1. Introduction Epilepsy is defined as a brain disorder characterized by an enduring predisposition togenerate seizures (International League Against Epilepsy (ILAE) and the InternationalBureau for Epilepsy (IBE)‚ 2005). It is a neurological disorder consisting of recurrentseizures that resulted from excessive‚ uncontrolled electrical activity in the brain (Wang‚2011). The ancient Babylonian believed that seizures can occur when a person wasvisited by a demon and thus‚ the different kinds of seizures

Sannu’s Story A. In Sannu’s case why is there both sensory loss and muscle weakness? Leprosy is a disease that has been known since biblical times. It causes skin sores‚ nerve damage‚ and muscle weakness that gets worse over time. Leprosy is caused by the bacterium Mycobacterium leprae. It is not very contagious and it has a long incubation period (time before symptoms appear)‚ which makes it hard to know where or when someone caught the disease. Children are more likely than adults to get the

Young. Her information was clearer and makes much more sense‚ scientifically‚ than Jeffrey A Schaler’s article. Young ad some solid test and evidence about what drug addiction has on the brain‚ neurons and neurotransmitters. Though I’m not an advocate for animal testing‚ they provided information about the circuits involved in the ventral segmental area‚ the nucleus accumbens and the frontal cortex.(8) (Young‚ Alice M. 1999. “Addictive Drugs and the Brain”)

"The foundation for much of what we know about sleep was gathered approximately 40 years ago by researcher‚ Michel Jouvet. This French scientist studied the effects of gross brain lesions and brain transections on sleep behavior and related phenomena. It was Jouvet who first suggested that a brainstem region is responsible for the initiation of events that result in the stage of sleep called REM sleep. REM sleep is a stage associated with rapid eye movements‚ a high degree of brain wave activity

Dopamine Regulates the Motivation to Act‚ Study Shows The widespread belief that dopamine regulates pleasure could go down in history with the latest research results on the role of this neurotransmitter. Researchers have proved that it regulates motivation‚ causing individuals to initiate and persevere to obtain something either positive or negative. The neuroscience journal Neuron publishes an article by researchers at the Universitat Jaume I of Castellón that reviews the prevailing theory on

A muscle is a group of cells called fibers‚ and are generally quite big. One muscle fiber has a large amount of myofibrils‚ which are muscle proteins in the shape of cylinders. These myofibrils contain two different types of filaments‚ which run along the axis of the fiber in hexagonal patterns. The two types of filaments are thick and thin filaments. Every thick filament is surrounded by six thin filaments. Both thick and thin filaments are attached to a structure called the Z-line. The Z-line runs

Foundations of Psychology Paper PSY/300 May 13‚ 2012 Psychology encompasses a vast range of different thoughts‚ theories‚ and biological foundations on behavior of why people act the way they do. Once a part of philosophy‚ psychology has developed into several schools of thought that describe the theories some of these individuals use to approach what they are observing from different people and their actions. Some of these theories do have conflictions from others‚ but all have a good amount

the synapses with numerous others. As a result‚ small electrical currents are discharged by the neurons in a bid to discharge neurotransmitters of the synaptic degree to allow communication with one another. Numerous neuromodulators or neurotransmitters are established to have a responsibility in the neuronal excitation. Nonetheless‚ the main excitatory neurotransmitters inside the brain are the L-glutamate (Engel‚ 2013). As such‚ the abnormal operations of the L-glutamate could lead to a seizure
