With repetitive stimulation of two sensory pathways which are intact within the isolated nervous system of Hermissenda, features of a cellular conditioning paradigm were identified. Type A photoreceptors, unlike type B photoreceptors, produce fewer impulses in response to light following temporally specific pairing of light stimuli with rotation stimuli. Type A photoreceptor impulse wave-forms ...

We have developed a computer interface that simultaneously renders integrated auditory and haptic stimuli with very low latency. The interface includes a three degree of freedom (DOF) Pantograph haptic device that reads position input and renders force output. We synthesize audio by convolving the force profile generated by user interaction with the impulse response of the virtual surface. Thus...

Brainstem auditory evoked potentials (BAEPs) were studied in 10 chronic male tobacco smokes (average age 26.55 years) with history of smoking 3 to 14 years to detect early subclinical impairments in auditory pathway. The values of BAEPs were compared with those of 28 age matched normal male non-smokers (control). The results revealed significant prolongation of latencies of wave I and III indic...

We describe a patient with noninsulin-dependent diabetes mellitus presenting with an amnestic disorder, personality change, and autonomic seizure. Magnetic resonance images of the brain showed T2-high signal lesion in the hippocampi bilaterally and nonspecific white matter disease, while single photon emission computed tomography revealed a diffuse reduction of cerebral blood flow. Sensory and ...

This review considers the ion channels that underlie transduction of nociceptive energies in the periphery, that are involved in impulse initiation and propagation in peripheral sensory neurones, and that participate in pre- and post-synaptic actions in the spinal cord dorsal horn, in light of their susceptibility to local anaesthetics. Although there are results from experiments on isolated ce...

Virtual reality (VR) storytelling, particularly in its nonfictional modes, promises a sensory immersion among others whose lives and ways of being privileged viewer might not otherwise experience. In this essay, by focusing on the Emmy-nominated 2018 VR film Traveling While Black, we explore how immersive power storytelling can enact ethnographic encounters premised less impulse to extract mean...

To probe how the brain integrates visual motion signals to guide behavior, we analyzed the smooth pursuit eye movements evoked by target motion with a stochastic component. When each dot of a texture executed an independent random walk such that speed or direction varied across the spatial extent of the target, pursuit variance increased as a function of the variance of visual pattern motion. N...

Extracts of whole nerve (chelipeds of Cancer magister) cause inhibition of impulse generation of the crayfish stretch receptor preparation, similar to that produced by gamma-aminobutyric acid (GABA). This is not found with extracts containing only sensory or sensory and motor fibers. Extracts of inhibitory fibers inhibit the stretch receptor discharge-indicating an inhibitory action equivalent ...
