How Neurons Communicate With Each Other Through Electrical...

1. Describe how neurons communicate with each other through electrical and chemical processes. Neurons communicate with each other through an electrochemical process in three steps (Stufflebeam, 2008). An electrical impulse will travel down the axon to axon terminals. This causes the vesicles to open and neurotransmitter molecules are released into the synaptic gap. Neurotransmitter molecules then cross the synaptic gap and enters the receptor sites located on the dendrites of the receiving neuron. The information is carried along axons and dendrites because of changes in electrical properties which we call action potential. An action potential is initiated when a messenger attaches itself to a receptor. This occurrence causes an electrical signal to be triggered and is generated through the neuron. Once the signal reaches the end of an axon, which is at the end of a neuron, a neurotransmitter molecule will return to the synaptic gap where they are received by the sending neuron and the process is repeated or are destroyed by enzymes (Griggs, 2014, p. 41-45). 2. The media talks about a popular class of psychopharmacology drugs called the SSRI’s. You may know someone currently taking one of these medications because they are frequently used for treating mood disorders such as depression. Please list and describe the neurotransmitters that are being targeted by the drugs and how these drugs work.

What happens when damage to the brain occurs? How does it rewire itself to process information or learn new activities?. Damage to each hemisphere of the brain has different effects on the way individuals learn since each hemisphere is in charge of different functions. Furthermore, the brain processes information differently according to a person’s learning style. First, Let us explore on the functions of each hemisphere of the brain and how it worksRead MoreThe Biological Aspects of Psychology950 Words   |  4 Pages Biological Psychology: The study of the cells and organs of the body + the phys/chem changes in behavior + mental processes. †¢ Behaviours and mental processes influenced by biology, biological processes by environment as well Nervous system : Complex combination of cells that mainly function to let an organism gain information about what is going on inside/outside body and how to respond to it.

Neurons are the elementary components of the nervous system, the body s speedy electrochemical information system. A neuron receives signals through the branching dendrites, and sends signals through its axons. Some axons are encased in a myelin sheath, which enables faster transmission. If the combined receive signals exceed a minimum threshold, the neuron fires, transmitting an electrical impulse (action potential) downRead MoreChapter 4 : Neurons, Hormones, And The Brain1699 Words   |  7 PagesPatrick Beninga Professor Hanretty PSY 202 Section 16 7 October 2015 Chapter 4: Neurons, Hormones, and the Brain The Nervous System: A Basic Blueprint The Central Nervous System Central Nervous System The par of the nervous system consisting of the brain and the spinal cord interprets information about the senses ex: Touch, Taste, Sound, Smell.

The relationship between biology and psychology is a ‘give-and-take’, shared relationship where one can be used to explain and provide insight into the other, as both are related to the physical body and the mind. For that reason biology holds a much significant and important role in the study of psychology.

Neurons are important part of the nervous system, which has the responsibility for transmitting electrical and chemical signals in the entire body (Stufflebeam, 2008). Neurons are required to demonstrate qualities of ability to respond to stimuli, being conductive, and ability of secreting chemicals.

The cerebrum is situated at the back of the brain. The cerebrum is divided into two cerebral hemispheres, left and right. It also consists of the corpus, callosm, and nerve fibers. The left and right hemispheres communicate with each other. The brain stem â€Å"connects the brain to the spinal cord† (Lu Bludua, 2011), which regulates the body. The cerebellum is positioned beneath the cerebrum. It manages a person’s equilibrium and coordination.

The brain is a unique organ, it allows us as humans, for example to imagine, speak and perform a lot more complex functions. To function well as a complex organ, the brain has a lot of cells. The brain consists of neurones and glia cells. Neurones observe changes from the environment, communicate these changes to other neurones and issue commands to the body to react on these changes. Glia cells give the neurones among other things protectionRead MoreHypothalamus Gains Admittance Essays1106 Words   |  5 Pagesof numerous important bodily functions. The hypothalamus is shaped like a cone and ends in the pituitary stalk, a part of the pituitary gland.
