The group of Marco Capogna in collaboration with previous Unit members (Francesco Ferraguti, Yannis Dalezios) publishes on distinct functions of intercalated cell masses of the amygdala in the Journal of Neuroscience, 31 (13): 5131-5144, 2011.
Intercalated cell masses have been implicated in acquisition and consolidation of extinction learning. Busti et al. reports that these neurons are more heterogeneous than previously appreciated. By using cell labelling and electrophysiological techniques, three distinct cell clusters were identified exhibiting distinct axonal projection patterns and differential activation after fear learning and fear extinction.
The paper has been selected and evaluated this week by Gary Aston-Jones, a Member of the Faculty of 1000 (F1000), which places it at the top 2% of published articles in biology and medicine (F1000 evaluation for this paper).
