🧪 The Sjöström Lab in Montreal is looking for a postdoc! We study cortical circuits, synaptic plasticity, and NMDAR signalling using custom 2-photon microscopy and optogenetics. We seek candidates with strong patch-clamp and/or 2-photon imaging expertise, and a relevant publication track record.

Interesting work by Tony Lien & @haiderlab.bsky.social. They reveal how some frontal cortex neurons mirrors V1 neurons. Responses lag visual cortex (VC) by ~25ms, with strikingly similar receptive fields—yet lacking a topographic map. Crucially, silencing VC abolishes these responses. Congrats
