Q

Describe the inputs/outputs to the medial CeA as discussed in Bienkowski & Rinamen (2013),

A

Medial CeA

  • primarily receives projections from cortical & sensory systems
  • projects directly to hypothalamic and brainstem motor systems
  • has indirects effect on responses via projections to BNST
  • receives relatively small amount of direct feedback from relevant motor/viscerosensory nuclei
  • receives most of its feedback about execution via a BNST-mediated pathway
  • relays feedback to cortex and sensory thalamic systems
2
Q

Where does the ventrolateral BNST project to, that the medial CeA does not (directly) project to?

A

Paraventricular nucleus. So the CeA does not induce long-term increases in peripheral CRH directly, but the BNST does.

3
Q

Bienkowski and Rinamin (2013) findings suggest that the ventrolateral BNST…

A

Receives most feedback regarding execution of motor outflow and interoceptive feedback (viscerosensory nuclei)
Relays this into back to the medial CeA
*Projects to the Paraventricular nucleus (CRH)

4
Q

Method (Bienkowski & Rinamin, 2013):

A

Into phonetic delivery of retrograde neural tracers into medial CeA and ventrolateral BNST to examine their axonal inputs.
