| 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] |

| Prep. #8: the first yoked control |
| The yoked control in operant conditioning 'yokes' one animal to another in terms of stimuli received. In my attempts to establish operant learning in isolated leech ganglia, if one preparation received a given number of ...[more] |

| Prep. #9: another yoked control following the trend |
| Somehow, I didn't really manage to adjust the posterior stimulation properly in this 9th preparation in my attempts to establish operant learning in isolated leech ganglia, it generated a swim/crawl ratio of 9-1. Don't k...[more] |

| 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] |
