For #neuropeptide afficionados:
Interesting new paper from James Checco's lab on two #Aplysia #allatotropin / #orexin receptors, one activated by a D-peptide the other one by an L-peptide.
Conversion of an L-stereoisomer to a D-stereoisomer is a big mystery in peptide biology - but it matters for rec specificity and lifetime.

Cephalopods such as #Octopus exhibit higher degree of complexity in their cognitive ability than gastropods such as #Aplysia.
Improved transcriptome assemblies in #Aplysia indicate that, in mollusks, increased complexity of the synaptic #proteome doesn't mirror enhanced cognitive sophistication.

#introduction (2).
I am a neurophysiologist interested in decision-making systems constituted of small number of neurons, whose functional/synaptic properties and individual involvement in genesis of a behavior are identified.
Hopefully, I will be able to share some science soon.
