Auditory-nerve and energy-detection models of temporal summation in hearing: a theoretical and experimental investigation
… of a psychoacoustic experiment concerning temporal summation of human hearing are investigated. The experiment has the well-established result that, ceteris paribus, a brief tone burst is more readily letected than a brief gap in a tone. Two models, one based on the neuroelectrical activity …

Testing the limits of human vision with quantum states of light
… including the length and completeness of temporal summation, which we have investigated in detail with a new experimental paradigm. We found that temporal summation continues for at least 650 ms when photons are delivered at a rate of about 30 in 100 ms, and that the completeness of …

The role of hyperpolarization-activated non-selective cation current in amygdala excitability and serotonin mediated effects.
… brain, participating in network oscillations, temporal summation of synaptic inputs, and seizure development. Since hyperexcitability of the amygdala is related to anxiety and stress disorders, we investigated the role of Ih in amgydala excitability. In lateral amygdala (LA) pyramidal neurons, …

Model Based Decomposition of MUAPS Into Their Constituent SFEAPS
… potential (MUAP) represents the spatial and temporal summation of single fibre extracellular action potentials (SFEAPS) generated from the same motor unit. MUAP morphology is affected by structural reorganisation of the motor unit that takes place due to disorders affecting peripheral nerve …

The Role of Synaptically Evoked Plateau Potentials in Retinogeniculate Development
… the high degree of retinal convergence, the temporal summation of excitatory post-synaptic potentials, and the lack of inhibitory connections) seem to favor their activation at early postnatal ages. We then tested whether such activity is necessary for the refinement of retinal projections, …

Coincidence detection in the cochlear nucleus : implications for the coding of pitch
The spatio-temporal pattern in the auditory nerve (AN), i.e. the temporal pattern of AN fiber activity across the tonotopic axis, provides cues to important features in sounds such as pitch, loudness, and spatial location. These spatio-temporal cues may be extracted by central neurons in the …

Utilisation des mécanismes endogènes de modulation de la douleur en contexte clinique : élaboration de valeurs normatives, mesure de la fidélité test-retest et développement et validation d’un modèle de prédiction
Introduction : Les mécanismes de modulation de la douleur sont des processus physiologiques qui régulent la perception de la douleur. La sommation temporelle (ST - mécanismes excitateurs) et les CPM (mécanismes inhibiteurs) ont particulièrement été étudiés à cet égard. D'une part, ils apparaissent …

Temporal Dynamics of Heat Pain Sensations
… this thesis sought to 1) characterise the temporal profiles of the most prominent noxious heat-evoked sensations, 2) characterise sex differences in these sensations, 3) evaluate the magnitude of sharp pain quality evoked in hairy and glabrous skin, and 4) determine the role of absolute …
