    Inhibitory Potential Changes of Fluoxetine (Prozac) Over the past several decades many scientists have explored the various possible links between the function of neurotransmitters in the brain and mood disorders. The neurotransmitter serotonin, found widely in plants, animals and humans has been a particular focus. Scientists who specialize in examining the function and effect of serotonin on the mind and body argue that imbalances in the levels and function of serotonin can be linked

    Excitatory Potential Changes Risperidone is a serotonin antagonist which blocks GABA-evoked currents in pyramidal neurons (Feng et al, 2001). Risperidone lengthens action potentials and blocks potassium current in rabbit heart muscle. In human atrial muscle risperidone decreases outward current but has no effect on inward current. It lengthens the repolarization of atrial and ventricular action potentials only at high drug levels. Risperidone reduces the membrane resting potential and prolongs

    Inhibitory or Excitatory Potential Changes "MDMA affects the brain by increasing the activity of at least three neurotransmitters (the chemical messengers of brain cells): serotonin, dopamine, and nor epinephrine" (The Brain's Response to Hallucinogens). This increase in activity can be either excitatory or inhibitory in nature depending on the neurotransmitter involved and which part of the reaction to the drug is taking place. Every area of the brain containing serotonin, dopamine, and/or

    Inhibitory Or Excitatory Potential Changes Graded potentials can be either hyperpolarizations (inhibitory) or depolarizations (excitatory). Inhibitory postsynaptic potential, also referred to as IPSP, is the temporary hyperpolarization of a membrane. An inhibitory postsynaptic potential occurs when synaptic input selectively opens the gates for potassium ions to exit the cell (carrying a positive charge with them) or for the chloride ions to enter the cell (carrying a negative charge

    Part of the Neuron Affected, Inhibitory or Excitatory Potential Changes and Ion Channels Affected by Psilocybin Psilocybin belongs to the classification of drugs called hallucinogens. Hallucinogens typically act by stimulating serotonin receptors at different times or for longer durations than serotonin itself would (Kalat 2004). When psilocybin enters the brain, the enzyme alkaline breaks down one of its phosphate groups through hydrolysis. It then becomes psilocin, an even stronger

    Determining the Water Potential of Potato Tuber Cells I will carry out an investigation that will enable me to determine the water potential of the tested potato tuber cells. Water Potential is the measurement of the tendency of water molecules to move from one place to another. (Ridge 1991) Water always moves down the water potential gradient, therefore moving from an area of higher water potential to an area of lower water potential. Equilibrium is reached when the water potential in one region

    neuron membrane typically has electrochemical polarization potential of 70 millivolts. When the firing impulse comes to the neuron from another neuron via the corresponding synapse (the site of their connection), this polarization potential changes, typically by 1-2 millivolts or less. If the polarization potential decreases beyond the threshold of approximately 60 or 55 millivolts, the neuron fires, otherwise the polarization potential tends to rapidly relax to the original rest level of 70 millivolts

    Lucy and Howard's Potential to Change in Cleopatra's Sister In Cleopatra's Sister, both Lucy, a journalist, and Howard, a paleontologist, represent the culture of the West, they function as cultural authorities of the West. They accept their professions as their identities, which both enables them and limits them in understanding the experience that awaits them in Callimbia, when a newly-founded government takes them hostage. In this essay I will deal with their changes of perceptions, that
