Intersex

  Imagine living a life as lie. Always feeling as if there was something wrong with you, feelings of not belonging. Then you find  out that as a child your parents were forced to make the decision of raising you as either a boy or a girl. Cases like these are not too rare and occurs only in 1 in 2000 people in the United States. It's called intersex, when sexual development is intermediate enough that it is uncertain whether the sex of the person is male or female. In the case of Debbie, formally Andrew, she felt uncomfortable with who she thought she was. Even though Andrew had a family and kids, it did not feel right.

       Gender identity is more than just physiological and rearing factors, there has to be something else that makes us feel comfortable with the role we've been placed in.

Animal Attraction

     The rules of attraction, a topic found in different branches of psychology. In physiological psychology attraction is all about survival of the fittest ;D.

    Pheromones are the chemicals that attract men and women to each other. Excreted through the skin, sweat glands, saliva and urine; these are the biological reasons for how and why we choose a potential mate. Disgusting right, its not like we go around smelling other people to see if they are our soul mates. However, these pheromones are what elicit sexual desires, hormone levels and sexual readiness.
       Obviously nobody consciously smells them when meeting someone. Pheromones work subconsciously to choose a genetically compatible mate. People who are genetically incompatible are actually turned off by each others smell. For example, you tend to avoid people who smell like your siblings; the reason is not because you don't like how your siblings smell but because by avoiding similarities in gene compatibility you avoid probability of incest and genetic mutations.
       Ever wonder why certain few lucky men always seem to be surrounded by women even if these men are not even handsome? Well the explanation for this lies in pheromones. About 10% of  men secrete significant amounts of a specific pheromone called androsterone, this gives him what we call "sex appeal". Hard to believe right, you want him because he smells "right", in an evolutionary sense, not because he looks good.
       Pheromones are also used in the perfume industry as the "seductive" ingredient

Alzheimer's

Everyone forgets things. We forget where we put our keys, if we fed the dog, did I lock my car, you know little things like that. But what if you were to forget where you were or how you got there; if one day your children went to see you and you didn’t recognize them? What if it got to the point that every time you would wake up it would be a whole new world? I suppose from the perspective of the patient they probably wouldn’t notice, but for a loved one of that person it can be pretty frustrating and sad. 
Alzheimer’s has no cure, it worsens as it progresses and eventually leads to death. It tends to happen with age, in people over 65 yrs of age. As it develops it’s symptoms are usually mistaken by stress or “age related concerns”. Some of the symptoms include:

·         Confusion

·         Irritability and aggression

·         Mood swings

·         Trouble with language

·         And long-term memory loss

    It is not easy predicting the outcome for this disease because it affects everyone differently. The progress isn’t well understood which makes it difficult for a cure to be found. People diagnosed usually live an average of seven years after  their diagnosis.

Agenisis of the corpus collossum

The corpus collossum is a bundle of nerve fibers that connect both sides of the brain. Obviously this is important if you want to use more than just one side of your brain.  Now imagine this very important connection is severed, what then? Well fortunately although the biggest and most used it is not the only connection of its kind. These smaller commissures allow the brain to rewire itself so that information can continue to flow as best as possible and one can continue to live a seemingly normal life with a few drawbacks.

                However, what if this connection never developed, is it better or worse in the sense of the brain being able to adapt? When the corpus collossum is absent it is known as agenesis. This condition is rare and is usually diagnosed by the age of two. Symptoms of ACC include seizures, feeding problems, problems holding the head erect, sitting, standing, and walking. Although ACC has many impairments it is non-fatal. Since an infant is born without the corpus collossum and the brain is still under relative development throughout their life, their brain can adapt around this disorder. For example, the other smaller commissures will grow larger than normal in order to compensate for the lack of the main connection. In fact studies have shown that people born with ACC lead normal lives and have an average intelligence if any there are some subtle differences in cortical function. Also revealed in recent studies is the correlation between corpus collassum malformation and autism spectrum disorders.
