The biggest wish of scientists is to get internal images of an organism without damaging its body. However, instead of getting the immediate spatial information of internal organs in an organism, we usually have a series of two-dimensional (2D) biological images in a plane due to the physical restrictions of laboratory equipments. In order to get the spatial information of internal organs in an organism, we could reconstruct the 3D image from a series of 2D images with the aid of the computer software. The reconstructed 3D model could be rotated in any directions. This helps us observe an organism’s structure in any angles and directions on a computer screen.
The signal processing and transmitting fascinate scientists the most. However, human has longer life span and has about 100 billion neurons, and it’s illegal to manipulate the human genes. Lots of the researches in neuroscience are carried out only in model animals, such as mice, zebrafish or Drosophila. There are only about 135 thousand neurons in the Drosophila brain. And the Drosophila could demonstrate complex behaviors, such as memory and learning. So, the Drosophila is favored in the study of neuroscience. Besides, Drosophila genome has been sequenced and it has a short life span (It’s about 60days). All those are helpful in the studying.
