Welcome. You are going to collaborate and create a discussion over biochemistry and nuclear chemistry, with the help of your classmates. Over the next few weeks you are going to use this blog to answer questions such as:
What is it? Who uses it? Why is it important?
You are also going to learn about current research and developments in the field. Find exciting examples of basic and applied research, add images and video and be creative.
I will monitor your comments and redirect as needed.
The science of how emotions are produced and how they react function in each person has been debated for generations. Some scientists believe that having and feeling emotions is an essential human trait. They can be necessary as survival in the world but also in social context. Understanding how emotions come about can be essential to occupations such as Psychology, Sociology, and Psychiatry. Emotions are a body-wide release of all kinds of emotions that carry molecules to areas of the body that often don’t have electrical neurons. These chemical, known as ligands, travel through extra-cellular fluids and hookup with highly selective receptors located on cells. Thoughts and emotions cause distinct neuron-firing patterns within various parts of the brain. These patterns coincide with chemical releases and reactions in the body. One of the more recent theories established in the 1960’s on how emotions work is The Schacter-Singer Model. In the model they explain how conscious mental processing and physical change are both necessary to feel emotions. An example of this is how the cause of your heart rate to increase can be interpreted by your brain as fear. The same physical responses can be interpreted different ways and then labeled as different emotions. For example, if your heart rate increases, it can either be interpreted as fear or excitement, even though it’s the same physical reaction. A recent study has been made on male prisoners between the ages of 18 and 50. They first tested these individual with the Hare Psychopathy Checklist to establish if they met the criteria of a psychopath, then they ran scan on their brains while showing them violents stimuli (such as videos on someone being intentionally harmed or pictures of people in pain). The diagnosed psychopaths scans with different from those determined not to be psychopaths. In the scans of the psychopaths, scientists saw that certain regions of the brain, including the orbitofrontal cortex and the ventromedial prefrontal cortex, were less active than the others. These parts of the brain are known for evaluating consequences and weighing decisions. They also noticed that the insula, a part of the brain that plays a role in emotional awareness, had greater activation. With this information, they determined that psychopaths are aware of other’s pain but the signal just doesn’t register in other parts of the brain, this explains their lack of empathy and insensitivity.
