Paired recordings in cat and mouse show thalamic reticular nucleus (TRN) neurons provide spatially tuned inhibition to dorsal lateral geniculate nucleus (dLGN) relay cells, with comparable receptive-field sizes.
- Why it matters: Crick’s attention hypothesis implies TRN could also deliver selective, localized inhibition that shapes sensory processing, but cross-species evidence for this sensory role was limited.
- What they did: The study compared prior cat recordings with new mouse visual recordings, estimating receptive-field size and structure in TRN and dLGN, and using paired recordings to assess burst firing and spike-rate modulation.
- The result: TRN activity is linked to burst firing in dLGN as well as changes in spike rate, implying fine-tuned contributions to early visual processing beyond attentional regulation.
