| Prep. #10: the most boring control of them all - usually |
| Obviously, when you just observe the experiment and don't do anything to it at all, that's the most boring experiment one can think of. Nothing happens, in my special case of attempting to establish operant learning in ...[more] |

| Prep. #11: more supporting evidence |
| As the three people reading this blog know, I'm currently trying hard to somehow establish operant learning in isolated leech ganglia. This is preparation number eleven after some initial trying-out and getting used to t...[more] |

| The final week: the data so far |
| I've skipped blogging about the last two preparations in my seemingly endless quest towards establishing operant learning in isolated leech ganglia, because they both were very frustrating: in contrast to the previous pr...[more] |

| Noise in the brain? |
 I was recently alerted to a group of theoretical publications which deal with the issue of apparent 'noise' in neuronal populations. The Nature Reviews Neuroscience article "...[more] |

| Prep. #14: if only all experiments worked like this one |
| This was such a wonderful preparation. First, it took me only 2.5h for the dissection instead of the usual 3. Then, I was quickly able to adjust the stimulations such that the isolated leech nervous system would respond ...[more] |

| Final day at UCSD: data crunch |
| After catching my last few waves this morning, I'm now sitting at the computer evaluating the last weeks of research in the isolated leech nervous system. The main focus of the project was to do some pilot experiments ...[more] |

| Modulating decision-making in the isolated leech nerve-chord |
| For the last two weeks I've been trying to develop an operant learning paradigm for isolated leech nervous systems. To do these experiments I traveled to visit Bill Kristan's lab at UCSD. After he showed me how to dissec...[more] |

| Prep #5: making progress in leech operant conditioning, one preparation at a time |
Let's see how long I can manage to blog each day about each preparation  Slowly but steadily I'm making progress in my attempts to find out if one can get isolated leech nervous systems to learn. Here are the problems I'...[more] |

| Prep. #6: maybe increase the stimulation intensity? |
| In my attempts to establish operant learning in isolated leech ganglia I'm now at preparation number 6. In my last post, I promised to show some screenshots of the software I'm using, WinEDR. Here's a screenshot of the p...[more] |

| Mice on drugs |
| Have you ever wondered what happens in your brain when you take drugs? The University of Utah has put up a fantastic Flash animation of mice at a party and you can see all the different drugs and what they do to the tran...[more] |
