  Research Area

Neurobiology of the gastropod nervous system.


  Research Description

 Anatomical, behavioral, biochemical, and physiological analysis of the dopaminergic and serotonergic systems during the different phases of food ingestion in gastropods. 
The role of octopamine neurons in the reorganization of the feeding pattern generator network activity in the pond snail Lymnaea stagnalis.

Monoamine specific neurotoxins as tools to study the gastropod feeding behavior.
Principles in the organization of the gastropod central and peripheral nervous system (mapping sensory and motor centers in the gastropod brain applying neuroanatomical and electrophysiological approaches).
