Evaluate frontal area targeting strategy for neuropixel with 4 shanks probes

[jeromelecoq]

We have newer neuropixel probes with 4 shanks available at The Allen Institute.

Those probes are spread laterally across 1 mm and allow to record a distributed set of local areas.
When recording from areas such as prefrontal cortex, this could be beneficial as those have not clear well defined boundaries.

The goal of this effort is to evaluate the feasibility of using 4-shanks for frontal areas recording in the predictive processing work.
