VTA (Ventral tegmental area) functionally connects to BLA glutamatergic principal neurons

Species: Mouse
Result: present
Method: optogenetic circuit mapping
Sign: excitatory
Evidence: Some BA excitatory neurons received glutamatergic currents from photostimulated VTA dopaminergic terminals. These currents were smaller and less common than in fast-spiking interneurons, depressed strongly with repetition, and did not trigger spikes.

Named in the paper: “VTADA➜BA axons” and “excitatory neurons (ENs) in BA”
Made by: an AI model reading the paper (claude-opus-5-5, extract@0.3.0), 2026-10-09
Checked by: a second AI model (claude-opus-5) agrees, 2026-10-09
“The paper reports glutamatergic currents in BA excitatory neurons, smaller and less frequent than in FS INs and insufficient to evoke spikes.”
Status: proposed
Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
