We are now at the last week of the course. During this week the students have learned about how to use Drosophila as a model for studying complex behaviours such as courtship and aggression, as well as a model for human diseases. Now they are busy working in their final projects. They have paired in groups to perform the following short projects, which will help them to apply in one project everything that they have learned during the course:
 | |
| Nelson sorting male pupae for the for the aggression experiments |
Group 2 (Bolaji): Will test the role of chordotonal neurons in larval crawling and compare it to the role of pickpoket neurons.
Group 3 (Maureen, and Lucille): Will perform memory experiments in control and dunce mutants. They will perform two paradigms: larval olfactory associative memory assay, and proboscis extension habituation and sensitization assay.
 | |
| Steven prepearing to perform antennogram recordings in Drosophila |
Group 5(Goji, Abba, Ezekiel, Paulin): Will perform behavioural olfactory assays in adult and larvae of lab and wild Drosophila.
Group 6(Steve): Will try to perform antennograms and single sensillum recordings from Drosophila and Musca antennae.
Group 7 (Alfred, Sam, Ngattu): Will perform electroretinogram recordings in various species of insects, including Drosophila to compare the temporal resolution of their visual system.
Group 7 (Alfred, Sam, Ngattu): Will perform electroretinogram recordings in various species of insects, including Drosophila to compare the temporal resolution of their visual system.
They have to carry out the required literature research, built the experimental set-up, perform the experiments, analyze the data, and drawn conclusions. They will give a 15 minute PowerPoint presentation on Saturday in which they will introduce the problem and present their results and conclusions.
Here you can see some of the pictures from students engaged in doing their projects.

| The electroretinogram set up, now they have recorded from grasshopers, Musca, and Drosophila! The set up consists of an improvised pulse generator (with a computer and a custom made inexpensive electrophysiology amplifier) connected to an LED, and an electrophysiology set-up consisting of a custom made amplifier connected to an ADinstruments acquisition board. |

Here is a great herbal doctor who cured me of Hepatitis B. his name is Dr. Imoloa. I suffered Hepatitis B for 11 years, I was very weak with pains all over my body my stomach was swollen and I could hardly eat. And one day my brother came with a herbal medicine from doctor Imoloa and asked me to drink and I drank hence there was no hope, and behold after 2 week of taking the medicine, I started feeling relief, my swollen stomach started shrinking down and the pains was gone. I became normal after the completion of the medication, I went to the hospital and I was tested negative which means I’m cured.
