The behaviour of single receptors in the statocyst of the lobster Homarus americanus was studied by moving single receptor hairs or the statolith with a micro-needle while recording the electrical activity from single sensory neurons innervating these hairs. After removing the statolith, the sensory hairs formerly in contact with it assume an angle of about 40° from the cyst floor and in this resting position the associated sensory neuron discharges spontaneously. Movement of a statolith hair…

Functional polarization of statocyst receptors in the crayfishProcambarus clarkii Girard
TLDR
It was concluded that most of the statocyst receptors are functionally polarized toward the center of the crescent, and the role of those receptors without any plane of functional polarization, is different from that of the other receptors in producing equilibrium responses.
Recording from Sensory Cells in the Statocyst of Astacus
TLDR
It was shown that different tilts during circular rotation of the statocyst about its roll axis can be well discriminated by responses of many crescent-group receptors, and a similar discrimination of tilts about the pitch axis could be achieved only by response of transverse-group cells.
A VIBRATION-SENSITIVE DESCENDING STATOCYST INTERNEURONE IN THE CRAYEISH PROCAMBARUS CLARKII
TLDR
The overlapping of central projections, together with the properties of the response of B 1 suggests that the interneurone receives excitatory input from the phasic-type receptors and transmits information aboutphasic body movement, but not static positional information, to the posterior ganglia.
Statocyst-induced eye movement in the crab Scylla serrata. I. The sensory input from the statocyst.
TLDR
Electrical recordings from the three types of receptor hairs show that the thread hairs are most probably the receptors responsible for detection of rotation about the vertical axis and the free hook hairs are sensitive enough to detect rotationAbout the horizontal axes.

TLDR
It is concluded that the hair receptors of the inner row inform the crab about the direction and amplitude of the positional changes but that they can not code for the absolute position of the body in space.
Mechanosensory afferents innervating the swimmerets of the lobster
TLDR
Feathered hair sensilla fringe both rami of the lobster (Homarus americanus) swimmeret were observed, which may be activated by the turbulent flow of water produced by the swimmerets during their characteristic beating movements.

TLDR
Results suggest that separate pathways from the leg proprioceptors and the statocyst organs to the uropods exist and converge at a late stage in the pathway, within the terminal (6th) abdominal ganglion.

The purpose of this study is to investigate receptors in the invertebrate statocyst by recording action potentials from the primary afferent neurones by investigating the most intensive investigation of statocysts, both from a morphological and physiological standpoint.

TLDR
A preparation of a single Pacinian corpuscle in the cat’s mesentery has been used to study the initiation of nerve impulses in sensory endings and it is suggested that these results can all be accounted for in terms of the known properties of axons.
PROCESSES OF EXCITATION IN THE DENDRITES AND IN THE SOMA OF SINGLE ISOLATED SENSORY NERVE CELLS OF THE LOBSTER AND CRAYFISH
TLDR
The stretch receptor organs of Alexandrowicz in lobster and crayfish possess sensory neurons which have their cell bodies in the periphery and it is concluded that, once threshold excitation is reached, the generator potential within slow cell dendrites is well maintained for the duration of stretch.

TLDR
An error has arisen from the confusion of two separate and distinct organs situated, the one at the base of the larger or second pair of antennæ, and the other at the Base of the smaller or first pair, to each of which the function of an organ of hearing has been assigned by different anatomists.

The response spectrum of taste fibres in the cat: a single fibre analysis.
TLDR
It is proposed that the presence of the “water” fibre extends the sensitivity to salt solutions beyond the concentration limits served by the ”salt” fibres thus enabling discrimination of salt concentration over the entire physiologically significant saline range.
Neuron doctrine and electrophysiology.
TLDR
Although this is not inherent in the original anatomical concept, the neuron has classically come to be regarded as a functional unit, and it is here that newer information forces a reappraisal.
