nervous system. The anatomy of the brain is composed of neurons (nerve cells) and neuroglia or supporting cells. The brain consists of gray and white matter. Gray matter is composed mainly of neuron cell bodies and is concentrated in the cerebral cortex and the nuclei and basal ganglia. White matter is composed...

Stem Cells The Miracle Cure
1,092 wordsIn order to develop an opinion on whether or not stem cells should be used, one first must understand what they are and how they are used. Simply stated, the definition of a stem cell is an undifferentiated cell, meaning that it has no true function yet. However, all of the genes within a human stem cell have the potential to become other types of cells. The triggering mechanism for this is for the stem cells to be placed among specialized cells. Specialized cells include skin cells, muscle cell...

Second, 'psychotomimetic effects similar to those induced by PCP can be induced by ketamine, a related arylcyclohexamine derivative' (Sevvenson, 1995). This is a particulary strong point of evidence, especially when coupled with the following point: A dosage of ketamine ten times that of PCP is required in order to induce the same effect (Halberstad, 1995).

Central Nervous System Spinal Cord
888 wordsSpinal Cord Regeneration Spinal cord injury can occur in many ways ranging from gunshot wounds, stab wounds and also bone displacement. These circumstances can lead to the death of neurons, and the demyelination of axons which causes some loss and damage to neurons. As Hudgins (1998) reports after a primary injury such as above, secondary injury occurs 30 minutes after and also that secondary injury is when the most critical damage occurs. This is when there is hemorrhaging in the gray matter of...
