The representational geometry of emotional states in basolateral amygdala

Pia-Kelsey O’Neill, Lorenzo Posani, József Mészáros…·C. Daniel Salzman

The paper investigates how the basolateral amygdala encodes emotional states through representational geometry, finding that valence and motor responses are encoded in orthogonal directions enabling specialized readouts.

Prelimbic-dependent activation of amygdala somatostatin interneurons signals non-aversive cues to promote discrimination.

Joseph M. Stujenske, Pia-Kelsey O’Neill, Itzick Nahmoud…·Ekaterina Likhtik

This study shows that prelimbic cortex-dependent activation of basolateral amygdala somatostatin interneurons promotes discrimination of non-threatening stimuli by blocking theta-oscillation phase resetting.
