larval zebrafish Alix Lacoste Methods in Computational Neuroscience Final Project Presentation August 2011 Arousal in larval zebrafish is correlated with rest Fish are more active during the day than at night. Visual stimuli with emotional significance that are not perceived consciously nevertheless induce behavioural and neurophysiological responses that are indicative of a change in emotional state The notion that emotional events are sometimes not acce Physical Responses.

Target stimuli are things that we know the suspect knows, whether he/she committed the crime or not. We make sure he/she knows these things before the test. Since he/she recognizes the targets as significant in this context, his brain emits an “Aha!” response. This is called a P300-MERMER (memory and encoding related multifaceted electroencephalographic response). It has a positive followed by a negative voltage at the midline parietal area (middle of the top of the head near the back). It looks like a peak followed by a valley in the red line.. responses to stimuli in . larval zebrafish. Alix Lacoste. Methods in Computational Neuroscience. Final . Project . Presentation, .
