Research in the context of scent has unveiled a myriad of profound associations due to the evolutionary significance of the chemosensory system across species and the close proximity of the olfactory bulb (both anatomically and functionally) to the limbic system (associated with learning, memory, emotion) in humans.
Additionally, given how short the sonic logos are, we suggested approaching the study via Event-Related Potentials (ERP) Analysis. ERP measurement is very well suited to studying the brain’s response to short sound stimuli. Most natural sounds in the world vary in spectral content over time and the brain’s registration of these changes can be monitored through ERP measurements on a millisecond by millisecond basis.
Auditory ERPs can give valuable information about certain stages of auditory processing, either with or without attentional engagement of the listener to the event. In every ERP experiment, repetition is the key. The necessary total amount of same-event repetitions varies with the experimental paradigm and the ERP component of interest, but the general rule is that more trials will result in cleaner averaged waveforms
