Hybrid experimental and model approaches for the caracterization of Lymnaea stagnalis neural activity. Part. I: Experimental and theoretical characterisation of CPG activity in Lymnaea stagnalis

Máster en Investigación e Innovación en las TICs ; Central Pattern Generators (CPG) are neural circuits that produce and coordinate rhythmic motor activity. Their robust rhythms consist of sequences of neuron activations, which result in e ective motor patterns. These rhythms are at the same time exible and can adapt as a function of the behavioral context. This work characterises the intervals that build up the rhythm and the associated sequence of the feeding CPG of the mollusc Lymnaea Stagnalis. The study entails both the activity obtained in electrophysiolocal recordings of living neurons and in a realistic conductance-based model. The analysis reported here assesses the quanti cation of the variability of the intervals and the existence of relationships between some of these intervals and the period in the form of dynamical invariants.
