The Challenge of Determining Consciousness

Consciousness is a state of awareness of self and the environment and is determined by the level and content of this awareness, also referred to as arousal and awareness respectively (1). Consciousness itself takes many forms, as can be seen in the many combinations of level and content of awareness. When describing comas and vegetative states, people often use the terms interchangeably and freely without regard for the differences in consciousness of patients in these states. This however does not account for the differences in consciousness of patients in these states. In a coma, a patient is described as having “disordered arousal,” as opposed to an impairment of the content of consciousness (as is found in patients in minimally conscious states).

Conversion Disorder: An Analysis of the Hysterical

Historically termed “hysteria” and thought to be a physical manifestation of disordered emotions, little is known about the mystery that is conversion disorder (5). In the seventeenth century, some individuals with unexplained paralysis, blindness or “fits” (seizures) were thought to have been involved with witchcraft and were burned at the stake (2). Nowadays, these symptoms are considered relatively common and oftentimes debilitating. Although not much is known about conversion disorder, it seems possible that the neurological processes responsible for its development are related to those involved in anxiety and depression disorders.

Language’s Relationship to the Brain

            As someone who is studying in Japanese at Haverford College, I have always found language and its relationship with the brain interesting. I have always wondered what gives humans the ability to comprehend language and I have always wondered how this ability is different from any other animal’s ability to interpret sound. I have additionally wondered how the ability to hear could affect language comprehension. In other words, is having that “input mechanism” really necessary for understanding and creating spoken language?

Scents Sense: Olfaction, Memory and the Capabilities of the Brain

 The human nervous system is made up of three overall types of neuronal connections. These connections link sensory neurons to the rest of the nervous system, the nervous system to motor neurons, or neurons within the nervous system to other neurons in the nervous system. Inter-neuronal connections are by far the most numerous of all connections in the nervous system, while sensory neuron connections are relatively sparse. Because of this disproportionate number of connection types, it is essential that the human brain be able to derive complex reactions from very few sensory inputs. The link between olfaction and memory provides a truly remarkable example of this ability. Olfa

Emotions: Their Origins and Definitions

             Emotions are a vital part of our lives.  They increase human interaction and allow us to express our feelings to those around us.  But where do emotions come from? How do we interpret a situation which makes us happy or sad? If the definition of emotion varies, then how does this affect the treatment of patients with emotional disorders such as depression?
