| 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] |

| Arrived in La Jolla |
| For the next six weeks I'll be staying in sunny southern California to perform experiments in Bill Kristan's lab at UCSD. I'll be working on the neurobiological basis of decision making in leeches. Specifically, I'll be ...[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] |

| Spontaneous activity in the isolated leech nervous system |
| As reported earlier, I've now been working for a couple of days in Bill Kristan's lab at UCSD in La Jolla, California. The first few days I was practicing the dissection of the leech nervous system. I need to take the en...[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] |

| Prep. #7: controls are important |
| This is preparation number seven in my attempts to establish operant learning in isolated leech ganglia and it's a control preparation, which means I'm just stimulating it every three minutes at ganglion 18 for an hour a...[more] |
