The sensory process begins as the ear senses the crack of the bat as it strikes the ball. The information received by the ear is received by the temporal lobe which alerts that an action has taken place which begins the transmission of neural messaging. Next, a dendrite at the receiving end of neuron cell will take the initial transmission and carry it forward to the body of the cell. Once the dendrite has received enough information the process will continue by undergoing a nerve impulse sending the message across the synaptic cleft to be received by the neighboring neuron. The message will now bind with the receptor site and should the receptor and neurotransmitter fit properly the message will then continue to the next phase (Morris & Maisto, 2005).

In the second phase of the scenario the ball is seen coming towards the individual. As the occipital lobe processes this information the process is repeated of transmitting information from one cell to another. Information will once again be transmitted from one cell to another. When this phase is complete the final phase begins (Morris & Maisto, 2005).

The response to reach out and catch the ball occurs in this final phase of the scenario as successfully transmitted messages in earlier phases trigger this response. Now the frontal lobe receives the previously processed information and begins to prepare for future movement. The frontal lobe plays a significant role during this phase as this is the area responsible for voluntary action which allows the body to respond to the messages being received. The final message is sent producing an almost reflexive response to reach out and catch the ball with the glove (Morris & Maisto, 2005).

During this scenario multiple occurrences of transmission of information have taken place. While the scenario likely began and completed itself in a matter of only seconds countless transmissions have gone from one region of the brain to another. In the event any of these...

    ..."Sensory Perceptions" I believe that you can trust your personal interpretation of sensory data to give you an accurate view of the world. Other people may have a different opinion and believe that you cannot trust your personal interpretation of sensory data to give you an accurate view of the world. Our senses act as or lenses, amplifiers, particle detectors, and pressure and heat gauges. These sensors are acutely sensitive. Our hearing reacts to a sound vibrating in frequency as high as 20, 000cylecs per second and to multitude of timbres that allow it to recognize different human voices. Our site can detect a candle flame in the dark, clear night 20 miles away or discern a single color (mauve or teal) out of millions of hues. Our sense of smell can detect the single molecule of bacon or coffee out of five billion molecules. Our senses feed our brain much as food feeds our body: without their input, our brains will be almost empty (Gary R. Kirby and Jeffery R. Goodpaster 2007, Thinking, Fourth Edition). The stimuli detected by our senses can be either deliberately ignored, in which case they disappear almost instantaneously, or perceived, in which case they enter our sensory memory. This does not require any conscious attention and, indeed, is usually considered to be totally outside of conscious control. The brain is designed to only process information that will be useful at a later date, and to allow...

  • Emotional and Sensory Memory Essay

    ...Emotional and Factual Recall: The Effects of Damaging the Hippocampus and the Amygdala In recent studies, psychological physiologists have been able to identify the effects of certain brain damage on both one’s emotional memory and sensory memory. Two areas of the brain that have been studied are the amygdala and hippocampus. Studies on animals have shown that damage onto the amygdala effects emotional conditioning, while damage to the hippocampus eliminates the ability to establish certain knowledge and learning abilities. The effects of damage on to the hippocampus and amygdala in humans had not been sufficiently study until Anotonie Bechara began an experiment testing the effects of these damages on humans in 1995. By using Skin Conductance Responses (SCR) and a type of memory test, Bechara administrated two types of experiments: auditory-auditory and visual-auditory, on participants that had damage to the hippocampus and/or the amygdala. The two experiments are similar, only changing the controlled stimuli. SCR measures electrical resistance as changes in emotional arousal take place by monitoring the activity of the autonomic nervous system. SCR is connected to patient’s skin and can continually measure the change in emotion in the participants. Though SCR can measure emotion, there is no way in defining what emotion one is feeling through SCR. Bechara chose three participants that had damage to the brain, while having four participants...

    ...Assignment 1: Sensory Perceptions Nicole Brock PHI 210 Renee Pistone 10/21/2012 “The brain, a complex structure, allows a human being to perceive and react to their environment, contemplate "the big questions," and experience a myriad of emotions. The brain controls the body and maintains the delicate internal balance needed to sustain life” (Smith, 2010). If fortunate enough, we humans all have five senses: vision, hearing, taste, touch, and smell. All of these senses that we have, work together to give us a conscientious picture of the world and where we belong in it. The statement, “There is nothing in the mind unless it is first in the senses” (Kirby & Goodpaster, pg. 54), means, that our brain would be empty without our senses. Our senses consolidate to make us understand who we are, where we are, and what is happening around us. Because our brain feeds and processes information about our five senses, we put meaning to our sensory experiences, thus, we are able to respond and behave accordingly. We rely on accurate observations. Our senses prove its accuracy on a daily basis and “act as our lenses, amplifiers, particle detectors, and pressure and heat gauges” (Kirby & Goodpaster, pg. 54). Our vision allows us to be aware so we can stop at red lights, wait for cars to pass, and know when it is safe to walk across the street. Hearing is another powerful sense that we use to listen to words, is crucial in...

