Ventral Pallidum GABA Neuron Inhibition Augments Context-Appropriate Defensive Responses to Learned Threat Cues

This study inhibits VP GABA neurons and finds it increases context-appropriate defensive responses to learned threat cues without affecting memory formation.

Parkinson's disease-vulnerable and -resilient dopamine neurons display opposite responses to excitatory input

The paper identifies Anxa1 as a marker for PD-vulnerable dopamine neurons and shows they respond oppositely to excitatory inputs compared to resilient Vglut2+ neurons.

Ventral tegmental area interneurons revisited: GABA and glutamate projection neurons make local synapses

This study challenges the traditional view of VTA interneurons by showing that GABA and glutamate projection neurons in the VTA also form local synapses, suggesting they may fulfill roles previously attributed to interneurons.

Proportion and distribution of neurotransmitter-defined cell types in the ventral tegmental area and substantia nigra pars compacta

The paper quantifies and maps neurotransmitter-defined cell types in VTA and SNc using fluorescent in situ hybridization, revealing diverse distributions and proportions.
