Elements 1 Neurons: The Basic Elements of Behavior Introduction to Psychology 101 Elements 2 The Basic Elements of Behavior The human body is a tremendous creation that is quite capable of performing a multitude of multifaceted movements and thoughts. In addition to its’ ability to move and think‚ the human body also allows numerous senses to become involved throughout ones daily routine. A person’s ability to think‚ remember‚ and experience emotion are all results of the body’s

of the body. Neuron: the basic cell that makes up the nervous system and that receives and sends messages within that system. Dendrites: branchlike structures that receive messages from other neurons. Soma: the cell body of the neuron responsible for maintaining the life of the cell. Axon: tubelike structure that carries the neural message. Glial cells grey fatty cells that provide support for the neurons to grow on and around‚ deliver nutrients to neurons‚ produce myelin to coat axons‚ clean up waste

Neurons are perhaps the most important part of the human body‚ and while they are a vital part to our lives on a daily basis‚ many don’t recognize the significance they play‚ and have little to no idea how they work. In order to demonstrate just how important these neurons are to our survival‚ I will show you why and how these remarkable‚ microscopic pieces work. In doing so‚ you’ll be able to fully understand one of the human bodies most critical biological features. Neurons are the essential tools

A neuron is a nerve cell in the brain‚ it is essentially the building block of the nervous system. Each neuron is itself a miniature decision making device‚ reacting to signals it receives from hundreds‚ even thousands of other neurons. Each signal is either excitatory or inhibitory. Excitatory signals increase the likelihood of an action potential happening‚ inhibitory make an action potential in a nerve cell less likely. The action potential is a nerve impulse. Once the excitatory signals over

summation Summation can be defined as the method which neurons use to communicate with each other‚ determining if the cumulative postsynaptic potential in the neuron is enough to pass the threshold for firing. There are two types of summation‚ spatial summation and temporal summation. Both types of summation are similar in that they work to strengthen the EPSP of a neuron‚ meaning they help create more postsynaptic potential so that neurons are more likely to fire. Spatial summation and temporal

Neurons‚ the Basic Elements of Behavior PSY 101 16 January 2011 One of the most basic yet complex systems in the universe is the biological organism‚ with even the simplest person being considered the most intricate and advanced biological entity alive. Each person’s actions are controlled by the brain‚ which when broken down to the simplest explanation is essentially the most advanced computer in the world and just like a standard home computer the brain is made up of several pieces to function

Mirror neurons are defined as a group of neurons that fire both when the monkey executes a motor act and when it observes another individual (a human being or another monkey) performing the same or a similar motor act. They were discovered by a group of scientist at the University of Parma‚ Italy‚ when working on monkeys. The researchers‚ led by Giacomo Rizzolatti‚ had observed strange phenomenon with peanuts. They discovered that same group of neurons was responding when the monkey would pick up

The Messenger 1. The Envelope on p.118 contains an ace of clubs and a letter. What do we learn about the fate of ‘Mr Edgar St’? We learn that ‘Mr Edgar St’ has gotten on a train and left the town. 2. What is written on the ace of clubs? On the ace of clubs it says; say a prayer at the stones of home. 3. How did Ed end up at the river near his home? The guy that hopped into his taxi led him there and refused to pay‚ so Ed gave chase. 4. What is written on the rocks? There were

subject of mirror neurons‚ which are neurons that fire when an animal acts or observes the same action done by another. We learned that these neurons exist primarily in the ventral premotor cortex F5 areas of a monkey’s brain. Experiments proved that neurons in the VPC F5 area fire when a monkey does an action‚ but also fire when a monkey watches a human do the same action. However‚ when the monkey watches the human just carry out the motions of the action‚ not actually do it‚ the neurons in this area

While neuron disorders are debilitating diseases‚ scientists are researching promising new cures. This research ranges from the crosstalk between motor and sensory neurons‚ to the morphing of skin cells‚ and the function of the CLP1 gene and its role in certain diseases. A first example of this promising new research is that scientists have discovered that ephrin and Eph prevent spinal cord neurons from regenerating after injuries. This means that if scientists can coax the neurons that are injured
