Odor Response Properties of Rat Olfactory Receptor Neurons
TL;DR: The selectivity of olfactory receptor neurons was investigated in the rat at the cellular level under physiological conditions by unitary extracellular recordings and it is concluded that peripheral coding is based on activated arrays of ofactory receptor cells with overlapping tuning profiles.

Single olfactory sensory neurons simultaneously integrate the components of an odour mixture
TL;DR: The present study compares the electrical responses of single OSNs to two odour molecules, delivered singly and mixed together, in rats in vivo, and concludes that the observations with binary mixtures anticipate the complexity of processes which may rise at the level of a single OSN in physiological conditions.

TL;DR: The data on serotonin action on juxtaglomerular cells and mitral cells reveal a part of functional mechanisms whereby serotonin can act on olfactory bulb network, which is expected to enrich the understanding of its determining role inOlfactory learning.

Amplifying role of convergence in olfactory system a comparative study of receptor cell and second-order neuron sensitivities.
TL;DR: The demonstration that the convergence of receptor cells onto second-order neurons is functionally implicated in an amplification process of the primary signal in olfaction is demonstrated.

Spontaneous activity of first- and second-order neurons in the frog olfactory system.
TL;DR: The spontaneous activity of first- order neurons (neuroreceptors of the mucosa) and second-order neurons (mitral cells of the bulb) was recorded extracellularly in the frog olfactory system to assess the influence of peripheral inputs upon mitral cells, and it was found that most neurons generated interspike intervals that were stationary in mean and variance, and were not serially correlated at first and second order.
