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; Debanne & Inglebert, Curr Opin Neurobiol 2023), 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; Bouddkazi & Debanne, Cells 2023) 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 neuronal excitability in cortical and subcortical neurons and their role in learning, development and sensory adaptation, 2) the cellular and molecular mechanisms of amblyopia, 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).
