Neurons in the lateral geniculate nucleus (LGN) of the thalamus produce spikes that can be classified as burst spikes and tonic spikes. Although burst spikes are generally associated with states of sleep and drowsiness, bursts may also play an important role in sensory processing. This study explores the stimulus properties that evoke burst and tonic spikes and examines the reliability of LGN n...
background : young chickens are more susceptible to salmonella colonization than older ones that have developed resistance with age as native microflora become established. methods : in this study, two groups of fertile eggs were inoculated with 20 cfu of hila or parent strains of s . enteritidis . presence and number of salmonella cells inside the homogenized egg contents were determined on...
OBJECTIVE To investigate: 1) the impact of clinical varicocele on reactive oxygen species (ROS) levels in neat and washed semen in a proven fertile population; and 2) the correlation between ROS levels, testicular volume, and varicocele grade in the same population of fertile men. DESIGN Prospective controlled clinical study. SETTING Andrology laboratory at tertiary-care hospital. PATIENT...
Extrasomatic (ES-) spikes were recorded in motoneurons in cats anesthetized with pentobarbital sodium and immobilized with d-tubocurarine. ES-spikes, 40-79 mV in amplitude, were distinguished from intrasomatic spikes by their differences in responses to a train of 8 pulses at 500 Hz given to the L 7 or S 1 ventral root. In 23 motoneurons 3-6 different spikes could be recorded from the same site...
