With the increase in number of sensory substitution devices, engineering community is confronted with a new challenge: ensuring user training safe virtual environments before using these devices real-life situations. We developed game that uses an original sonification model, which, although not specific to certain device, can be effective means for orientation space based on audio stimuli. Thu...

THE CRAYFISH TONIC STRETCH RECEPTOR NEURON MANIFESTS THREE PHENOMENA: (a) Impulse frequency in response to a depolarizing current decays exponentially to half the initial rate with a time constant of about 4 sec. (b) One or more extra impulses superimposed on steady activity result in a lengthening of the interspike interval immediately following the last extra impulse which is proportional to ...

To quantify the contribution of sensory information to multisegmental frontal plane balance control in humans, we developed a feedback control model to account for experimental data. Subjects stood with feet close together on a surface that rotated according to a pseudorandom waveform at three different amplitudes. Experimental frequency-response functions and impulse-response functions were me...

This study was undertaken to compare the excitability changes of sensory and motor axons during hyperventilation and ischaemia, and to determine why ectopic impulse activity develops more readily during hyperventilation, and in sensory fibres. During hyperventilation for 20 min, all six subjects reported paraesthesiae in the hand and face, and four out of the six developed muscle twitching and ...

Somatic sensation requires the conversion of physical stimuli into the depolarization of distal nerve endings. A single cRNA derived from sensory neurons renders Xenopus laevis oocytes mechanosensitive and is found to encode a P2Y1 purinergic receptor. P2Y1 mRNA is concentrated in large-fiber dorsal root ganglion neurons. In contrast, P2X3 mRNA is localized to small-fiber sensory neurons and pr...

The present investigation continues a previous study in which the soma-dendrite system of sensory neurons was excited by stretch deformation of the peripheral dendrite portions. Recording was done with intracellular leads which were inserted into the cell soma while the neuron was activated orthodromically or antidromically. The analysis was also extended to axon conduction. Crayfish, Procambar...

conclusions it can be indicated that reinforcing components of emotional intelligence, especially emotional-awareness and impulse control, are effective methods to develop against substance use in among drug-dependent individuals. background drug addiction is one of the most significant problems related to general health in the world, creating various mental problems in addicts and leading to s...

This paper reviews the affective neuroscience dealing with the effects of traumatic events. We give an overview of the normal fear reactions, the pathological fear reaction, and the character of emotional episodic memories. We find that both emotions and emotional memories are a tripartite unit of sensory information, autonomic reaction, and motor impulse (the PRM complex). We propose that emot...
