Method of experimental synaptic conductance estimation: Limitations of the basic approach and extension to voltage-dependent conductances
2018, NeurocomputingCitation Excerpt :In the present paper, we investigate the most vulnerable assumption of the method, that the synaptic conductances are voltage independent. The conventional multi-trial method of continuous conductance estimation originally used the voltage-clamp (VC) recording mode [9], and then it was modified to use the current-clamp (CC) recording mode [1,4]. The CC version uses stimulus-evoked voltage responses that are recorded at two or more levels of injected constant current.
Intracellular recording in behaving animals
2012, Current Opinion in NeurobiologyCitation Excerpt :However, while some aspects of neural activity appear to be preserved across anesthesia and awake states, many features appear to uniquely correspond to the awake brain (Figure 1). On the one hand, recent work has shown that the shape of orientation [9,10•] and other [11] tuning is similar in the awake and anesthetized brain, thus detailed intracellular studies of the synaptic mechanisms underlying such tuning in anesthetized animals [12–15] should apply directly to awake conditions. On the other hand, it was also shown that response magnitudes are strongly modulated by behavior in the awake animal [10•,16,17••], highlighting the dynamic nature of processing in the awake state.

2005, Progress in Biophysics and Molecular BiologyCitation Excerpt :This situation may change as new optical imaging techniques are developed, perhaps based on fluorescence imaging (Margrie et al., 2003), scattering of reflected light or optical coherence tomography (Boppart et al., 1996). To date electrophysiological recordings of AP backpropagation in vivo have been limited to single-electrode recordings obtained ‘blind’ (Borg-Graham et al., 1996; Buzsáki et al., 1996; Charpak et al., 2001; Debarbieux et al., 2003; Kamondi et al., 1998; Margrie et al., 2002; Svoboda et al., 1999; Zhu and Connors, 1999). Until dual recordings are feasible in vivo, reliable interpretation of in vivo data will require direct comparison with dual recordings from similar neurones in brain slices (Waters et al., 2003).
