Scientific summary

My main scientific achievements are: 1) discovery of the spike timing-dependent plasticity (STDP) rules in the hippocampus in vitro (Debanne et al., PNAS 1994; Debanne et al., PNAS 1996; Debanne et al., J Neurophysiol., 1997; Debanne et al., J Physiol. 1998; Debanne et al., J Neurosci. 1999; Inglebert et al., PNAS 2020), 2) mechanisms of short-term synaptic plasticity at unitary synapses (Debanne et al., J Physiol. 1996), 3) characterization of propagation failures along the axon (Debanne et al., Nature 1997; Kopysova & Debanne, J Neurosci. 1998), 4) Hebbian plasticity of intrinsic excitability (Daoudal et al., PNAS 2002; Campanac & Debanne, J Physiol., 2008; Campanac et al., J Neurosci. 2008; Campanac et al., Neuron 2013; Incontro et al., J Neurosci 2021; Sammari et al., PNAS 2022), 5) mechanisms and plasticity of neuronal timing (Sourdet et al., J Neurosci. 2003; Boudkkazi et al., Neuron 2007; Cudmore et al., J Neurosci. 2010; Boudkkazi et al., J Physiol. 2011, Gastrein et al., J Physiol 2011; Campanac et al., Neuron 2013) and 6) the role of axonal ion channels in information processing (Rama et al., Nat Commun 2015, Zbili et al., Sci Adv 2020; Zbili et al., PNAS 2021).

My current reseach is focussed on 1) the mechanisms of long-lasting, plasticity of intrinsic excitability in cortical and subcortical neurons, 2) the determinents of action potential threshold, 3) the role of axonal ion channels in information processing and 4) spike-timing-dependent plasticity (STDP) rules in physiological conditions.

To address these questions, we employ 1) multiple whole-cell patch-clamp recordings in brain slices (from two connected neurons or from the axon / cell body), 2) laser scanning microscopy imaging (Ca2+, Na+, voltage), 3) computer modeling, 4) hybrid neuron-computer techniques (dynamic-clamp, hybrid networks) and 5) molecular tools (single neuron electroporation in slice cultures).
