Neither manipulation of 5 - HT3 entirely eliminates the responses, suggesting that other neurotransmitters such as ATP participate in neurotransmission in this system. (jneurosci.org)
In fact, our understanding of neurotransmission in general is filled with holes, limiting the development of treatments for memory loss. (sciencedaily.com)
Given the role of serotonergic neurotransmission in cognitive control and impulsivity (Gorwood et al. 2000; Mann et al. 2001; Purselle and Nemeroff 2003; Retz et al. 2004; Strobel et al. 2007; Walderhaug et al. 2007; see, however, Clark et al. 2005 for negative evidence), the current findings of greater error - evoked thalamic activity in women seem to indicate a potentially useful intermediate neural phenotype to further elucidate gender differences in depression.
