Intracellularly recording from pyramidal cells in a mouse

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

I am recording intracellularly from the neocortex of a mouse. If I place my electrode on one set of pyramidal neurons (Layer 2) and add fenfluramine (a serotonin uptake blocker), whithin 5 minutes the neurons produce GREATER amount of action potentials. But when I place fenfluramine while recording from another set of pyramidal cells (Layer 5 for example), the neurons showed a DECREASE in AP's (action potentials) after 5 minutes of treatment. How is this possible for one drug to affect similar cells in completely different methods?

Please offer any feedback - if you feel that I haven't explained the question well enough, or if you aren't certain what I am looking for, please let me know. I am looking for help getting started on this and am hoping that you can provide some guidance.

Hi There,

Sorry for the delay in responding, but I have been experiencing some Microsoft Runtime Errors with internet explorer.

I found your posting to be very interesting. My approach to neuronal physiology is from how changes in neuronal physiology ultimately affect (or effect) the animal's behavior. Namely, my approach to this posting was in considering how and why one drug or chemical would affect similar cells differently, and why this sort of experimental manipulation may ...

Solution Summary

Neuron Bathed in Muscimol & Baclofen

Please see the attached figure. This is from the cerebellum of a rat.

Plate 1 shows the normal activity of a neuron. Plate 2 shows the activity of a neuron after being bathed in muscimol (a GABAa agonist). Plate 3 shows the activity of a neuron after being bathed in balcofen (a GABAb agonist). Plate 4 shows the wash out of drugs. Explain this figure (i.e. what is happening at the synapse? Why is one type of GABA agonist more effective than the other? Explain how each receptor functions to affect synaptic activity.
