The difference between nature and nurture is that nature is the idea that behavior is effected by your chemical and gene make up while nurture is the idea that you are a blank slate and your behavior is distinguished by experiments. They both effect behavior is what was discovered. * Dualism is supported by cognitive psychologists such as George A. Miller and Sigmund Freud * Rene Descartes dealt with Monism vs. Dualism & Interactive Dualism * Monism is the belief that the mind…

The lab for this week was a rather intriguing, which was appropriate for the very first lab of the semester. What a great way to start off too! Our take home lab tied in nicely with Monday’s lesson on drugs and their impairments on the brain. While I had enjoyed the comedic presentation on such a serious topic – complete with hilarious commentary over disconcerting visuals – it was nice to sit back and skim of the surface of the vast capabilities of the human brain. Admittedly, the information…

The choices I make now as a teenager and not nearly as important as those I will make as an adult. WRONG !!! The choices you make as a teenager greatly influence your ability to choose in your future. Your first choice is to decide which element in your brain will make that choice, emotion or your Intellect. Apparently for teenagers this is not an easy thing to do because, guess what, – our Brains are still developing – we do not yet have the brain capacity to easily make a reasoned choice.…

olfactory tubercle does not possess an association fiber system. The olfactory tubercle receives monosynaptic olfactory input from the pyriform cortex and the olfactory bulb. Axons of the olfactory bulb second order neurons fasciculate to form the lateral olfactory tract that travels along the ventral-lateral aspect of the brain. Axons enter the molecular layer of the olfactory tubercle where they synapse onto olfactory tubercle neurons in the dense cell layer. Mitral cells innervate the…

In this paper I will be discussing many topics about Alzheimer disease. Anyone is at risk of getting Alzheimer's however, some can be more prone to this disease. Alzheimer's has affected millions across the globe including Malcolm Young, the famous australian guitarist, who is currently suffering from this disease. I will be talking about this discovery, cause, symptoms, and effects of Alzheimer's disease. Alzheimer disease has had a huge impact on the United States of America. I will be more…

20 people out of every 100,000 people worldwide have Myasthenia Gravis (Myasthenia Gravis, 2012). Myasthenia Gravis is a disorder that causes skeletal muscle weakness. People experience the worst weakness during periods of activity and the weakness improves under periods of rest. The most common weakness is located in the muscles around the eyes. This causes blurred or double vision in the eyes. It also effects the muscles used in facial expression and chewing. These conditions can cause…

When investigating the mechanisms of neural communication and the impact various drugs can have on this its important to take into consideration what these actually mean and whereabouts in the body are the main components. The word neural communication consists of how neurons communicate with each other through their physiological process, and drugs consist of chemicals, substances or medicines that have a physiological and/or psychological effect on the brain and body. Within this essay I will…

from other neurons and that information is transmitted to the cell body. The cell body may or may not pass the information to other neurons, it makes the decision whether or not to send an electrical impulse. The electrical impulse travels down the axon,…

The intricate reaction between the human’s physiological and psychological responses has been long disputed (Rowbotham, 2001) This ever changing discussion may be explained by the neuromatrix pain theory (Melzack, 1999). However, our understanding of the physiological response to a painful experience and its effects on the body has changed over the years. In the mid-17th century the pain theory was over simplified; nerve impulses travelled to the cerebral cortex in the brain, the more damage the…

Experiment 1 showed the isometric force generated by the ADM muscle of the test subject was able to be measured accurately and quantified into EMG activity as shown in results from Table 1. The established threshold of 2.2mA was used for subsequent increases in stimulation from the threshold to show that more motor units of both Type I and Type II were simultaneously being recruited. The size of the twitch force at 20% above the threshold, 2.6mA, was not a drastic jump as was 40%, 3.2mA, which…
