Brain Response of Behavior

The communication process of nerve cells in the sensation is a complex electro chemic process from iodin neuron to the next in a series of chemic reaction to pass the sum (Charles, 2002). However, the pass along to be passed precedes the process of communication involved. The core to be communicated to the brain neurons originates from the senses of sight, touch, taste, smell and sound.The neurons dendrites ordinarily receive a chemical nitty-gritty from the neighboring neuron which generates or triggers off a chemical reaction to form nerve impulse.The generated nerve impulse or action potential travels down the neuron tube referred to as axon through the borderinal button at the end of that neuron. At this end, the depicted object carried is passed to the next adjacent neuron through a synapse. However, the synapse has a gap called synaptic cleft that sum neurotransmitters should diffuse through to the next nerve cells dendrites. The electrical message to be easy throu gh synaptic cleft is contained in synaptic vesicles with several neurotransmitters.The neurotransmitters on the presynaptic neuron or neuron that has the message to diffuse through synaptic cleft to the postsynaptic neuron or on the receiving neuron mustiness be in appropriate key and fit complex body split (Charles, 2002, p. 63). This is necessary to enhance successful neurotransmitters binding after diffusion. Once the neurotransmitters are diffused through the synaptic cleft, they bind to the dendrites of postsynaptic neuron and release the chemical message that triggers off or stimulates neuron chemical changes.Thereafter, the process repeats as the previous single for this neuron until it moves message to the next nerve cell and communication enhanced. It is a point of worth to note that, once message diffuses through the synaptic cleft to the postsynaptic neuron, on that point are several neurons that shall receive the message but sole(prenominal) specific neuron that i s compatible to the message is shall successfully receive and pass it by to the next neuron.For slip, if there is need for body temperature control, the neurons that are specialized in body temperature control messaging only shall despatch communication to the brain and after interpretation by the brain the same neurons shall carry message to the hypothalamus. because hypothalamus gland shall release hormones to increase liver activities, constriction or vasodilatation of blood vessel, follicle hair behavior and individualised behavior to respond to cold by warming or wearing heavy clothes or hot weather by wearing light clothing (Albert, 2002).Neurotransmitters and their effect on behavior The noticeable behavior is a result of brain interpretation and stimulated action course. However, it should be noted that the brain ability to influence behavior is highly dependant on neurotransmitters contained in the synaptic vesicle. The neurotransmitters have the efficiency to influen ce the message being passed and the outcome in terms of behavior exhibited. In this regard, neurotransmitters are chemical agent in the neurons that are responsible for facilitating message movement from one neuron to the adjacent one through axon (Charles, 2002).To this effect, neurotransmitters are either excitatory which allows communication or inhibitory that hinders information release depending on the nature of message being passed on. But effects of neurotransmitters whether inhibitory or excitatory are different depending on the nature or receptor. Some common examples of neurotransmitters are Acetylcholine which is an excitatory neurotransmitter dealing with the muscular tissue tissues especially the heart muscles to facilitate blood pumping mechanism.Epinephrine is concerned with competency provision for urgent confrontation such as immediate flight or fight by producing glucose as a ready energy to an individual. Another neurotransmitter is the Serotonin which is conc erned with persons mood and insufficient leads to mood disorders such as depression and anxiety disorders. Oxytocin is concerned with maternal related behaviors such as mammary glands, sperm production and ovary release in sexual related behaviors. On contrary to excitatory neurotransmitters, Dopamine is an example of exhibitory neurotransmitter that inhibits action potential in motor neuron.Abnormal quantity of Dopamine results to Parkinsons disease and substance attachment (Charles, 2002 Albert, 2002). Part II major regions of the brain and their functions on behavior The brain is a complex structure that is divided into specialized posts or regions that perform specialized function. The importance of specialization and brain parts division is not only in brain processing information and generating responses, but the specific sham on behavior of an individual generated by each specialized part. In this regard, the brain has three chief(prenominal) regions rational cortex, li mbic system and the brain stem (Charles, 2002).The brain stem is the most primitive part of the brain that is located at the joint where the spinal cord enters the brain (Charles, 2002). This part of the brain contains such sub-parts as reticular activity system, medulla and the Pons. The main function of this part of the brain is for autonomic functions deemed as necessary for survival such as health, food, shelter and security seeking behaviors. For instance, when a person go ill, the brain stem triggers off the course of action to seek medication or health care, thereof such an individual shall move towards the hospital premises than to any other direction of food or security.The cerebral cortex is brain region that is on outer part that covers the brain (Charles, 2002). By integrity of covering the brain, the cerebral cortex is considered as the largest part of the brain. The behavioral function of the cerebral cortex involves high cognitive processes such as memory process that enhances language, thought and learning. Therefore, behaviors such as performance in academic work, ability to retain and remember, verbal fluency and speech development are controlled and generated by the cerebral cortex.Limbic system (Charles, 2002) is the third region of the brain with structures such as genus Hippocampus, thalamus, amygdale and hypothalamus. This part of the brain is responsible for emotional related behaviors of individuals such as motivation, memory functions, and physiological functions. For instance, amygdale is responsible for behaviors such as anger, fear and aggression. The hippocampus sub-structure involves the functions of memory such as information coding and processing into short term and long term memories. Hypothalamus is responsible for emotional behaviors such as hunger, sexual feelings, thirsty and reproduction behaviors.