  • Sensory System Essay

    ...Essay 3 Shubham Tyagi How do our sensory systems work?  Write about taste, sight, hearing and touch. Introduction Sensory systems are important to us; they let us perceive the environment. The senses can be broadly divided in to the sense of touch, smell, taste, vision and hearing. The seemingly simple perception is in fact not as simple as it sounds there is a lot of chemistry and physics that takes place. When we touch a hot surface, smell that delicious food, see beautiful colors, or hearing that beautiful music, our nervous system is working at an incredible rate, to make sense of these signals and let us enjoy them or run away from them. Sense of Taste: Sense of taste is related to the sense of smell but there are only five kinds of tastes that we can detect. They are sweet, sour, bitter, salty and umami. Detection of taste is done via special epithelial cells in the taste buds of the tongue. In case of salty taste the sodium ions leads to opening of ion channels and the signal is sent as an electrical impulse to the brain. In case of sweet, bitter an umami 7TM receptors are involved, when a “tastent “ binds to these receptors they produce cAMP, which in turn open channel proteins which allow ions to pass through and the neuron send the impulse to the brain which...

    ...Outline the main causes of sensory loss There are many factors that can be attributable to causing sensory loss. Varying degrees of vision and hearing loss may occur: During pregnancy: a woman may come into contact with a virus or disease that affects the growing foetus an inherited condition or syndrome may be passed on to the child a chromosomal disorder may occur during the foetus’ early development injury affecting the foetus whilst in utero Complications at birth (multiple health and physical conditions may also be present): a child may be born prematurely neurological conditions as a result of a traumatic birth or lack of oxygen Post natal/childhood: inherited conditions that may present during developmental stages auto immune conditions illness cause by virus or disease injury to the eyes and ears acquired brain injury Young adult to older age: inherited conditions or syndromes that present later in the person’s life non-hereditary conditions and syndromes auto immune conditions illness cause by virus or disease injury to the eyes and ears acquired brain injury the ageing process 4.2 Explain where additional advice and support can be sourced in relation to sensory loss Individual care plan As part of the assessment, the specialist will identify the person's individual needs and requirements which will form a key part of...

  • Sensory Perception Essay

    ...Assignment 1- Sensory Perceptions Assignment 1: Sensory Perceptions 1. Provide at least three reasons for believing in the accuracy or inaccuracy of sensory information. Our senses are who we are, without them we are left to isolation and our ability to think and learn due to lack of experience. Senses are our connection from the physical world into the realm of our mind. “There is nothing in the mind unless it is first in the senses” (Kirby & Goodpaster, 2007, pg. 54) Many ancient philosophers described our senses as “the windows of the soul” (“Human Sensory Reception”, 2012) Each of our senses work together and form a composite picture of who we are, where we are, and what is going on around us. Our sensing and thinking are closely connected and we rely on accurate observations. I believe that our senses in most cases are accurate. There are factors in life such as being sick, sleep deprived, or exhausted that may skew the accuracy of our sensory perceptions temporarily, but in most cases they are accurate and the information they provide us with is vital in grounding our thinking. There are also other cases where what we think we see is not really what it is, “habits, interests, and biases, focuses and thus limits our perceptions.” (Kirby & Goodpaster, 2007, pg. 56) I believe that our sensory information in most regards is accurate, without any sort...

  • Sensory Perceptions Essay

    ... Sensing has been the foundation for our lives since before birth. It is a safe assumption that sensing shapes the world around us and helps us to synthesize information. The unique thing about sensing is that no two people will have identical thoughts or perceptions; hence, the innumerous possibilities of sensory output. Although the senses are the foundation of our beings, there are instances when we must question the accuracy/inaccuracy of sensory information. Below I will attempt to explain the instances when sensory information can be deceptive and/or receptive. There are three reasons in which we can believe in the inaccuracy of sensory information. First, we are all unique individuals; and no two people perceive things in the same context. I’m reminded of a drawing of an old woman and a young woman. When some people look at the drawing they see the young woman while others see the old woman. This is because our interpretations of what we see are determined by how we process what we see. Some people may see the minutest instances of detail while others see the larger scale. Perceptions are driven by the senses but the senses have to be working effectively to aid in visual stimulation. The second way that we are deceived by our senses is by one’s own cognitive ability. Cognition enables us to solve problems, communicate, learn new information, and know the world around us....

  • Sensory Perception Essay

    ...stimulate varied emotions. As we generally connect the sounds we hear back to our memory, meaning we can recognize a person with a distinguishable voice. The sense of smell is important and is often used subconsciously for instinctual reasons. As recently discovered the extent to which the smell of a partner can affect our attraction to them. Our perceptions and evaluations others are influenced by their smell, as unpleasant smells connect to our disgusts or negative opinion of another. However, the perception of what is a good or bad smell can be interpreted differently between people as it is attached to previous knowledge gained. Knowledge, justification and critical thinking are three factors that contribute to the accuracy of sensory data (Mohanan, 2000). Critical thinking is the mental process of reflecting upon something to assess its credibility, truth, significance, usefulness, value or goodness on the basis of information available to us and a mode of justification that we consider legitimate. Critical thinking, knowledge and justification support the accuracy of information that our senses feed our brain. What we call knowledge is a collection of propositions that we believe to be true. A knowledge claim becomes part of the knowledge for an individual when the claim is accepted as true. Justification involves providing reasons for accepting propositions that we regards as knowledge, that is, for considering them to be true. It also...
