HOW HUMAN BRAIN WORKS IN SAVING NEW WORDS By: Mitsalina Ardini 1. Introduction We are learning about the brain at an unprecedented rate. Jeri Janowsky‚ a top learning and memory neuroscientist at Oregon Health Sciences University in Portland‚ says‚ “Anything you learned two years ago is already old information. . . . . Neuroscience is exploding”. In the coming years‚ we can expect new and more accurate technologies to further illuminate the brain’s mysteries. For now‚ the following are the

dysfunction‚ systemic symptoms‚ etc.‚ are some aspects of the body in which may be affected by MS and are a result of debilitating transmission of an action potential from nerve cells from the brain to the spinal chord due to the demyelination of the axon (Calabresi‚ 2011). MS is an incurable disease (Boppanna‚ Huang‚ Ito & Dhib-Jalbut‚ 2011). According to Kargiotis‚ Paschali‚ Messinis and Papathanaspolous (2010)‚ treatment options for MS are divided into two

STUDY GUIDE LORENZO’S OIL Overview Lorenzo’s Oil is the story of the Odones’ race against time for the survival of their little boy. Lorenzo at age 6 develops a classic childhood case of Adrenoleukodystrophy. Augusto and Michaela Odone work tirelessly with little assistance from the medical community and the parent support group to find a therapy to stop the progression of this devastating disease. In 2001 Elizabeth Spike‚ a high school biology teacher in Rochester‚ New York‚ chose to show a film

Contraction & Excitation Muscle excitation takes place when there is a synaptic transmission and induction of an impulse. There are six steps that take place during muscle excitation. (1)The action potential travels down the somatic motor neuron axon reaching the synaptic bulb causing calcium ions to flow into the synaptic bulb. (2)The increase of calcium in the synaptic bulb causes the synaptic vesicles to undergo exocytosis. (Exocytosis a process that allows large molecule to leave the cell without

1. TTX blocks the diffusion of sodium through the voltage-gated Na+ channels. 2. Lidocaine blocks the diffusion of Na+ through the voltage-gated channels. 3. With a compound action potential‚ the results would not necessarily be zero because some axons could remain unaffected. 4. TTX blocked the Na+ channels which prevented the propagation of the action potential from R1 to R2. 5. Lidocaine blocks the Na+ channels which prevents the propagation of the action potential from R1 to R2. 6. Lidocaine
