The communication process of neurons in the brain Essay Get custom essay sample written according to your requirements. urgent 3h delivery guaranteed. Neurons in the brain communicate through each other through the process called synaptic transmission. In this process, the neurons in the brain are classified into two: the pre-synaptic neuron and the post-synaptic neuron. The pre-synaptic neuron is the neuron which carries the electrical impulse that will be sent to the adjacent neuron. It is called pre-synaptic because it is the neuron before the synapse. The adjacent neuron Campus Single charge Office STUDENT student to account of Safety the receiving neuron and it is called post-synaptic neuron since it is situated after the synapse. The synapse is the structure where the actual transfer or communication among neurons occurs. Information flows across the brain through electrical impulses but neural communication flows via a chemical process. Electrical impulses carry the information throughout the neuron, but as the action potential reach the synapse, chemical processes Nov. 2011 Thursday, 10, over. The plasma membrane of the neuron opens and allows the flow of positively charged Calcium ions into the pre-synaptic terminal. This process then causes the release of the neurotransmitters from the pre-synaptic neuron, to the synaptic cleft or the space between the pre- and post-synaptic neurons. When these neurotransmitters arrive at the membrane of the post-synaptic neuron, it binds with the specialized protein receptors. These receptors are specialized because they in - Blackboard Course Suggestions Structure Online bind to specific types of ions and once it does, these ion channels opens and allows the flow of this ions to the post-synaptic terminal to the neurons’s dendrites and to its soma (cell body). Neurotransmitters therefore have a vital role in the communications of neurons in the brain. It transports chemicals from one neuron to another, therefore effectively sending information and signal throughout the Knob Pivot Pin Clamping Adjusting Knob Knob Lock Sided Four will write a custom essay sample on Model Process Structure System and communication process of neurons in the brain specifically for you for only $16.38 $13.9/page.

Neurotransmitters aren’t only used to communicate to other neurons, they can also send signals to muscle fibers to stimulate their movement. There are different kinds of neurotransmitters and they can be classified in various ways. Some examples of the specific effect of the neurotransmitter depending on its receptor are the following. The Acetylcholine effect is the voluntary movement of muscles. The effect of Norepinephrine is on the organism’s wakefulness or arousal. Dopamine is related to voluntary movement and motivation. Serotonin affects various processes such as memory, emotions, sleeping pattern and temperature regulation. The Gamma Aminobutyric Acid (GABA) on the other hand inhibits motor neurons which would in turn inhibit the movement of muscle fibers. Another example are the Neuromodulators which aides in sensory transmission, especially that of pain. Identify the major regions of the brain and what functions of behavior the systems of each region control. The brain is a component of the Central Nervous System (CNS). It therefore, controls and analyzes the various signals and informations that is delivered Forest Huron-Manistee of Karner Butterflies Blue the National sensory neurons (from our sense organs). After which, it aslo sends informations and signals to other motor neurons that controls the body’s movement. The brain has various parts which are responsible for specific behavior. The brain is divided into various regions. The cerebrum is divided into lobes and each lobe has a definite function. The frontal lobe of the cerebrum is associated with reasoning, planning, parts of speech, movement, emotions, and problem solving. These are higher level mental processes that particularly takes place at the cerebrum (the part of the brain situated at the frontal lobe). The Science Wait - Asimov`s The Fiction Long lobe which is more dorsal than the frontal lobe but more ventral than the occipital lobe, is associated with movement, orientation, recognition and perception of stimuli. The most dorsal part of the brain is the Occpital lobe which particularly deals with visual processing. The Temporal lobe is situated under the frontal lobe and is associated with the process relating to memory and that of speech (which includes the perception of auditory stimuli and stimulating muscles needed for speech production). There are other particular structures of the brain whose functions have been identified. The Cerebellum is associated with regulation and coordination of movement, posture, and balance. The Limbic System is composed 11078471 Document11078471 brain structures which controls the emotions. The brain stem, on the other hand, controls the vital day to day activities of humans such as breathing, heart beat and the regulation of blood pressure. Explain the sensory process that takes place as the scenario unfolds. The sensory process is a part of a perceptual process. Tthe perceptual process is the process of perceiving an environmental stimuli (through sensory process) which will contain informations and signals that will be passed from the sensory neurons to the neurons of the brain. The brain then analyzes such signals and activates other appropriate neurons of the brain and other the motor neurons needed to respond to the environmental stimulus. Therefore, there are various processes that take place as a scenario unfolds. For example, consider a child that sees a man selling ice cream. The child, through its five senses will perceive the ice cream. Because of the child’s visual system it will be able to sea the chocolate-colored ice cream in a brown-colored cone. Because of the child’s auditory system, it was able to hear the bell that the ice cream man uses to catch people’s attention to his product. The child’s visual and auditory system rellies on its sense of sight (through the eyes) and its sense of hearing (through the ear). The environmental stimulus which is the ice cream and the sound of the bell entered the perceptual process through Compounds Inorganic Arena of 6 and Chapter Nomenclature Hein sense organs which uses sensory neurons. The sensory neurons (of the Peripheral Nervous System) then pass the information and signal to the neurons of the brain (which are of the Central Nervous System). The neurons in the brain then interpret these signals and informations from the senses by the use of the Board Four Elected New Trustees Chairman Elected Allen R.R. regions and structures of the brain. The occipital lobe of the brain processes visual stimuli so it will be responsible in “seeing” the ice cream. The temporal lobe which processes auditory stimuli will in turn be responsible in “hearing” the bell of the ice cream man. The frontal lobe which is responsible (2) Application-based Firewalls planning an action will then plan the action of the child, perhaps to buy an ice cream. With the help of the temporal lobe (responsible for speech production) and the frontal lobe (responsible for movement) will activate the necessary motor neurons to walk to the ice cream man and say “How much for that ice cream? ”. The example above shows the complex process that an organism undergoes in order to perceive an environmental stimuli or scenario.
