Was previously discovered that in the leech Hirudo medicinalis, acetyl-l-carnitine (ALC) affects forms of non-associative learning, such as sensitization and dishabituation, due to nociceptive stimulation of the dorsal skin in the swim induction behavioural paradigm, likely through modulating the activity of the mechanosensory tactile (T) neurons, which initiate swimming. Since was found that ALC impaired sensitization and dishabituation, both of which are mediated by the neurotransmitter serotonin, the present study analyzed how ALC may interfere with the sensitizing response. Was already found that ALC reduced the activity of nociceptive (N) neurons, which modulate T cell activity through serotonergic mediation.
