Real-time models contend that a conditioned stimulus (CS) gives rise to a cascade of hypothetical stimuli that govern conditioned responses (CRs) on a moment-by-moment basis. Experiments with the rabbit nictitating membrane response successfully extended these models to external stimuli. CSs were trained in sequence with an unconditioned stimulus(More)
Voltage clamp fluorimetry (VCF) utilizes fluorescent probes that covalently bind to cysteine residues introduced into proteins and emit light as a function of their environment. Measurement of this emitted light during membrane depolarization reveals changes in the emission level as the environment of the labelled residue changes. This allows for the(More)
In studies of learning using rabbits, there has been standardization of behavioural procedures across laboratories. Less attention has been paid to variation that may arise from genetic differences and/or differences in rearing conditions. The present experiment revealed that acquisition of a conditioned reflex can be affected dramatically by such(More)
Using results from synoptic measurements we developed a statistical frequency distribution more suitable for aquatic plankton than existing ones. We analyzed the synoptic data with this distribution and used the results to quantify phytoplankton spatial relations and to investigate controlling physical and ecological factors, We analyzed 43 sets of data(More)
