...Lakhan S. Khara; Md Ruhul Amin; Declan W. Ali ABSTRACT The endocannabinoid system (eCS) plays a critical role in a variety of homeostatic and developmental processes. Although the eCS is known to be involved in motor and sensory function, the role of endocannabinoid (eCB) signaling in sensorimotor...

... SPL (particle velocity 605 μm s −1 ) at 150 Hz. When presented with a repeated 200 Hz sound tone, caterpillars habituate by no longer responding. A series of ablation experiments confirmed that the primary sensory receptors are a pair of long hairs, called trichoid sensilla, located on the upper...

.... This requires that they either move ballistically towards a pre-determined prey location or that they account for their self-movement and continually track prey. We found that leeches do not localize prey ballistically. Instead, they require continual sensory information to track their prey. Indeed...

The results from all of the species examined indicated asymmetric directional sensitivity, e.g. the pit would preferentially respond to stimuli located below and behind the snake. The present study was intended as a test of these findings...

... and probably most mammals causes immediate pain and often long-lasting hypersensitivity. Pain is defined as an ‘unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage’ ( Merskey and Bogduk, 1994 ). In mammalian pain studies, long-term...

...Ian C. Hall; George V. Rebec; Laura M. Hurley SUMMARY Neuromodulation by serotonin (5-HT) could link behavioral state and environmental events with sensory processing. Within the auditory system, the presence of 5-HT alters the activity of neurons in the inferior colliculus (IC), but the conditions...

...Andrea L.

It is likely that a variety of signals are involved in triggering this injury...

The cell bodies of the sensory neurons, in contrast, are located close to their sensory endings within the limb...
