Relationship between spiking activity and simultaneously recorded fluorescence signals in transgenic mice expressing GCaMP6
Huang, L., Knoblich, U., Ledochowitsch, P., Lecoq, J., Clay Reid, R., de Vries, S.E.J., Buice, M.A., Murphy, G.J., Waters, J., Koch, C., et al.

Two-photon calcium imaging is seeing a great uptake in popularity as a way to measure large-scale neural activity in the brain. However, much like fMRI, the relationship between the measured signal and the signal of interest (neural spiking) is not known. Here, Huang et al. present heroic work where they recorded spiking and calcium florescence from 91 neurons in vivo from layer 2/3 primary visual cortex in transgenic mice. Along with a number of separate analyses, they demonstrate that calcium imaging has higher spike-detection rates at high-resolution imaging, but detection decays substantially when imaging at spatial resolutions that are more commonly employed (10-15% correct detection). Most exciting is that this data is freely available at https://portal.brain-map.org/explore/circuits/oephys. —SA

Variability in the analysis of a single neuroimaging dataset by many teams
Botvinik-Nezer, R., Holzmeister, F., Camerer, C.F., Dreber, A., Huber, J., Johannesson, M., Kirchler, M., Iwanir, R., Mumford, J.A., Adcock, A., et al.
bioRxiv, 843193 (2019)
https://www.biorxiv.org/content/10.1101/843193v1

When analyzing fMRI data, we are faced with many choices: which software package to choose, how to define regions of interest, whether or not we should apply spatial smoothing etc. In this paper, 70 independent teams analyzed the same dataset testing predefined hypotheses, with their own analysis pipelines. Botvinik-Nezer and colleagues show that variation in scientific conclusions across teams is sizeable, and point out analytic choices related to biggest variability in results. —EB

Influence of kinesthetic motor imagery and effector specificity on the long-latency stretch response
Forgaard, C.J., Franks, I.M., Maslovat, D., and Chua, R.
J. Neurophysiol. 122, 2187–2200 (2019)
https://dx.doi.org/10.1152/jn.00159.2019

In this final study of my PhD thesis, I used motor imagery and contralateral responses to test the relationship between the overt execution of a voluntary response in stretched muscle and instruction-dependent long-latency reflex (LLR) facilitation. A high proportion of overt response “leaks” were found where the mentally simulated or mirrored response appeared in stretched muscle. The first half of the LLR was categorically sensitive to the appearance of leaks, whereas the latter half displayed characteristics closely resembling activity in the ensuing voluntary period. Critically, the LLR on non-leaked trials was indistinguishable from a passive control condition. These findings suggest that instruction-dependent facilitation of the LLR does require the overt execution of a motor response during the voluntary epoch of stretched muscle. —CF
