I have always been curious about when the human brain comes "online" and starts becoming coherent of the things around. For instance, when does the brain start receiving sensory input from the nerves, and receiving infomation from eyes, skin, etc. This is a very interesting thing that should be studied, but is exteremley challenging, since most people don't remember when they actually did start percieving the enviornment around them!
I have suprisingly vivid memories of things in my childhood, and the amazing thing is when I encounter something totally benign to that refreshes that memory. For example, my parents had me up at the rescue squad they were in when I was just an infant. One day, I was in an old county office building that had an old phone system similar to what the rescue squad had during that time. When their hotline buzzer went off, I was able to vividly flashback to the day President Nixon resigned on August 8th...which was barely 2 weeks after I was born on july 27th!
Although I don't remember my birth, I do remember staying in the hospital right at birth. The hospital was brightly lit, and had those "dental tooth" strip lamps overhead that were rather common in the seventies. I also remember laying in the curved clear glass beds. My Mom thought I was crazy till she went to see a friend that had a child when I was a teenager. When she visited the nursery, she was quite suprised to see some of the rather insignificant things I had described in vivid detail in the nursery....things she had not payed attention to on previous visits till I had said something. What makes it all the most suprising is the fact that I had never been in that birthing nursery since I was born until I was at least 24 years old or so.
One of the memories I do have is that of being circumcised too. They say that we don't remember that young, but I do. I remember the intense pain of having it done. I remember a plastic object attached to my bits for an extended period that produced extreme pressure and pain. Later, as an adult, when I saw some information about circumcision, I saw a picture of the plastibell device used for circumcision. Instantly, I was literally feeling the intense pain that had accompanied my circumcision as an infant. Oviously, this was what was used. Out of this experience, I'll never have this brutal, needless thing done to my kids!
