:As thought experiments go this is a bit over the place. kg is a unit of mass not force. A force of 1kgf will produce an acceleration of 1000 m/s/s on the ball, so you are talking about a very dynamic event. The force will vary with time, and collisions or impacts are notoriously hard to analyse in the real world. However, in a perfectly elastic solution, if the peak force was 1 kgf, then there is no intrinsic difference between squishing the ball slowly, and then releasing it instantaneously, compared with bouncing the ball with the same peak force. In the real world of course there are many reasons why the subsequent rebound speed would differ, but you knew that. Another point of view, which may confuse more than it helps, suppose we took a snapshot at the point of maximum force on the wall, after the pressing force is released. It has a location, a velocity of zero, and an acceleration of -1000 m/s/s in both cases, there is no measurement that could be made that would be able to determine what the previous path of the ball had been.

:::::::Exactly: the current 'exciters' are the arrays of microelectrodes able to contact up to a thousand neurons at the same time. To measure or excite the 100 billion neurons of a brain you will have to use 100 million of these arrays and of course in three dimensions. Moreover it is likely that the state of excitation of the neurons at a certain moment has very little to do with the function of the brain, which is determined rather by the individual threshold of excitability stored in each synapse. As there are well within 10 thousand synapses on a single neuron you can see that there will not be so many authorities ready to spend all this money. But in any case you can look in [[Scientific_Research#Financing_of_Research]], the chapter on the financing of scientific research. The tendency being towards private funding, it would be advisable for you to emphasize to potential investors all the money that will be made with your invention the day it will be put on the market.

:To be honest, it's not clear what you are proposing and what you are trying to achieve. Reconstructing the connections of a (human?) brain in a computer simulation in order to obtain (or inflict) consciousness, similar to the notion of [[brain in a tank]]? What does this have to do with children? Should they understand the trial? Or do the brains to be dismantled have to be children's brains? Do you know that "[[nerve cell]]" and "[[neuron]]" mean the same thing? Removing the outer membrane is an effective way to destroy it. Connections are made through [[synapses]]s; they are not like electrical connections; knowing which neurons connect to which neurons does not give enough information to simulate the activity of the network formed by the neurons. &nbsp;--[[User talk:Lambiam|Lambiam]] 23:49, 4 November 2020 (UTC)

:::To this same question I told you a few weeks ago on the French oracle that in order to emulate the functioning of a specific brain it is necessary not only to know which of the 100 billion neurons is connected to which other, but also to know the specific excitability threshold of each of the 10,000 or so synapses belonging to each neuron. And it is quite possible that the excitability state of the synapses is lost at death.

Even if you can measure every neuron in a frozen brain to see how they are connected, it will not help you reconstruct, restore or even emulate the consciousness of the deceased, no matter what technology you use. And as long as no authority is interested in realizing your idea.
