Somatosensory system

Another defining characteristic of the somatosensory system is its ecological versatility with the ability to detect and process information about a wide range of tactile disturbances (for example, temperature, pain, itching, easily. How does the signal go from brain to skin? Various tactile receptors are attached to many types of nerves. Most receptors use fiber A beta to transmit their signals - they very quickly transmit information. In the brain we receive all types of impulses/information coming from different parts of the body being processed and integrated in the sensory cortex. Signals can be classified by the nature of the receptors (pain, temperature, etc.).” We use information from the sense of touch to tell us about the world…

Introduction Although there has been little research to date involving the somatosensory system and seizures, a group of researcher’s in 2004 conducted a case study involving childhood epilepsy and the possible trigger coming through the somatosensory system. An overview of the case study will be discussed as well as what the somatosensory system is, and how it functions. In addition, the psychological effect on a person who has lived with seizures and the effect it has had on relationships…

Using fMRI, we discovered that several areas in the perisylvian cortex show within-modality adaptation. Interestingly, multiple areas show adaptation to both modalities. For example, parietal operculum (which is primarily somatosensory) and planum temporale (which is primarily auditory) show adaptation properties to both tactile and audio stimuli separately. Their relative response magnitudes were higher to the stimuli that are primarily supposed to process. This result suggests that there are…

Sylvia Plath had a troubled life. She tried to commit suicide once, but failed. She ended up marrying and having two kids, but the marriage ended in divorce. She later tried to commit suicide again, this time she succeeded. As seen in the poem Mirror, if we aren’t content with our reflection or focus too much on finding ourselves through the mirror, we will end up losing ourselves and never find happiness, just like Plath. We need to find ourselves without looking in the mirror, because if…

The purpose of this paper I will describe my initial reaction to the story, respond to four questions pertaining to touch and intimacy, give my interpretation of a spiritual journey with examples and give an analysis to two quotes from the movie Tuesday with Morrie Initial Reaction I have to admit, I had a sigh of relief and actually looked forward to having a different approach with my writing assignment for the week. Initially, although I welcomed the different approach, I was less than…

Our hands are one of our most important tools in regard to communication. We can use them to do a number of things such as gesture express emotion with words, or touch to emphasize our words, or even using emblems, which convey a message without the use of any words. We almost rely on our words, and some of us can not even talk without using our hands. Most of us use our hands every day without even noticing. A good example of this is in class, we raise our hands to indicate we have a question…

State projection of Layer V of the Primary Somatosensory Cortex (1pt) Layer V projects to the dorsal column nuclei, as well as to the dorsal horn of the spinal cord; and to the striatum and brain stem in general. 15. What is the pathway of the projections of the Secondary Somatosensory Cortex (SII)? (1pts) Projects to the Insula which then projects to amygdala and hippocampus. 16. How the chemicals which released during tissue damage sensitized nociceptors? (1pt) Act to either decrease the…

For instance, there is a distorted sensory representation in the brain. Outputs from touch receptors in the fingers/ facial areas occupy more space on the somatosensory cortex, so perhaps more brain power is spent interpreting the sensations of touch from the fingers/face compared to the rest of the body. In our conversation I also brought up an image that depicted the somatosensory representation of our body across the cortex. They were amazed to see how distorted/uneven the actual…

Short Story Journal - “Choices” by Susan Kerslake Every professional and amateur writer tends to use imagery to paint a picture, to connect the five senses with the story. The majority of the time it is employ to evoke emotion, mood. Authors utilize imagery to get people involved in the story, and to acquire them to reflect. It makes the reader visualized a vivid picture of what the writer is trying to convey. The majority of the people tend to relate as well as to obtain familiarity with the…

Around eight o’clock one October night, my life was changed forever. A senior in high school, I was leaving the county fair, after having spent the evening with friends and family, enjoying one of the many “lasts” of my high school experience. I was stopped at a red light in front of my best friend when suddenly all I saw was white light and all I could hear was the screeching of tires and my own loud screaming. The bright, flashing lights of emergency vehicles and the feeling of being jerked…
