Cells Interacting: Astrocytoma in its cancerous form is a situation in which a malignant tumor starts in Astrocyte cells, which have the purpose of protecting nerve cells. As the tumor grows invasively into these cells, it presses on the nerve cells and other parts of the brain. Cancerous astrocytoma will grow very quickly, spreading into other sections of brain tissue. As it does this, it will start to push on the brain itself and stop it from functioning properly. …. Function: The…

neurotransmitters, dopaminergic signaling entails an equilibrium between dopamine release and the re-uptake by presynaptic nerve terminal. Under specific circumstances, a stimulus will promote the release of dopamine into the synapse. Dopamine transporters will then remove the dopamine from the synapse so that vesicular monoamine transporters can store the neurotransmitter into vesicles, release it, and protect it from oxidation (Riddle et al, 2006). Damages in dopamine transporters or the…

Anatomy of cerebral cortex: Brain is most complex organ in human body. The ability of brain for its functioning normally is manifestation of various activities it takes participation in various activities of day to day life, being it hidden from the view or perceptible, like walking, smelling, thinking, laughing, speaking, and hearing. These manifestations are results of very coordinated and complex electrical and chemical activity within and between the cells those makes up our brain. Abnormal…

away who you are as a person. Alzheimer’s takes away the personality and memory of a person with the disease. The symptoms of Alzheimer’s begin when the synapses are disrupted. Plaque forms between nerve cells and blocks communication. Neurons in the brain cannot connect and synapses disappear. Not only does Alzheimer’s disease affect the synapses in the brain, it also attacks the hippocampus, which is the main component of memory, and new memories cannot form. 2.) The genes that may be…

Brain Development Length The human body it’s in a constant change and development, physical and intellectual development from the conception until it dies. Besides the heart, the brain is considered the most important organ of our body. The brain starts its development from the nine to sixteen week of gestation and it continues growing and improving through the time and experiences. The brain development starts very fast in the infancy and becomes slower through the lifespan. In the first months…

drugs might not always work, side effects of the drugs may be harsh, could harm the body in the long run. 6. Describe how a drug can alter behavior at the level of the synapse. A drug could alter behavior at the level of the synapse because that is where chemical information is exchanged between one synapse to the other. The synapses have receptors on them and the response of the drug depends on which receptor it binds to. Each receptor has its own response to a very specific drug. These…

Adolescents, the age in which young people are still building up their reasoning and are most abnormal among all ages. While other Western nations rarely convict minors as adults, the rate of teenagers receives adult sentence in the United States is quite high compared to other countries. This creates two different opinions about the issue. One side argues that juvenile should not be charged as an adult no matter what crime juveniles commit. The other side, however, disagrees as they insist that…

Excitatory ion channel synapses have neuroreceptors that are Na+ channels, when Na+ channels open, depolarisation takes place. However inhibitory ion channels consist of neuroreceptors that are Cl- channels, when the chlorine anion channels open, hyperpolarisation takes place, making action potential unlikely. Non channel synapses - neuroreceptors are enzymes that are bound to the membrane. When activated, they catalyse (cause…

space between a neuron’s axon and another neuron’s dendrites is called a synapse (Scholastic). If a synapse is not being used it is pruned or gets removed through synaptic pruning (Scholastic). That energy being used on that synapse is re-directed into a more active synapse (Scholastic). Synaptic pruning occurs based on choices of activities and teen’s behaviors (Scholastic). If teens are online all the time, then synapses that the teen’s need is being pruned away due to being online all the…

purpose of psychology is to “study only the relationship between experience and behavior” while neuroscience aims at explaining experience’s influence on memory by examining the “brain systems, synapses, and molecules” (5). According to Rudy, memory is reducible from brain systems to synapses and from synapses to molecules and chemistry. As such, the purpose of neuroscience is to “relate the basic facts about memory to events that are happening in the brain” (Rudy…
