Of these, 21 out of 113 recordings showed an increasing firing rate as the input frequency increased from 10 Hz to 50 Hz, 28 recordings showed a decreasing firing rate with respect to the stimulus frequency, and the remaining 64 recordings showed no significant changes of firing rate as input frequency was varied.
Software-based analysis of video recordings showed a decreased 'total directionality' in PTZ treated flies compared to control, i.e., flies treated with normal food (NF).
64 However, when we performed a separate analysis for long-term and short-term recordings, we found a decrease for SDNN and rMSSD in both short-term and long-term recordings, although the decrease in long-term recording for rMSSD was statistically not significant (p=0.21).
The average data from 11 recordings (Figure 3B) revealed a decrease in slope as well as a left-shift with 2 µM Calindol.
In our preparation, we found a slight but not significant decrease in the maximal AP rate of rise to decrease in both paired and unpaired recordings indicating, if anything, a decrease in Na+ channel efficacy with LTP (Figure S4A and B).
In subsequent recordings, a slow total fluorescence decrease was observed that resulted from chromophore bleaching, even without any external application of amides.
Recordings of the synaptic response revealed a decrease in postsynaptic quantal size, consistent with the reduction in GluR levels.
During REM sleep we found a decrease of beta power in the hippocampal recordings.
A change in vital signs was defined as an increase in MPB or PR by 20% or more, or a decrease in SaO2 to 90% or less between the two recordings.
In electrophysiological recordings, loss of postsynaptic Dg did not affect postsynaptic response, but, surprisingly, led to a decrease in glutamate release from the presynaptic site.
