Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Evidence from human fetal tissue studies confirms that neural spiking and spontaneous electrical activity begin early in development, regularly observed in pioneer neurons during midgestation.

The analysis

The retrieved literature includes direct empirical investigations (such as papers [0] and [4]) showing that human fetal cortical and subplate neurons exhibit spontaneous electrical activity and action potential firing during early gestational stages. There are no papers refuting this claim.

Electrical recordings from unfixed human postmortem fetal tissue demonstrate that spontaneous electrical activity, consisting of action potential firing and plateau depolarizations, occurs in subplate neurons as early as midgestation.
